[QUOTE="ta406, post: 945008, member: 34644"] I have been having a hard time finding a good load for my 338 Edge. Last weekend I loaded up 12 rounds of 90 grains of H1000, CCI 250's with both Norma and R-P brass. All groups fired at 200 yards 3 rounds of once fired R-P brass, 300g SMK on the lands - 1.10" group 3 rounds of once fired Norma brass,300 SMK .005 off the lands - 1.80" group 3 rounds of once fired Norma brass, 300 Berger OTM .005 off lands - 2.3" group 3 rounds of 8 fired R-P brass with loose primer pockets (I forgot to measure the neck tension but just the weight of the handle on my Rockchucker was almost enough weight to seat the bullets) 300g OTM on the lands - .650" group Weird thing is that the last group with brass that probably should have been thrown in the trash was .650". I'm going to retest this load with Norma and R-P brass but I was wondering if any of you have experienced a rifle that was extremely sensitive to seating depth? Would .005 difference in seating depth make that big of a difference? Thanks in advance [/QUOTE]
