I'm gonna try loading 178 BTHP's in some new Hornady Match brass. I've been using Lapua. Wanna start using some Hornady now, see how it compares. I have IMR4064 and 8208XBR to play with. Would the 4064 push the 178 better than the 8208? I thought somebody somewhere told me the 8208 was better with lighter bullets. 168 or 155? Thanks for any help. That's why I love this forum.
