[QUOTE="alcesgigas, post: 824880, member: 34925"] Highest average (three shot groups) was 2892. Lowest average (three shot groups) was 2861 with 2843 as the lowest speed recorder; 2925 the highest. I continue to have unusual (for me) experiences with this rifle: With 20* in the base and 20* in the rings I'm sighted in for 100 yards. Cartridge necks are loose; I have to measure each shot at the range. Nosler brass holds up better than Bertram brass. Primers are set to .010 below case head and still once in a while I have to use the priming tool to drive the primer back down so as to fit in the press shell-holder. Last year's dime sized groups are now two inch groups with an occasional one inch group. I worked up loads (above variety) from 88 grains of H-1000 to 91.8 when I encountered tight bolt and lift behavior. Last year the more H-1000 used the slower the bullet and I loaded up to 97.0 with CCI BR-2s in Nosler and RP brass. I'm getting best ES with 91.6 and 3.880 OAL. I've been shooting every other day since mid-June... It's frustrating, but I'll keep looking for solutions and I appreciate all the responses received. [/QUOTE]
