I dunno' Spitty, I had an 1894CS in .357 mag and it was an excellent carbine. I also had two .45/70's, an 1895 Limited and an 1895 SS and they were both excellent. I haven't looked into the 336 and didn't know about the .44 mag problems.
I was very happy with all three rifles. Maybe stick with a '94 for .44 mag and go .30-30 with a 336 to avoid potential problems.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen. ― Samuel Adams
