I collect Contenders, & currently have 5 actions, & a pretty good selections of factory barrels in most available calibers...
often the 45-70 Contenders come up, when talking major recoil, & I usually respond how much I like shooting my 45-70, & my most violent Contender is hands down the factory 14" 375 Winchester barrel with no compensator...
... well, I was flipping through some load books while sitting on the "reading throne" the other day, & noticed that a good share of the hotter 375 Winchester loads fell into the same CUP ratings, as the "modern rifle only" 45-70 loads at around 50,000 CUP...
my concern, is that even though that is an older factory 375 barrel, is the Contender really safe for long term use with the 375 Winchester ??? my understanding is that hotter 45-70 loads can stretch the frames of the Contenders, I'd think 50,000 CUP loads in 375 inchester would easily be in the same boat ??? I've probably only put 100 or so rounds down rthe 375 pipe since I got it, but was planning on loading 35 Winchester next year... curious on your thoughts as to how hot is safe in that cartridge for long term use ????
