I bought two bank bags of empty cases and had a mix of 223, 40, 45 and even I think 15 454 casul cases. My qquestion is , could these 454s be trimmed to long colt lenght and be used in a long colt cylinder, succesfully?
Kinda sounds like more trouble than it's worth to me. I'm pretty sure 454 Casul cases take "small rifle" primers, not "large pistol" primers like 45 Colt cases.
