The statement states, that the projectile is a lead core, with the copper jacket, thus it would not be hardcast, so that this bullet would expand upon impact.
I'm going to use it in My BFR SINGLE ACTION 45-70 .
AS IT'S NOT A PLUS P LOADING, BUT IT'S STILL A VERY.POWERFUL LOAD FOR THE 45-70 RIFLES, AND HANDGUNS.
BE SAFE, AND SHOOT STRAIGHT.
ENJOY.
