What type of ammo do you use in your AR15's. I have a 18" long Cold Hammer Forged barrel with a 1:7 twist rate and am trying many different types of ammo in 223 or 5.56.
Right now I'm trying to shoot some of the Army Surplus M855 62 gr green tip ammo in 5.56. I'm having trouble with many variables and my groups are not tight at all. They are all over the place at 200 yards.
I've tried some Winchester 75 Gr bullets, Hornady Match Grade 75 gr bullets, and of course a lot of Ammo in the 5.56 55 gr FMJ type bullets.
I'm thinking that maybe the heavier bullets will shoot more precisely once I get the optics sighted in properly and break out the lead sled again. Trying to shoot at 200 yards off a shooting bag is hit and miss and I'm not that steady of a shot. And I was using an EXPS3-4 EOTech the last couple of times out at the rifle range and having trouble adjusting the windage and elevation on this puppy. I've never had to adjust it so much in the past. But I'm thinking that temperature extremes while it was in storage have caused the zero to change and the windage and elevation controls to malfunction somehow. It took me forever the last time out and lots of ammo to finally start hitting the bulls eye again.
