So I am planning on loading 45/70 in the near future, and am going to put a GC on it. From my understanding, the gas check's job is to simulate that of a copper jacket and allow the use of cast at higher pressure loads.
Would the alloy used need to be very hard if a GC was used? Obviously hardening the bullet to what it would be without a gas check isn't required, as that would defeat the purpose of the check, but logic would dictate (mine atleast, and it has proven to be lacking on more than one occasion ), that the sides of the bullet would shear off from the stress of the rifling. Any thoughts? Anybody worked with the hardness in a checked bullet at high vel. rifle loads?
For that matter, if the check is doing a good job of keeping the bullet from leading in higher velocity loads, couldn't I just check pure lead bullets for use in my 9mm loads rather than alloy my lead up to the proper hardness (at a cost to me of about $10 per 500 rounds of 124 gr). Any help is greatly appreciated as always!
