I think the best modification to save detents is to groove the bolt all the way around. I think it wasn't done from the start because the flat on the bottom for mag rounds but I don't think it will hurt anything. Once we can get spare parts i'm gonna try it out.
Played a few games with my hammer today. I found it hard to aim with the back bottle asa gonna try to get a bottomline for it . Also I have a 14" trinity barrel that is rifled with a .687" bore wasn't much difference between normal paint and FSR on the chrono
