I would like to get a Marlin 1895 SBL for hunting big game in the thickets. I use hard cast bullets in my Ruger Bisley 45 Colt and would figure on doing the same in the Marlin.

In the Marlin what Brinell hardness does one typically need to prevent leading with 1800- 2100 fps velocities? Do you need to have a gas checked bullet? Many are bevel based and I am pretty sure that I would not want that. I think most likely I would use a 400 to 425 grain bullet but may consider a 350 grain bullet. I like a large diameter meplat for putting the smack down on the critter, so preferably in the 0.32" or larger range for meplat.

I have done some searching but so far have not found any decent 350 grain bullets that would meet my desires. Any advice from you all? Thanks, Rufous.
