Thanks in advance for any responses. I just started loading for a new 454 Casull, ordered a supply of bullets from two sources, 360. 345, 300 and 280 grn hard cast with gas checks. I also have some Hornady XTP Mag 240 grn JHPs.
The 360 grn bullets, from samples I've tested. weigh from around 334 grns to maybe 360 tops with most 2-4 grains on either side of 350. These are from company "A". Company "B" supplied the other weight bullets and from what I've sampled, they are within 1-2 grains of the advertised weight.
The 360s are measuring .975" versus the 345s@ .855.
What would you do regarding the 360s? Should I weigh each one and sort them out?
I've never loaded cast before and was surprised to see the variation with the heavier weight bullet as they look well cast and consistent. I imagine that accuracy would be affected shooting the same load with bullet weights ranging from 334 +/- to maybe 360. Obviously, I won't use a powder charge for 340 grain and, without checking, load a 360!
