[QUOTE="Alan Warner, post: 1329086, member: 100752"] Oscar: The design concept is Jons'. I asked him if it would be OK to transpose it to the 375 and he was most obliging. Made up some estimates of water capacity to increase volume over what the Barrett holds and went to town with tooling. Having had experience from making the tooling for the 14.9 and ending with the rev4 version,(my changes) I hit it on the nose with the 375. Tossed the capacity issue around with Josh and Dan for about a week prior to starting. Water of the Barrett is 215, the 375 Warner is 236. I've yet to hear from a couple of customers about the Barrett's velocity performance. I'm working on a customer project that is based on the 50 with an expanded shoulder diameter and 30 degree for a 375 that shows a water cap of 263g. Tooling is done and only a few will be made till we ( the guys heading up the assembly) determine if it needs to be shortened a tad or two. They are just now chambering and readying for pressure tracing. We have taken a few orders for the 375 Warner and will are producing dies and brass. The reamer is still proprietary so chambering for now is only available here. That may change at some point. The primary reason I wanted to use a 50 is ignition. I am convinced that the Chey Tac does not have enough primer fire to light it off well. I get SD's in the single digits and ES mostly less than 10-12 with the 375 Warner. And that is with a powder that is not ideal . Alan [/QUOTE]
