Default M1, 1000 yds: some help please

There is a 1000 yd match coming up at Quantico. I would like to try my M1 in that match. Any idea how many clicks of elevation I am going to have to dial up on that rear sight for this. I am up 12 clicks for 200 yds for SR target: 6 o'clock hold with POI at Ten ring from a rest.

Its a CMP match so I assume that target can be seen without a scope??

No, not trying to light the world afire but I am trying to see how well I can do at that distance if the M1 has the legs for it.

Any help would be very much appreciated

You can see the target and all of those to your left and right. I personally have a hard time reading my number board without a scope. The scoring disc and spotter are 6 inches. I can't see those at all at 1000yds without a scope.

You can use a ballistics calculator such as

But you will also need to know what bullet you ar using and the velocity at a given point.

I plugged in a 175 gr smk and 2600 fps. I think each click on an M1 is 1 MOA? If so, you need to come up 38 more clicks(or 38 MOA) for 1000 yds.

Edit: Keep in mind you want stay super sonic to target and this drops below super sonic at 1100 yds.

Dave, you are light years ahead of me as I am just wandering into this type of match. I have LC 69 ball from CMP. I assume that is 150 grains and unk. velocity.

I may not be able sort this out without a practice session and have postpone going to that match till then.

The first time I shot 1,000 yards, one the shooters told me to start at 20 more clicks that I had on at 600 yards. I ended up going 22 more than the 600 yard elevation...if that helps any. You do get sighters, so that will help.

When I shot my Garand at 1,000 or my M1a for that matter I have a hard time getting a good check weld because the rear sight is so high. Its almost like shooting a chin gun. I plan on setting up a 1000 gun with the front sight ground down so I don't need so many clicks on the rear sight. Bu that project is low on the list right now.

I'm glad you posted this. I had been wondering about the Hornady match out to 1000, but never thought about it when I was at my computer.

Here is a link that gives you the basic info out to 1000.

http://www.hornady.com/images/sell_s...match_ammo.pdf

I shot this ammo at the eastern games and I'm very pleased with it's performance. It's very accurate and very repeatable. You can get it from the CMP store, Midway and Cheaper Than Dirt.

According to their lit. The round is still supersonic at 1000 and shows 336.9" of drop between a 200 yard zero and 100. That's a ~34 click correction. If you are holding six o'clock at 200 on an SR at 10 ring POI (assuming the bottom of the ring) Then you are about 3 clicks high for POA=POI. I would factor that into my comeups and shoot POA to center of target at 1000 and see where you are on the paper. If your POI=POA there you can correct back to a 6 o'clock hold with 2 more clicks up (20" on a 44" bull at 1000) and hold the bottom of the black.

HTH and good luck with your shoot!

Gents,

I won't have access to a range before the match except for a 100 yd range and I think what you are telling me is I am wasting my time thinking I can factor X amount of clicks on data for 100 and be printing on target at 1000 and I also take it that since I had intended to shoot LC 69 ball, that I got more problems entering this since I don't have a mega powered custom load developed for 1000 yds.

I sure would like to shoot 1000 but I am being swayed now to back down and work up to this longer range after more range time. I don't want to go
out there and not have a chance of hitting paper and just fly rounds thru the
airspace over Quantico for nor results. I am good with marginal performance as this is not a NM Garand nor shooting match grade ammo , but I am not keen on shooting and having blank results.

I may be leaping ahead of myself trying to get into this 1000 yd match opportunity next week.

I would just go and shoot. How else are you going to get the experience? It will be more challenging with LC69 ball than a more consistent load but why wait?
I have never shot at 1000 but I have shot at 600 XTC alot. I used the Ballistics calculator and was in the black on my first shot.
I have never chronoed lc69 but I have HXP and it all runs around 2700fps.
Plug it in to the calculator and see how many clicks up you are if not on paper I bet you are close.
Good luck
Dave

Edit: I ran the calcs at 150 gr hornady FMJBT at 2700fps. It says 40.3 moa drop but it is also dropping below super sonic at 1000yds. Come up 40-41 clicks and see what happens. Most folks will shoot a heavier bullet than 150 grs. at long range it will stay super sonic longer.
