[QUOTE="J E Custom, post: 504517, member: 2736"] You need to know what your chamber length is . SAAMI spec is 2.525 for the AI and 2.540 for the 280 rem. Nosler is the only one loading the 280 AI and recently standardized it by submitting it to SAAMI (It had not been one of the SAAMI cartriges before). It almost looks like they wanted to corner the ammo market for the AI version because they changed the dimensions slightly over the standard AI reamers of the past. they were designed to fire form using the standard 280 Rem cases. Older AI reamers are made long enough to fire form 280 ammo in them. This is the reason you need to find out what is the case length in your chamber. If a fired 280 case will fit in your chamber with out effort it is probably OK, if not you chamber is to short to use without trimming. Ultimately what you want is a case neck that is .010 to .020 shorter than your chamber. J E CUSTOM [/QUOTE]
