I'm thinking about rebarreling my 223 1/9 to a 223 AI 1/8. I've got 12# of H322 left and want to try and use it for heavy for caliber bullets such as the Hornady 75gr HPBT.

The H322 works REALLY well with the Hornady 50gr Z-Max, but am curious as to what I should expect with heavier bullets. If it doesn't do well, I still have Varget for the heavier bullets, but I want to try and use up the 12# of H322.<!-- google_ad_section_end -->
