new build...338??

Thanks Mark for putting this to words better than I did.
I am not saying that the recoil is less only that it is handled in a different way by the shooter.

I was amazed when my son shot 40 rounds from 1 of my 338s when he was 8 years old. I figured 1 shot would be all she wrote, then it occurred to me while watching him shoot it he was being pushed back under recoil ALOT more than I was when shooting the same rifle.
The recoil the rifle produced was the same, he was just "riding" the rifle rather than absorbing the recoil with his body.

The child's mind is a wonderful thing....Your son probably trusts you and follows your instructions to the letter. You tell him the gun will push him hard, but will not hurt him, so in his mind (and body) he is relaxed and has nothing to fear. My son is the same way treating my 300 Win as a badge of honor rather than some tense dreaded experience.

Hand a 338 to an adult not accustomed to dealing with recoil and observe the body language. Tense, rigid, and the white knuckle grip of death are the norm.

Assuming proper fit and construction once the rifle is mounted correctly 99% of the effect recoil has on the shooter lay between his ears. Fix the mindset and it is surprising just how big a rifle can be managed.

While a fit 6 foot tall 160 pound guy might be the ideal model for recoil absorption, the only thing stopping a 250 pound 5'-8" guy from getting comfortable with a 375H&H is himself.
 
Isn't ADRENALIN a wonderful thing.

I am thrilled that you have a kid that loves to shoot. It doesn't look like I will be so lucky.

However, damage is damage and young kids should not be subjected to hard hits whether it be hockey, football or shooting.

Sorry, but your thought process on this one is pretty flawed.

Jerry

WOW did this thread take a left turn:eek:
I guess if my parenting is to be judged 1 should have the whole picture.
I let me kids do as I did and played in a sandbox with :eek: sand in it.
They both rode bicycles which in a city can be dangerous, both romped in the grass when we went camping in a tent and horrors of hoorors were raised in a big city (thankfully not Toronto) and so far have survived.
We all got some sort of rash from swimming in Lake Okanogan in the summers when we had a cabin there, I guess they could have drowned but didn't.
Both my kids shoot, 1 like me had a bout with lead poisoning from shooting indoors, (that sucked and now we are both wiser) but that did not keep him from playing Lacrosse through out his school years.

When either of my kids wanted to shoot some gun or another I showed them what happened when I shot it and let them make their own decision.

I must be a terrible parent allowing my kids to grow up as I managed to, tree huggers and do gooders be damned.
 
You show some serious ignorance. I can't imagine buying a rifle from you with that thought process.

Lighter mass will move more period. It's a simple law of physics. That amount of movement, a moment of inertia, will most defiantly cause injury to a 100 lb shooter. Whether from the recoil or an impact from accessory items; like scopes etc. Ever see a half moon crescent eye?

Let’s have your test subject of 100lbs shoot my set-up off a bench ( 20 rounds at 300 grs and 2900 fps) and work up some accurate hand loads. How long will it be before they give up? Not too long I lament.

Anyway, I don’t deal with stupidity. Good luck with your synapses.

Shooter

You're being argumentative, and a ####. Magnum eyebrow is caused by being too close to the scope. I've seen guys smacked by a 308 Model 70 when shooting prone because of bad technique. I've also seen guys not touched by the 416 Rigby. Worst I ever saw was a guy get his eyebrow cored out by crawling the stock on a 7mm Weatherby - not a hard kicker in anyone's books. Which brings us to the factors in recoil. You don't mention what "your setup" weighs? Nor (unless I missed it) how it is stocked. I know that Rick's 338 L.Imp. delivers the same bullets you speak of at 3100 FPS (and save the "he's a liar" song. The results are verified and credible). the weight will effect the recoil. If you rifle is a sporter weight rig then, yes, it will kick like a piebald pony. But in a 16-20 lb (or more) rig like Rick builds with a muzzle brake it wouldn't kick nearly as much. I've handled 3 50 BMGs at his place...28 lb, 42 lb and 62 lb. Essentially the same rifle, but which kicks more? Incidentally, Rick's daughter burned through 150 rounds in one of his 50s a few years back, then came looking for more ammo. Not the sign of someone who was punished by the recoil (and for all you guys out there, that's about $1500 worth of ammo - that girl will never be a cheap date - best move along!). Was it because she was slight or because the rifle was built with recoil mitigation in mind?

I think Rick's logic about light weight shooters (like Rick's daughter) versus heavy-weight shooters (like Westicle:p) isn't so much a question of their weight, per se, but the fact that heavier shooters tend to try to "lean into" recoil and soak it up. This causes an increase to felt recoil. If the same shooter stood up and fired the rifle off a standing bench (what they use to test fire double rifles) there would be much less recoil perceived. When I was working up loads for my 416 I started off the bench. Bad idea. 15 rounds of my bench was too much. When I got smart and shot standing with the rifle rested on a round hay bale I perceived much less recoil. There was only possibly a grain difference in the loads (less than 1% of the total charge weight) so the only variable was how much recoil I soaked up trying to stop the rifle in both scenarios.

An interesting anecdote - several years back I bought a #1H in 458 Win and a 1885 in 45-70. I had a big old time working up loads for the 45-70 and shooting the 458. The 45-70 ended up lobbing 418 gr cast bullets at 1950 FPS - brisk from a light rifle like that and the 458 was no pussycat. I didn't think anything of it because the recoil didn't seem to be having an effect on me as my groups were not getting bigger. Then for Christmas my buddy got a Browning A Bolt with the laminated thombhole stock and the BOSS in 223. The first time I got in behind that rifle I had it snugged right into my shoulder and had a good grip on it. When it went off I hardly noticed. It was then I realized that, perhaps, I'd been shooting big rifles a hair too much. I was waiting for the recoil. I knew then, as much as I know now, that the 223 wasn't going to recoil, but subconsciously my body was waiting to get drop-kicked. There's a lot of recoil sensitivity between the ears and that's tough to change. That said, physical recoil can be mitigated.

We're on the same page Jerry.

Some folks need to use their heads for more than hat racks. Physics, theoretical or otherwise, one needs to use their eyes, their mind and some common sense.

I guess you don't know what you don't know. More people need to attend math class rather than puke simplistic anecdotes. And again, used your head for more than a hat rack.

When you’re able to afford the 40 different calibers that I have,mostly custom and ranging from .222 to .470 Nitro, we can speak again about perceived versus free recoil and its effect on the human body.

I bow down to your insults and expansive supply of "mostly custom" rifles. :jerkit:

If you can use math and logic to show me how a rifle weighing "W" lbs, firing a bullet weighing "M" grains at the velocity "V" FPS with a powder charge of "C" grains recoils the same as rifle weighing "W+5" lbs, firing a bullet weighing "M" grains at the velocity "V" FPS with a powder charge of "C" grains, I'll be suitably impressed. Until then you're just a troll looking for an argument.

How about back on topic? The massive rifle collector can start a new thread to school us all on recoil.
 
Rick, it was not my intent to criticise your or anyone elses parenting styles. Unfortunately, my post could be read that way so I do apologise. My bad....

Work = mass X distance. If work (or the energy inputted into a system) is the same, a light weight object WILL be moved a further distance then a heavier object.

The energy put into both objects IS THE SAME, unless we are bending a basic law of physics.

So yes, a lighter person WILL be moved further. There is no way around this unless the rifle leaves the hands of the shooter and puts that recoil energy into flight.

The impact on both shooters will be exactly the same. The perceived effect may be different but I bet a lighter person is going to feel more pain then a heavier person.

If being light was beneficial to dealing with impacts, linebackers would weight 100lbs.

Apparently, they don't...

Jerry
 
Work=massxdistance.

Now yes the work is the same for either a light or heavy person. But does the time of the work change as it takes time for the lighter person to move backwards and absorb the work over the greater distance, where the heavier person absorbs it over a shorter distance and time? Since the recoil velocity for the rifle is likely the same. This would cause a sharper impact to the shoulder of the heavier person.

No back to presicion rifles... anyone make a top notch barrel ready to spin on a savage target action in 338 edge and a 28 - 30 inch length
 
Bomber.. I just bought a Pac-Nor uncontoured 338 edge at 34".. they will do most any contour and length you want.. I haven't been able to shoot it yet but every one else who has had a pac-nor has had good things to say about them...

Talk to Corlanes Sporting goods they can get them quite quickly.. I think I waited only 3 monthes for mine...
 
Thats pretty much what I want but I think I will stay with a 30incher. I just bought a savage LRPV to shoot out and rebarrel. With it`s out of the box accuracy I think it might get a new barrel sooner than later...1.5 - 2moa with several loads tried... Need to find a new bolt head - magnum left hand and then rebarrel to 338 edge.

No, no, no.

Work = Force x Distance

I already spelled this out a while back. The lighter shooter will move farther, but feel a smaller force. The heavier shooter will not move as far and feels a larger force. The recoil is not measured in velocity, but in energy. The energy is the same for each shooter and each moves a different amount, which leaves the force at the shoulder as the dependent variable. It will change dependent upon how much each shooter moves.

Anyone can test this for themselves by shooting a reasonably large caliber rifle off a rest. For the first shot, brace yourself and tense up to resist the recoil. You will feel a significant hit on your shoulder. For the second shot, relax and let the recoil move you, riding it out smoothly. You will feel a much smaller hit on your shoulder. In the one case, you resisted and all of the energy was absorbed over a short distance with a high force. In the second, you let it move and gently absorbed the energy with a smaller force. The same happens to the big/small shooters above.

How each individual deals with recoil and their tolerance for the beating is an entirely different matter.

The physics are irrefutable, the personal tolerance is not. I'm done now, back to .338 rifles.

EDIT - I got all excited about the above and got sucked into it as well. Work is energy per unit of time, so it should be:

Work = Force x Distance / time

We are not talking about work, but energy.

Energy = Force x Distance

The rest above stands, it is just not correct to call it work.

I can offer you both Shilen and McGowen barrels that will fit your needs.

McGowen has the fastest turnaround for these barrels at approx 8 to 10wks.

Visit my website for pricing and all info on specs, contours, etc.

I'm about 100lbs, let me be the test subject. :cheers: (I actually need someone to help me with a physics project at school, if you're near Calgary and have someplace to shoot stuff PM me.)

Here I got these from a physics text...
Through Newton's second law, which states: The acceleration of a body is directly proportional to the net unbalanced force and inversely proportional to the body's mass, a relationship is established between Force (F), Mass (m) and acceleration (a). This is of course a wonderful relation and of immense usefulness. F=MxA

Work is the product of force and the distance over which it moves. Imagine you are pushing a heavy box across the room. The further you move the more work you do! If W is work, F the force and x the distance then.

W = Fx

So..
Actually the total recoil energy (force) the shooter recieves is independent of thier wieght. There is the same amount of force getting to the end of the recoil pad. Now the second law would come into play when talking about the force transfered to your body. I think you would find the acceleration, more specifically the speed of the acceleration to be very important.

Now you could also figure out how many watt`s of energy are created in fireing a rifle by a certain rifle and body wieght and compare them. Since it seems that is what you are trying to calculate.
 
"You'll be within 200 fps (or so) of the standard .338 Lapua and you can of course use a standard LA Remington with no issues. "

You"ll be a damned sight closer then that. I have both, and the 340 Wby is within 50 fps of the Lapua, both from 26" barrels. - dan

Impressive! If that's the case (pardon the pun), I think one can consider this cartridge a very viable option in the .338 cal. game.

The words "Weatherby" and "Tacticool" aren't exactly synonomous, are they?
 
Back to physics (for those interested) ;)

2bad4u2, you are absolutely correct. the larger the mass (person), the more energy (recoil) that system can absorb....PERIOD.

Precisely, which is why:

To absorb the energy, the shooter puts up a resistance (inertia and bracing your muscles against the hit) over a distance (the amount your shoulder/body moves). For all shooters the energy to be absorbed is the same (for the same rifle), so either distance traveled or the force applied to your shoulder must change.

A heavy shooter doesn't move much, so the force applied to his shoulder is high. A light shooter moves more, so the force applied to his shoulder is lower. In both cases the energy absorbed is the same, but the force felt is different.

Jerry,

Work = mass X distance.

Not quite, but it is definetely proportional to the right hand side of the equation; this guy's got it:

Work = Force x Distance

I already spelled this out a while back. The lighter shooter will move farther, but feel a smaller force. The heavier shooter will not move as far and feels a larger force. The recoil is not measured in velocity, but in energy. The energy is the same for each shooter and each moves a different amount, which leaves the force at the shoulder as the dependent variable. It will change dependent upon how much each shooter moves.

The one point of contention is the part in bold, maybe it's not clear from the way you wrote it. We have work (energy) 'W', force 'F', mass 'm', distance 'x' and acceleration 'a'.

a) W = Fx

but F = ma, so:

b) W = max

W is a constant, since we're assuming that the same amount of energy is being introduced into the system of rifle + shooter, both of which have a mass 'm'. Now, changeing shooters will only vary 'm' in b) above, so that leaves the 'ax' factor as the varying one. For a constant 'W', the 'ax' factor will be larger for a lighter person and smaller for a heavier person. Due to Newton's 1st law, the 'x' will be the factor that shrinks, since the heavier object will have a greater tendency to be at rest (due to inertia). In consequence, the deceleration of the shoulder for a heavier, more robust person will take place over a shorter distance, therefore making it perceived as being a stout "punch" versus a lengthy shove, which is the case for someone lighter.

You show some serious ignorance. I can't imagine buying a rifle from you with that thought process.

You came down unnecessarily hard, there. Chill out: it's just a stranger on the Intarwebs.

In any case I hate all of you for being able to play at such long ranges with such big calibers; call it "magnum envy". :evil:

I've gotta move out west... :canadaFlag:
