Ran some loads of 33 gr. and 34 gr. Rel-7 through the .375 Win last night...very poor results with these charge weights.
I rolled up some loads of 36 gr. and 36.5 gr. Rel-7 also and hope to be able to try them out today sometime. I've read the 36 gr. load with a 220 gr. Hornady FP is a very accurate load for alot of folks, so I'm looking foward to seeing the results. So far the 35.5 gr. load has been my most accurate, putting 5 shots inside 1 3/8" at 100 yards.
