New to the gas check thing. Looking for recommendations for appropriate check material thickness for the mold I just purchased from JTknives. Searched the gas check forum and only found general advise for different calibers.
JTknives mold specs .227 drive bands with a .214 check shank, so a .013 difference. Divide by 2 and nominal material thickness comes to .0065. I plan to size no smaller than .225, a thou or two bigger if the gun requires. How much extra thickness is required to assure a good crimp? I will be crimping with a Lee sizing die.
Any vendors/members selling checks appropriate for boolits from this mold?
Thanks in advance for any advise.
