Re: AI AE Covert
Smchop,
I published some of the first shots in my AI/AE Covert here:
http://www.snipershide.com/forum/ubbthre...313#Post2632313
I have since put 300 rounds down range (5,280 ft msl) and this is what I have found:
1.) The folks a MileHigh Shooting are a great bunch and outstanding to work with (too bad I live three miles away - its expensive).
2.) The gun does the following with factory ammo:
168gr FGMM - 2,470fps gives .3 - .6 MOA accuracy
175gr FCMM - 2,385fps gives .2 - .5 MOA accuracy
173gr M118 - 2,443fps gives .6 - .8 MOA accuracy (did the chrono read too high?)
3.) The gun likes 175's better than 168's and these better than 155's although you are kind of splitting hairs between the 168 and 175's.
4.) Stacy has some great data to get you started on sub-sonic load development but I found that his loads were "hot" launching bullets at 1,085+ fps (just super sonic here at 5,280msl) causing the bullets to go transonic and wobble at 100 yards.
With respect sub sonic loads:
i. Its more challenging than full power loads and perhaps more fun.
ii. Hornady 225gr Match or 220gr SMK bullets do not quite stabilize at sub-sonic speeds.
iii. Due to the shorter length, the gun does stabilize 220gr hornady round nose and they shoot really well (1" or less at 100 yards).
iv. Trailboss works MUCH better than unique
v. CC 350 magnum pistol primers work MUCH better than Fed 210m primers
vi. 208gr AMAX look like they will work really well (more testing needed)
5. All of my 308 Match loads have shot under 1/2 MOA in the gun except my 155gr loads which shoot .7 - 1 MOA.
Summary: The gun feeds flawlessly, has a nice balance (w/the can attached), and shoots everything well (except 220-225gr sub-sonic match bullets)
have fun ... good shooting ...
