Well, I loaded up some 115 gr. Gold Dots and 115 gr. XTP HPs. The G.D.s functioned absolutely as posted data listed @ 1200 fps. consistently with 5.9 grs. Longshot COAL of 1.125". The XTPs as well were charged with 5.9grs. of Longshot but were seated to 1.095" and delivered 1050 fps. very consistently. So I'm now trying decide which way to go with the XTPs to get the velocity up around the 1200 fps mark. If I seat a little bit deeper, say 1.070" will it likely improve velocity? Or should I try increasing the powder charge one tenth a grain first? As you can tell I'm not very 9mm experienced with modern powders and bullets. I stopped loading for the 9mm back in the 1980s when G.Ds, XTPs, and Longshot were yet to have been developed.
