I have done some homework researching this forum, but can't find a clear answer.
I am debating between 3n37,3n38 and autocomp for my 9mm major load.
3n38 might be too full for the 9mm case, coz I will be using mark 7 autodrive for reloading, i am worrying about the powder spillage.
3n37 vs auto comp, since I see some people in this forum saying WAC produce more gas for the compensator, but felt more snappier.
btw, i am using CK arms thunder open gun. I am using 124gr MG JHP
Thanks in advance.
