I'm planning on taking one of my flintlocks on a feral pig hunt in Texas in a few months. I'm currently building a 58 caliber Christian Spring rifle but I don't know if I'll have her done and ready to go in time for the hunt. In case I'm not finished I have two other flints, a 45 Pedersoli and a 40 Late Lancaster that I built a few years ago. I know the 45 would be the default choice of most since it's the larger of the two calibers but I shoot my 40 a whole lot better and it's a lot more accurate. I only shoot PRB's. Does anyone think a 40 prb is too light for feral pigs of around 150 lbs max? I know it'll work with a head shot but would it be sufficient for a heart-lung shot up to about 50 yards if a head shot didn't present itself? I shot one last year with a 45 colt and 280 grain cast semi-wadcutters cast from wheel weights and I emptied the cylinder into him from a tree stand height of about 15' before he went down. That's why I'm asking. They're tough little buggers.
