I have yet to shoot this particular rifle at 1,000 yards... i will get back to you with the results as soon as possible. Looking at the 100 yard data on this rifle... and looking at 100 yard data on similar rifles i own and there data... im guestimating i will acheave around 10 inch groups @ 1,000. Now all i need to do is call up my friend and have him load me some 100gr .223 ammo :)

It should... the other AR-15 i use 100gr ammo in is a 1-7 and im getting just over 10 inch groups at 1,000 yards on a no wind day. A friend of mine uses a 1-7 but with 8 groove rifling instead of 5 like i use... and he uses the same ammo (infact he is the one who makes the 100gr ammo for me) and he is getting just below 10 inch groups on a no wind day at 1,000 yards.

Keep in mind the 100gr .223 load has such a high BC that the super to sub sonic transition wont affect it that much... if at all. PRL 87gr HPBT Match bullets seem to work great as well... but they only come in moly... and i dont use moly coated bullets. 77gr SMK's work fine but i wouldnt use them out past 800 yards. 77gr Noslers work fine for semi auto's as well... but it has a canellure and im not a huge fan of canellured match bullets. Another thing... when using 100gr ammo in a .223 AR-15 you have to sink your front post sight all the way and have your rear sight all the way up just to be in the basic area of the target. Zeroing an iron sight rifle at 1,000 yards is really a pain in the *SS... it took me over 100 rounds to zero in my other 1,000 yard AR-15 over a time span of 2 weeks. :? I have a pic of the BH 100gr bullet on my site.. here is the link. Oh yea... BEWARE OF THE SOUND FILE WHEN THE PAGE OPENS... :wink: http://www.geocities.com/expert_riflema ... 23two.html . You can clearly see the 100gr BH bullet does not even have a boat tail design... this is because the bullet its self is so long that the rear of the bullet slowly pulls the "air bubble" created by the nose back towards the centerline of the resistance point... thus full filling the purpose of the boat tail with out having a boat tail present.

Oh yea... the 5th question down on the 3rd page has to deal with twist rates and what happens when you use to heavy of a bullet in to slow a twist... Ive seen 5.56 tracers fired out of a 1-14" twist M-16 and it will go about 75 to 80 yards and then dramatically take a 20 degree turn and go flying in random directions... not very safe.

BC, I think you will be good out 1000 with Irons. I would like to shoot my Match Garand that far some time, but in OH the facilities with that distance are very limited. Perry is the only one I know of off the top of my head, and it is kind of hard to get in there.

Isnt there any BLM land or otherwise open area with a hill for a backstop that is legal to shoot on? Thats what i did when i was younger with my friends... we would go out to the desert or the salt flats and shoot 1,000 yards with out springfield 03's, M-1's and huntin rifles... then as time... age... and most importantly... MONEY... progressed; we started getting better rifles. Thats where i learned to shoot 1,000 yard iron sights. 55 gallon oil drums filled with sand / dirt work great as targets. We would usually stack them 2 high and 5 wide. Make sure to stack the top drums uptop the bottom ones before filling the top ones... there pretty hard to stack up when there full. :lol:

re

Even with using a competition sling for a support and whatever special gloves you use, getting 10 inch groups at 1000 yards with iron sights is nothing short of a miracle in my mind - to do that you must have the eyes of a hawk.

At 3-400m's the torso target is half the width of the foresight, at 1,000 yards it must be under a quarter of the width I would assume - being able to keep the exact same point of aim at that distance and keeping the rifle that still really is amazing.

I dont use standard sights... KNS .034" Square A2 Front Sight Post... Bushmaster .036" Super Match Competition Rear Sight. The front sight looks like a needle... and the rear peep sight looks like a needle couldnt fit through it. :)

All the same, you must have good eyes.

With my eyes and hands I am pushed to get 100mm groups at 100m's.

Amen on the sights BC, My match sights are real nice, set up by the USAMU that built the rifle for my Great uncle when he retired from the unit. This part of Ohio is so urbanized that we are very happy to get a 500m Range and that is GOVT owned on a DOE facility and very hard to get into. I have fired 600 at Perry, and the target was not as hard to see as I thought it would be. The only sling we could use was a 1907sling or web sling. The 600 was prone position slow fire fire single round feed. I was so gratful to the Marine Team as they let me borrow a spotting scope so I could see the markers after each shot. It was my first match, first time firing 600, and 3rd time firing the rifle, so when I fore my best string of the day at 600 I was happy.

Do you go to Perry every year now? Or was it just that one time? How far is Perry from your home?

I will be there this year, with more practice, so I can be more respectable I hope, the first time was last year, and what a learning curve. I had none of the right equipment, but everybody was helpful and now I am hooked. Perry is about 1.5 to 2 hrs away, so it takes a lot to stay away form the North Store at CMP. I will compete in the Presidents Match, and boththe Garand and Springfield Matches time off from work permitting.
