I'll add my 2 cents here, as I think this is a fun project. I've loaded 405g bullets in my 45/70 with 12g of trailboss and 300g jacketed with 14g. The 300's go about 1200fps and the 405's are right around 950fps. I wouldn't want to get hit with either one. The 300's group 1.5" at 100y!!
Now this is out of a GG with the ported barrel, so she ain't quiet at the best of times....but it's no louder then a .22RF. So if you where to try a 500g bullet, you could get about what?...800fps maybe. Reduce the charge a little and your at 600fps. Now I'm talking out of my a$$ here, I haven't tried going that low, but sure seems feasible. Add in a long barrel and I'll bet that would be much more quiet then my ported short barrel. Might not be 300fps there CC, but I'm betting 600fps is easily doable.
