[QUOTE="Good, post: 1825087, member: 18866"] I can’t find that brass. My google-fu must be challenged. 😂 The goal would be to maximize the bolt face. Similar to what Rich has done with the Sherman Short mags. Without digging into the design, It seems like he has extracted as much performance as you can from the .540 face. Why not do the same thing (or similar) with a bigger bolt face For more powder and see where performance winds up? The parameters are just: mag feed keeping it true short action and capable to shoot 300 and 250 grainers without much issue either way. It would be fun to talk to Shawn Carlock and Rich and JE, and guys who have dealt with it, about freebore. Then, when measurements are fairly finalized we can figure powder capacity and performance from there. I’m thinking strict 40* shoulder and as straight sidewalls as practical, but everything is a compromise. Those are my thoughts. [/QUOTE]
