Hunters Supplies Cast Bullets
Bought a box of 100 to try out my new Winchester .38-55
They are labeled 375 H&H 260 g FP .376
Weight varies from 263.5 to 265.6 a variance of 2.1 grains. That is only .7%.
The diameter is not quite as good.
Although they are labeled as sized to .376, they vary from .376 to .3755
Actual BNH = 16
Lubricated with an unknown moderately hard green lube
They shoot very well and produced no leading.
