[QUOTE="Chester Evans, post: 75101, member: 2956"] Kirby, Chris, Goodgrouper, Thanks for the feedback. I guess my specific questions are - 1. By designing the chamber so the bullets can be seated even with the neck (increasing powder capacity) do you actually gain added velocity with the WSM case (or the 6.5-.284) or is it limited by SAAMI pressure as the article said with standard powder charges. I used the WSM case only as an example since there was a recent article on it. 2. My first hope was to build a 6.5-.284 with a 24”barrel, short action (2.92” OAL) pushing a 142 SMK 3000 fps. I would prefer the 6.5-284 since good brass is readily available. Based on what I am hearing I am dreaming. What should I expect from this combination with a 24” and 26” barrel keeping the OAL at 2.92”? 3. Based on Chris’s idea of a necked down RSAUM, it looks like I could easily get 3000 fps with a 24” barrel. Is this true? 4. My questions on the RSAUM would be - Since no one makes match brass - how good is the Remington brass? Are they going to keep making the RSAUM brass? Obviously I am not an expert in this area, but everyone in this neck of the woods is shooting WSM not RSAUM. Thanks for taking the time to answer these questions. Also – what lead times (approximate) are you guys running to build a rifle these days? 6-8 months or are you out past a year? [/QUOTE]
