30 cal 215 gr. HYB
Finally had an opportunity to shoot some 215 hyb.
factory 700 Sendero SF1 300 RUM, Nosler cases, Retumbo and Fed 215 mag primers. OAL 3.885 .005 off the lands
Started with 88 gr and ended with 92.5 in .5 gr increments. Three shot groups until I narrow down a load. best group so far was 89 measuring .310. From there the groups opened slowly to 1.22 (only two groups) and then at 91 to 92.5 started back down. 92.5 was .72. this group had two rounds in the same hole and one flier. I figured I would start to see pressure signs at this point however everything looks good. 10 groups with only two over 1" seems like a good start. Next weekend I will continue 92.5 to 95 gr unless I see the pressure signs. Then tweak the load and OAL to "hopefully" .5 or better. I do not have a crony so I don't have a clue as to the velocities.
Anyone shoot a factory 26" and know the ball park velocities I may be getting? I was shooting at 3000 feet ele and 80* temp
