Thin jackets, light bullets, hornady xtip, and Sierra has a new hollowpoint out now but I can't remember the weight, it's a lead nosed hollowpoint, I can't wait to get ahold of some but they're supposed to expand more reliably than traditional hp, of course if they're too heavy..... I think with the right shot wadcutters should work, I remember takin a woodchuck with a .36 percussion revolver and left skull and brain matter EVERYWHERE!
