I also have a Genesis that I just bought on sale at Cabela's. I like mine. I have not messed around with loads, just started with 100 gr Pyrodex RS and a Hornady FPB and got acceptable hunting accuracy. My groups (all 2 of them) were1" at 50 yds.FPBs are copper-jacketed, hollow-based, full-bore conicals that weigh 350 gr. No sabot is used. I've shot 2 deer with them so far and they have performed well for me.

Messing around on a ballistics calculator, and looking at load data from Hornady on their FPB bullet, I found that if you use 120 grains of powder you'll get about 1500 fps. Sight the gun to hit about 2" high at 50 and you'll have a 150 yd load. High point is at 75 yds I think, where it was 2.5" high. Zero was at 125, and it was 3.5 low at 150.

IfI were you I'd get me some FPBs for hunting. They are pricey though, so not a great choice for recreational shooting.
