[QUOTE="25WSM, post: 2099135, member: 38048"] I'm not getting into arguments about this anymore. But if you use the exact same headspace guage for both then how can it be any different? Swamphinter have you measured the shoulder length of each cartridge from your 2 rifles. If one chamber was cut minimum and the other max they are still within spec but no way the one fired in the max chamber will fit in the minimum one. A 280ai is a 280ai. The original and the Sammi are the same. 280improved or 280rem imp can mean anything. But a true Ackley chamber and the Sammi chamber are the same. I do all my 280ai Chambers the same as Ackley did and the nosler brass fits perfect. If you want to believe that they are different go ahead it won't hurt my feelings any. The .014 difference is only there because they are measured at 2 different spots on the neck. Ackley measured different than Sammi so it was changed to Sammi spec so it could be legit. Same cartridge. Same headspace guage. Same brass. Must be a duck. Shep [/QUOTE]
