This data is totally UNSAFE for anybody to use.
Do NOT use this data under any circumstance.
It is totally safe in my gun, but NOT IN YOURS.
REPEAT, DO NOT USE THIS DATA.... so endeth my CYA. Thank You for your attention.
VERY EARLY TESTING... Cheap GM barrel on a Remington 700 action (100 yards (smallest dots are 3/4" for scale)).
Temporary 1.2-6 Minox ZA power scope.
Final numbers for 200gr (AA2520 and AR Comp) and 270gr with AA2520
The 200gr likes the 2520, 49.5gr getting 2575fps avg.... Right most group at 100yds.
270gr with AA2520 was not as good as the AR Comp (top group was 39gr at 1920fps). I believe this is a case volume issue due to the larger bullets.
Bottom line:
1. AR Comp for heavier bullets >235gr, AA2520 for lighter bullets.
2. Still some headroom (not much in the light bullets with 2520 (still not 100% case capacity)
2. Fire-forming makes no difference in performance.
BTW the 200gr at 2575fps with AA2520 .5 MOA on a temp 6X scope, at higher power may tighten up (oh yeah).
This data is totally UNSAFE for anybody to use.
