Well I got to shootit this weekend; however only shot it 8 times. The weather was closing in and it was getting dark. No real data on regulation yet, I didn't have a bench to rest on so my shots were standing off hand..and pretty crappy. They all hit the target at about 30 yrds. I started at 80 grains of pyrodex ffg and worked up to 130 with not ill effects noticed. The kick is quite mild I think, just a big push. I've shot 458 and 45-70's in really light guns, they were painful, this thing is quite delightful compared. One thing is for sure, it makes a really BIG hole on the target and backing bank.
