Cast Performance 45/70 loads

[daddywpb]

I've been looking for a good heavy bullet hunting load for a Marlin 1895G 45/70. Looking at Cast Performance's selection of WFNGC bullets in 300, 400 and 460 grains.

My questions are: Will these loads cause severe leading problems in my Ballard type rifled barrel? Would I be better of sticking with jacketed bullets in the same weight class?

I'd appreciate any comments on leading problems and accuracy from someone who has used these cast bullets for hunting.

I currently use a Cast Performance 300 grain LFNGC bullet in my Ruger Bisley for hunting hogs and deer. I have not had any problems with leading with that load, but the 45/70's increased velocity has me concerned.
Thanks.

My load, work up to it!  A 440 WFN with 50 grs. of H-322.  Clocks 1800 fps. out of an 1895G guide gun.  This a hand cast wheel weight bullet with Lyman Moly lube.  This does not lead at all that I can see. I have shot CP's bullets to almost 1400 fps. with no leading problems.  If the extra speed causes difficulties, cast your own!.  This load shoots around 1/2" at 50 yds.,  I have shot a Russian boar with a WFN out of a .475 at 1350 fps. and the visible internal damage was notably greater than any of the jacketed bullet boars shot the same weekend.  Not much of a test, but the damage from a non-expanding WFN bullet was impressive!  Good luck.

They won't lead if they fit properly. Stick to the 400 grainers for best accuracy. Remember this 45-70 will kill things just fine at black powder speeds. You don't have to get carried away trying to make a .458 out of it. Yes, you can do that with several powders but it's just not needed or desirable for long life of your rifle or your shoulder.
