Re: BC of Hornady 178 BTHP
I assume you're talking about the A-max, right? I just picked a few boxes and am going to work up a load for my AR10. I read great things about them and am optimistic. My barrel is 1:10 and 20" long. I'm starting at 42gr of Varget & working up from there using LC brass. I should have some results over the next week or two.
