From some research on the two above calibers, it would seem that the 338-06 will launch a 225gr. bullet about the same velocity as the 30-06 with a 180gr. bullet. Comparing the bore areas of the two shows the same ratio of areas, so the velocities make sense given the same average chamber pressure.

I would like to know if there is a significant difference in recoil between these two, with the same chamber pressures as above? Seems to me that there should be no difference, because the same average pressure should generate the same recoil pulse either way. So, does that translate into practice in the real world?

Note, I am not concerned about recoil either way, I am just wondering if I am correct on the two being the same.

Thanks,
Mark
 
real world not much difference. my 338 o6 is close to 7lbs, the 30 06 6lbs. both rems 700 two differnt stocks. recoil is sharper in the 06 with 180's than the 338 06 with 225's. in identical rifles i don't think there would be much difference. if your comfortable shooting an 06 the 338 06 would be little differnce. would depend on the rifle and total weight.
 
"For every action an equal and opposite reaction" means that, other factors being more or less equal, launching a 225 grain bullet will produce recoil greater than launching a 180 grainer. However, recoil mathematically measured in ft/lbs is something quite different than subjectively felt recoil. The math too will vary with different weight rifles, angle of stocks, amounts of powder, etc. There's no magic by which you can defy the "equal and opposite reaction" rule. But that doesn't stop you from feeling that you have when you pull the trigger on the right rifle.
 
For the OP, the idea of recoil being similar due to produced pressure isn't sound. An example would be that the 7 SAUM and the 375 RUM are run at nearly identical pressure, but differ extremely in recoil, both in speed and energy.
The .338-06 will kick more. But, I don't believe enough more to ruin your day. With a 7lb rifle your 23ft/lbs vs 30ft/lbs.
 
What rem338win said, but with the same size case. The 338 will produce slightly more energy at the same pressure as the 06. It kicks more. I used to load my improved to almost 4000 ft/lbs.
 
Perhaps physics would indicate the .338-06 recoils more than the .30-06 parent, but felt recoil is different. My .338-06 started out as a .30-06 and doesn't seem to kick any more now. My old Midland .30-06 with it's horrendous stock is way more vicious than my Model 70 Fwt .338-06 in the recoil department.

Felt recoil is dependent on a multitude of things, including firearm weight, pad depth/material, length of pull, stock design, the clothing your wearing, etc. The fact is it is 1ft/sec+ faster, and 33% more recoil given the OP's original post. All things being equal, two identical rifles, side by side, on the bench at the same time, and I am willing to bet that the recoil will be noticeably more. Not likely enough to dissuade anyone from going that route though.
Now if we were comparing a 30-06 with 220gr loads to the 338-06 with 225gr loads, "jetting" comes into play, and the 338-06 would likely feel the lesser.
I personally wouldn't fret, and get the 338-06; its only 8lbs;)

What is "jetting"?
 
I'm using 215 grains in my 338-06 and to me it feels more like a push rather than a kick. It's not as sharp as some of my other guns.

Its a non-technical term to describe the release of hot gas that comes out the end of the barrel after the bullet's seal with the bore is broken. For instance there is more jetting with a 300 Weatherby and 200gr bullets than a 340 Weatherby and 200gr bullets due to the smaller bore size. This creates sharper muzzle rise and faster recoil (not stronger). It also makes it louder. Of course this is semi-theoretical, as all things again need to be equal.
Jetting does seem to have an effect on the felt recoil of a rifle. Kind of why everyone says the ol' H&H pushes more than slaps like smaller bore with the same cartridge.

I think this is the answer I was looking for, thanks Rem338Win. As I said, I am not worried about recoil either way, but was trying to wrap my head around the recoil differences between the two rounds based on the same case.

Everything in life is logical, and can be figured out with a good does of common sense. Except women; their lack of logic borders on supernatural. I would like a 338-06 with 210gr TTSX's at 2800fps. That's a super elk round.
 
For me, my Tikka T3 LS 270WSM shooting reloads of 140gr Accubonds has "MORE FELT" recoil than my Sako m75 Greywolf 338-06AI shooting 225gr Accubonds. I can say the Sako does weighs more. Compared to my Sako m75ss 300WM with 180gr Accubond reloads, the 300M has more "FELT RECOIL"

Just my 2 cents. I dont have a 30-06 to compare.

How is the accuracy and velocity with those Accubonds? Still thinking a 338 Scovill in a 7lb all up rifle is the ticket for mountain elk hunting.
 
In as nearly identical 7600's as is possible, the 35 Whelen with 225 grain loads has more preceived recoil (to me, at least) than does the 30-06 with 180 grain loads. IMHO, it is not "significantly" more, but more nonetheless.
 
To my thoughts, if you launch a 225 gr projectile with say 60 grains of powder, and then you launch a 180 with the same amount of powder, The 225 will generate roughly 25% more recoil pulse back to you as thats roughly the weight increase. Minus the fact that the 225 gr base is bigger , so it has more surface area to push on, making launch more efficient , therefore even though its a heavier bullet, it can reach near same muzzle velocities. I am a total moron in ballistics, this is just my convoluted take on it. Please correct me if I'm WAY off base. I assumed it would be similar to my lines of thinking, if all other things were the same. (case, powder, primer, etc, only difference being the bullet diameter and weight.)
 
rem338win,

Accuracy for me are 0.5" groups with both the TTSX and Accubonds. I know my rifle is no light weight at 7 pounds. If I remember correctly, my Sako m75 Greywolf 338-06AI with scope wighs in at 9.6 lbs. The new Pac Nor barrel is cut to 24" and is a Sporter #5 contour, super-match grade stainless fluted/powdercoated barrel.

Sgt., you are correct. I was having a brain fart when I asked the question. If both bullets have the same muzzle velocity, the 225gr. will have 25% more energy, so it should produce ~25% more recoil.

my .338-06 had a very slight increase in recoil over my .30-06. 225gr @ 2650fps.

Exactly. We are talking 25-30% more than 22ft/lbs. It isn't going to loosen teeth. Now if we are talking 25-30% more than that generated by a .340 Weatherby.....


And thanks for the answer MP. That is a fat tube on that gun.
