I'm sure that'll be thrown around being it's a SA cartridge. I think the 270WSM would work in a SA using the heavy .257 bullets. It's case capacity offers more than the 6.8 western case does. Haven't done the measurements but almost have to think that it will work in a SA mag. The 165 AB(.277) bullets are over 1.5" long. The 131(.257) run around 1.4". Ogive measurement means more but I don't have those measurements.How about a 25 Western?![]()
