Against the advice of others I'm going to eventually try to shoot at a mile with a .308.

Using this ammo: http://www.federalpremium.com/products/ ... spx?id=150
This ballistics calculator: http://www.hornady.com/ballistics-resou ... calculator
And inputing these variables:

Ballistic Coefficient: .462
Velocity: 2650
Weight: 168

It gives the following chart:

Range (yards) Velocity (fps) Energy (ft.-lb.) Trajectory (in) Come UP in MOA Come UP in Mils Wind Drift (in) Wind Drift in MOA Wind Drift in Mils

2000 789 232 -3444.4 164.3 47.8 0 0 0


Which says that at 1600 yards the bullet velocity will be 886fps. The trajectory will drop 1721.2 inches, so I'd need to come up 102.7 MOA (29.9 mils).

I came up with the desire to try this after watching the Magpul Dynamics - Art of the Precision Rifle video series.

Please school me on how ridiculous this is.

I'd also love to hear about other peoples experiences with long-distance shooting.

I'm feeling the hardest part might be finding the land to do this. I think I have some friends/family out in the Spokane area that might have property I can use.

EDIT: Stuff you need

Before you buy anything else, please buy and read this:

It will explain why trying to shoot 168gr SMKs, or any .308 for that matter, at a mile is absurd.

I've also seen that magpul video. Puts a lot of things in perspective about calibers, gear,etc and shuts up the Fan boy BS out there. With that being said i say go for it and keep us informed on your progress. I'd like to find a spot where i could do this as well.

Thanks for the recommendation. I checked and it's not in the King County library system. :(

I'm still going to buy ammo and scope/bipod etc. There is nothing wrong with .308 and the rifle and the scopes. I'll also try to shoot as far as possible. I just might not try shooting at a mile very often. :) I'm sure 100 yards is more my distance since that's all my local range reaches out to.

Let start off with a reasonable target size for your attempt; 36" to 48" target should do it. Secondly, you'll need a canted scope base of 40moa or greater. You will also need a reticle which will allow you to holdover for both windage and elevation for the remaining distance and wind hold. Lastly, you will need a spotting scope to spot the splashes so you can walk your shots in.

Wind will be your enemy as at 1-mile so you will also be dealing with spin drift and corrialis effect. Add a Kestrel to your shopping list as well.

Let me know when and where and I'll bring my 338LM and cheer you on,

Bo

THE SHOOTER at the heavy bench rest squinted as he aligned his .45-70 Allin-Springfield Model 1873 Army rifle on the distant target. The rifle fore-stock and barrel was cradled in a rest; the butt was supported by his shoulder. The rear sight was flipped up to its full height, so with no stock support for his head, the rifle tester from Springfield Armory worked carefully to align high rear and low muzzle sight on the speck that was the target - a surveyed 2,500 yards distant.

Holding his breath, he squeezed the 7-pound trigger. The rifle fired, and some 15 seconds later, signals from the target indicated that his shot had struck well inside the 6-foot diameter bullseye on a target well over a mile away!

I'll probably start with a bush as my target as I don't have any targets that large.
I think the bases I was looking at are 30moa. Not enough?
I was thinking for the scope I would go with mil-dot. Good enough?
I have a 22x-66x Celestron 100mm spotting scope with tripod.
I have a 1000 yard range finder so I'll have to do it a couple times for longer distances.
Wind....I don't have a Kestrel. Added it to the shopping list.

Cut and spray paint a sheet of plywood 4'x4' would be good, much better than a bush. 30moa base is not enough. If they made a 80 or 100 moa base that would be ideal but I've not seen anything greater than 40moa. For reticle you'll want something with a "christmas tree" like Horus H59 or Vortex EBR-2 so you dont have to hold over in never-never land.

I'll bring my Bushnell Binos with built-in 1-Mile laser rangefinder.

I'm not convinced that we aren't being trolled, but since the library doesn't stock books that explain what you saw or didn't see in a Magpul propoganda film, give this a read:

http://thearmsguide.com/5348/long-range ... ic-region/

Short version is that anytime the projectile’s velocity falls below Mach 1, results can be unpredictable (bullet may tumble, other badness). Only way to find out is to give it a try.

Of course it's physically possible to hit at that range...I just doubt it's repeatable. ~1600m is way beyond "12in plate all day if I do my part" range with .308.

Curious what rifle and barrel length this attempt will be made with. Might be the difference between "it can be done" and "repeatable performance".

My personal best was a pair of cantaloupes when I lived in Colorado. Winchester Model 70 Classic Sporter, .338WinMag, 200gr Winchester Supreme Ballistic Silvertip, Ballistic Coefficient: 0.414, at the time a Simmons Pro Hunter 50SE was mounted, field elevation 10,060 feet via Kestrel calibrated at work (Air Traffic Control, field elevation known and barometric pressure measured on site by USAF Weather personnel), distance was 503 meters via Bushnell Rangefinder, National Forrest west of Colorado Springs. I don't recall the air temp that day and I lost the little notebook I used to have. There was no appreciable wind and it took 7 shots total to dispatch both melons. Shots were taken from the prone position. It was fun but I haven't pushed beyond 300yds since and that is as far as I can go at Range 15.

Please don't use a 168gr smk. The bullet has issues going transsonic usually somewhere around 600 to 800 yards. It'll do some wacky things after that and your using a g1 bc you need to use a g7 which that bc is .218 litz proven. Also that's a very slow velocity


I'm getting 111.5 moa elevation with a 1900ft density altitude temp of 51 degrees at 2650 fps with a 10 fps extreme spread and a 1/12 twist most standard Remington 700 barrel I've seen you can get a 1/10 which I'd recommend.
Also you'll have true it out because everything is different.


I'm a fan of mills not moa it's just easier to use imho. Very few people I shoot with use moa.

7.62x51 is what I shoot regularly at distance. I have a range behind my property that goes out well beyond 1000 Yards. I have one backstop, and different shooting stations backed off from the backstop. The last 2 spots I have set up are at 750 and 1000 yards. I don't shoot beyond 500 yards much unless it's dead calm but, I have a LEO friend that has a precision .338 bolt with a night force scope of some sort, that stops by once and a while to shoot at 1000 yards. It's amazing what he can do with that rifle. He can whack a 4" steel all day with that rifle at 1000 yards. I shoot the 4" at 500 yards with good results. I do try 1000 yards with my 7.62x51 when he is over. When it's dead calm I can keep them on a 12" target, but it's not dead calm very often, and since we're shooting over the edge of a canyon there's a weird up draft that's really hard to guess. It's weird to have the bullet pushed up and right, and it really shows with the 7.62 at 1000 yards, but that .338 seems to power right through it. It's amazing the difference in the performance. I'm sticking to my 7.62x51 and what it can do, and what I can do. There's not enough time in the week, month, life, to master reloading for and shooting more than one caliber, so I've made my choice for now. I do love to see and watch others that master the longer distances though. As a person who shoots a lot, I really appreciate their level of talent.

It's literally a different world when you get to 1000 yards and beyond, including physical ability and expense.
