[QUOTE="el matador, post: 1314244, member: 12193"] I assume you're talking about a 338 Lapua here. 2.724" is the maximum case length for commercial ammo given by SAAMI. The minimum chamber dimension is 2.734", so you'd have a small amount of clearance even with a case that's max length. The loading manuals will tell you to trim .010" shorter than the max case length, so for 338 Lapua you'd trim to 2.714". This will give the brass some room to stretch so you're not having to trim after every firing. [/QUOTE]
