so here's the scoop after hearing how using 4f goex in my 51' navy colt 36 caliber replica by pietta would blow the gun up, I started out with 20grs of 4f goex and it didn't with a lubed wad really get the ball against the charge very good so that one load was weak! now the next load and mind you I was only loading one charge in the cylinder at a time and so I went up to 25grs 4f goex and 1/8th inch lubed wad and it had some okay power as a target load! but wasn't satisfied so I went up to 30grs 4f goex and now with a 1/8th inch lubed wad and roundball now this load wad all the cylinder could hold and had to push the ball in pretty hard but cleared the chamber mouth and so with this load I was very impressed as it has even more power with 30grs 4f over 30grs of 3f goex and shoots very strong and accuracy was even better and cleaner burning! so I decided to load all six with this max load and didn't have any trouble! so I really like the goex 4f at 30grs measured with a pistol measure leveled as the cylinders can't hold any more than that! but yeah my pistol survived and performed very well and so I can't see why it couldn't take care of hogs with this max load!!
