308 to a mile?? Using a Savage model 12 F-TR

Tigrr let me know what your friend thinks about the bullets. I was considering calling him too. I do have to say though when I punch the numbers with a 155 gr at 3000 it says 105moa defiantly workable.
 
308 to a Mile?

Scopes and tapered bases make this possible, not easy. Hitting a mile with peep sights would be a challenge and worth trying. Hate walking away a total loser, a "good" backup gun will ride along.

Now its time to calculate how much front tunnel rise to use. That requires a using a portion of my brain that's been dormant for years. Anyone with pointers on long range "irons" calculations please reply.
 
Ya mean we can use our 303 with that stand up site with 1300 yard hash marks on it(no 2000 yard mark). Oh now I've got more reloading to do. Now I have to cast bullets too. I use IMR 700X for my 303!!
For just using the irons I don't think the trees behind the backstop are tall enough. Matbe 75 ft tall trees. we will see how far the 303 will reach.
A little hail Mary will be in order. I have to find a warm shop to paint the target before the shoot. Its still full of marks from the sept shoot.
The new unfired Savage is finally getting out of the safe. I guess I should clean it.
48 grains of IMR 4064 behind a 155gr bullet and have at it. LIG

Shooting a .308 at a mile sounds most worthy, I hope you guys have a great time doing it.

Option 1, if you have an existing 12-twist or 13-twist 30" barrel target rifle is to shoot a topnotch 155 target bullet (Lapua Scenar, or Berger 155.5 Fullbore) at the typical 3000 fps

Option 2 would be to to use a 1-10" twist 30" barrel with a long throat and shoot Berger 230 Hybrids at the equivalent-energy speed of 2466fps.

With the rifle zeroed at 100 yards, at 1760 yards you need 101.5MOA of elevation for the 155.5@3000 and you need 95MOA of elevation for the 230H@2466. So make sure you have a good hundred minutes up from your 100 zero and you'll be fine. Speed on-target at 1760 yards is 875fps for the 155.5s and 997fps for the 230Hs

Shooting with iron sights would be straightforward. The standard aiming mark size for 1000 yard shooting is a black circle 48" in diameter. Making an 84" circle (7 feet diameter) at 1760 yards would provide an equivalent sight picture.

Note that for both iron sights and scope, you do not need to aim at the target itself. If the terrain allows it, you could set up an aiming mark above the target. For example if the 1760 impact point is on the face of a hill and you could find or make an aiming point that was 100' higher up, you could aim at that and you'd only need to add in which case you'd only need to have about 30MOA (over your 100yd zero) on your sights.

If tigrr could arrange for a convenient aiming mark 60-80 MOA above the target then nobody would have to do anything special to their sights in order to come out and shoot this.

If Tigrr would set 96" black circles 30' over that row of trees behind his one mile target .... just saying. Or we could rent a blimp.
 
Hmmm 303 to a mile... Looks like I have some work to do also. According to my calculations if you can get a 174 to 2500fps it will be 140 moa or 213 feet of drop. 2500 fps should be possible. Well there is only one way to find out.
 
interesting topic for sure, one thought that comes to mind is using the matrix 210 VLD, i myself have not tried them, but they list a very high BC(G1) of .7525, now i plunked that into my ballistic calculator(shooter, android based) at 2550fps and came up with 89.2 MOA up (200 yard zero), arrives at 1042 fps in 3.5 seconds, about 100 fps faster than 208 amax and almost 20 moa less drop under same MV, just my .02

What ballistics calculator is used out to a mile?

+1 on the JBM recommendation, especially if:
  • you use a G7 ballistic coefficient, or
  • the bullet you are interested in shooting is in the JBM library and has a suffix "(Litz)" (this means that JBM has available the G7 b.c. info from Bryan Litz's book Applied Ballistics for Long Range Rifle Shooting

Thanx for this info. Was looking at the Savage Target models. I have a Benchrest model but its set up for 1,000 yards only. The target models have a 1 in 12. Nothing with a 1 in 10 jumps out at me.
 
If you copied the IMR 4064 loads I had here don't use it. The primer blew out of the RP brass and knocked the ejector out so I couldn't get the bolt out. I pulled all the bullets.
The bullets I am using for this 308 to a mile consist of
Nosler CC;s 155 gr.
Chinchaga 176 gr RBT ULD ST,
Chinchaga 205 gr RBT ULD ST,
I'm using IMR 4064, I know R17 would be better for the heavies, but its a 3 hour drive to get it. I have 24lbs of 4064!! Reloading starts today.
They will all be loaded just shy of primer flattening. Group size well its a mile!! Lets get it there first.
All these recipes are taken from Hornady, Nosler, Lee and Steves reloading pages. I wished Jerry and Henry lived closer, then again I'd be broke. I like to try all sorts of weights but budget restraints come to play. LIG
The test loads(all were pulled and starting over) RP brass = less capacity or something, blew out the primer. Started with 10% less, too. Square one again.

The rifle is ready, including the cardboard under the cheek rest to bring it up to the new scope level. It will be broke in as I shoot. Shoot once clean X5, shoot 5 clean X3, then shoot 100 more. Thats my way

The ammo is ready, I even used CCI BR2 primers, I must be nutzzz.

The target is painted

Soon.
 
Tell us more about those Chinchaga bullets, this is the first I have ever heard that name. I assume they are the pretty-looking ones with missile nosecones? How much do they cost, what is their claimed BC, what does the boattail look like, yadda yadda....

12 twist will get you to a mile easily. Just find some Amax bullets. They all seem to fly subsonic without issue.

Some of the lighter bullets up to 200gr (maybe 210) will work in a 12 twist so you have tons of choices.

It all will fall like a stone and drift like a leaf BUT they will get out there.

I thought I had put this in a previous post but for those that want to shoot but do not have the scope elevation, just use a 2X4......

Take a 10ft 2X4 and bury it in the ground (2') 100yds away from you. This leaves the top of at 96" or 96MOA (give or take). Aim at the top of the 'stick' and off it goes to a mile (give or take). You can dial the rest.

You can put marks along the 2X4 every foot for intermediate distances.

Simple.

Oh ya great now theres going to be 10 2X4s standing out at 100. Jerry volunteered to come dig the holes in the frozen dirt, 2 feet down!! Its only frozen for the first foot.
Tell me this after I did all that work setting a scope on my gun. You have 2.5 - 3 seconds to rip your eye over to your spotting scope to see impacts.
Now that has potential for the iron site shooters with spotters. Hmmm. 303 to a mile!!
This should be good. Might need a 12 foot 2x4.
