I bought a new 45-70 today along with some 405 grain remington sp ammo,and this ammo can only seem to penetrate about half of what I can do with hard cast in a hot load in my 45 colt levergun!!!.I was only shooting into 2x4's but this load only shot through 4 damned 2x4's!!!Not very impressive for a supposedly bear defense gun.Must be loaded very light and did not have noticeable recoil.
