Are they longer than a factory 115 grain FMJ? What is the listed shortest depth you can seat them at? Since feeding in a semi auto is not a concern i would seat them shorter at the starting load then work up. Wirh 9mm just a taper crimp to remove the flare is all that is needed. Do not worry about the crimp groove.
