Nomercy

I'm not really certain why everyone always assumes that these big bullets don't expand, it's basically only because people choose harder bullets when they've got a bigger starting diameter. I typically use a medium-hard cast flat point bullet in .45-70, believe me, the bullets expand quite a bit...however, 45cal is big enough you don't need them to expand much to do a lot of damage to a deer--I've recovered a jacketed HP that expanded to nearly an inch in diameter in a deer.

I guess I'm saying that their expansion is a function of their design, not of their caliber.
