I been killin' pigs with 35 fpe? How is that possible?
You practise the best method of hunting. You ignore everything that's written by anyone who claims to have knowledge of mathematics, ballistics, physics and hydraulics.
You shoot some thing with a small, hard thing that penetrates soft, vital things. The 'going in' thing makes a booboo which causes a leak. Sometimes, it's a big leak and other times, not, but you always hope for a big leak.
Well done!
P.S. It makes no difference if the small, hard thing is made of galena or pennies. It just has to make a wet enough booboo.
