Just shot some last week in a 24" barrel in the M1 Garand. If you weigh and sort the surplus pulled bullets by weight and tip profile (some are sharp pointed while others are rounder) you'll probably get better groups. In a typical batch of these pull-down bullets they come from a few different lots and weights and shapes vary some. Some say they get good grouping but anything 2" or less would be good. Loading new IMR 4895 powder with RP 9 1/2 primers I get 2700 fps using 47 grains. 47.5 bumps it up about 2725 but that's in a 24" barrel. I would start lower at about 45 grains of 4895 and work up to around 48 grains looking for best accuracy and not velocity. Also in your bolt action rifles you could use a slower powder like IMR 4350 using 150 grain starting data and work up. These 150 FB pulled bullets seem to show near the same velocity and pressure as 150 grain Hornady SP's in my testing but always work up from starting charges.
