[QUOTE="AZShooter, post: 986399, member: 5219"] You never mentioned the reamer's specs. This is going to be a very important one. Here are my notes on the subject from my documents. ________________________________________ 6.5x284 is just a generic reference. 6.5x284 Winchester was the original wildcat. Norma standardized the cartridge with CIP as the 6.5x284 Norma (the european equivalent of SAMMI). All new factory rifles and ammo are likely chambered for the 6.5x284 Norma unless otherwise stated. The Norma has a slightly longer COAL and slightly fatter base. As such, 6.5x284 Norma ammo may not fit in a chamber cut with an old 6.5x284 Winchester reamer. There can also be some confusion when ordering reamers as some will be referred to as "Match" or "Lapua". For the most part, these will usually be 6.5x284 Norma with tight tolerance chambers. If you're ordering a reamer, you would want to get the specifics from the reamer mfg. ------------ Do you intend to use a specific brand of brass? Lapua brass has thicker necks than Norma brass. Do you intend to user a "no turn neck reamer" or neck turn the brass? If it were my custom build I would be ordering the reamer. They only run $140 from Pacific Tool and Gauge. Best to discuss this with Dave and come up with the reamer that fits your needs. [/QUOTE]
