Do I hear a second to the motion to accept the WOODLEIGH BULLETS LOADING MANUAL, 2014 edition, as the BENCHMARK benchmark for .458 Winchester Magnum, with bullets from 400 grains to 550 grains ?
Reference to that data will be used for comparison of any rifle shooting same BENCHMARK load without regard to ambient temperature. By extension, other bullet makes of same weight may be considered for effects on MV. Ditto for effects of differing seating depths. Ditto the effects of shorter and longer barrels. It is a place to hang the thinking caps of the Knights of the Square Table.
Ron aka "Rip" for Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary .458 Winchester Magnum, Magnanimous in Victory THE WALKING DEAD does so remind me of Democrap voters. Donkeypox.
