I expect to continue tinkering with OAL and primer choice, while looking to improve accuracy. However, even if this load proves to be the best possible combination (seems unlikely), I already will have a load that is a step above my former top choice, the 40-grain Nosler BT launched at 4400 fps from a Savage 22-250 (BenchMark again!).

Comparative Ballistics: Selected Best Loads 5mm/35 SMc & 22-250 Rem.
