I will be shooting this in a hunting rifle made by Alex Wheeler. It’s a Defiance action, Bartlien barrel and min saami chamber. Both RL23 and H4831sc are on the menu with 210 vld. Barrel is 26”. Testing will be 2 shot ladder at 600 with E target for initial testing. Once brass has been fired I will come back and shoot groups.@rhovee can you tell us what type rifle you will be using for this test, hunting type repeater with standard reamer or a single shot type with custom reamer? Powder, primer also? Just curious and thank you very much for sharing
