I have finished breaking in my barrel and have tried a few different loads using Benchmark and H4198. Using a Harrel powder measurer starting getting pressure signs at 49 with benchmark and 42 with H4198. Both would group about 1/2 inch just under these points.

Made some adjustments to brass turned neck a little more and used larger neck bushing. Tried to get different primers none available. Went to range worked my way up to 46 with H4198 primers flowing into primer hole. 51 with benchmark both a little over 4100 fps with 33 v-max.

Tried some different primers CCI BR4 stopped the primers from flowing into primer hole. Worked load up to over 4350fps with 52.5 of Benchmark on the Harrel. Was getting very good accuracy close to 4300fps.
