I started at 58 grns and it was pretty good but I kept working my way up and when I hit 60.5grns it was like flipping a switch. Just glad I finally found something it likes. I was working up trying to see where I would find pressure signs but I’m not going any higher. Hogdon shows 62 gr as max but the 60.5 gr fits in the case without having to be compressed and giving me complete case fill.
