[QUOTE="25WSM, post: 2100051, member: 38048"] As per post 48. Redding is saying their 280ai is different than a 280rem imp. 2 different cartridges. An improved can be any length you want. An AI is specifically made .004 short of parent cartridge. Post 49. I never said any Reamer prints we're wrong. I said gunsmiths don't chamber to the numbers on them. We use Sammi spec guages to make a chamber the correct depth. So if I'm using a Sammi spec 280ai guage and a standard 280 go guage as a no go and they both give me the same depth than I conclude it's the same chamber. The Reamer is cut the same and it's the same depth in the barrel. The intent of making the chamber .004 shorter from Ackley was so parent brass would have a crush fit and be easier to fireform. Now if nosler made the chamber another .014 shorter that's .018 shorter than parent brass. A standard 280 brass would never fit in a nosler chamber. Yet they do fit with a slight crush fit. Just like the Ackley is supposed to. Shep [/QUOTE]
