I've heard rems. blow by issue.However I like they claim of a magnum gun.Can ruger withstand the same potent loads?Or is that a rem. only feature?Thanks

I have a ruger77/50 and it says up to 120 grs powder.If you want a maguman muzzle loader get a savage ML11.They will shoot black powder subs and smokeless very well.

Thanks Owensby,I'll look at them.

Savage is the way to go
