[QUOTE="mooredj, post: 3065603, member: 121913"] This is the modeled load data using GRT. I need to provide an explanation on why I show the freebore as 0.236. It is actually the traditional freebore as everyone knows it plus the chamber to bore transition distance added in. That distance is 0.0182 so that plus the traditional freebore of 0.218 equals 0.236. The load is slightly under compression but I believe GRT is slightly conservative based on actual data so I am hoping to use just a little less powder to get to 2900fps. Anything extra is a bonus. The 7 SAUM is a very efficient cartridge at 32.4% set up with H1000. [ATTACH type="full" alt="1710988876690.png"]555909[/ATTACH] [/QUOTE]
