I don't reload...yet.
I've been religiously shooting .308 Federal 168 and 175 smk match and have been happy with the results.
This weekend I drug the chrono out again to check out some Black Hills Gold, 168 Hornady A-Max match.
I shot 5 rounds each of the Black Hills 168 and Federal 175 smk. The Federal was an average of 2583 fps with a spread of 19 fps between the fastest and slowest rounds. That's pretty consistent with what I've seen previously. The Black Hills had an average of 2539 fps, but what I found surprising was a spread of 108 fps between the fastest and slowest rounds. Is that difference normal with match grade factory ammo?
I'm pretty sure it's not acceptable. At 500yds that's a difference of .3 mil or 6.5 inches of drop.
Before I call Black Hills all irritated, I wanted to see if I'm being unreasonable or have unrealistic expectations.
Any input is greatly appreciated.
