[QUOTE="crashlanding, post: 3031681, member: 44614"] I started last week testing ginex primers in a 7 prc, bullet is a Berger 180 hybrid, 22” barrel, 65.7 grains of rl26. Using federal 215’s, I averaged 2900 fps. With the ginex, same load with no crimp averaged 2934, with an 1/8 turn on a crimp die I averaged 2921 but with a better sd, 38 degree testing temperature, 1 moa group at 100 yards, .020 off the lands. Today I ran a seating depth test with the same load. At .045 off lands went 3/4 group for 4 shots, at .060 off lands went 1/2 moa, temperature was 35 degrees. Still testing [/QUOTE]
