+1......... Didn't feel like messing with variables so I just run one IMR-4895 G.I. Equivalent load to keep things as they were meant to be. Use regular 150 gr. FMJ for paper punching and just substitute some Nosler 150 gr. Accubonds for hunting use. Both bullets shoot well and I feel better knowing my load is M-1 compatible without having to adjust things. Guess I just don't trust my op rod to anything but a standard M-1 load.
