Hi there,
i have just started reloading my 9mm brass on my brand spankers Dillon 550B.
I have done about 400 rounds through, and have tested them to see if they chamber and extract properly in my P226 Sig, with no problems.
I notice that when the brass gets resized and deprimed, that the die only resizes it from the projectile end to about 2-3mm away from the rim at the base of the casing. this leaves a small bump in the case. Once the round is finished, it looks fine however still tapers in a bit from the primer end.
Is there a way to stop this happening and to make the die resize the entire length of the casing? I have tried to adjust the die but the depriming pin is already touching the baseplate.
Also, can someone please confirm what the OAL of a 9mm bullet is?
thanks,
Strabo.
