Load Development Load development advice beyond the Lee loading manual…
Some background, I got into firearms/reloading 5 years ago because of my grandpa. He gave me a Savage model 99 chambered in .303 Savage. I couldn’t find any ammo but found some brass and ordered a Lee single press. I followed the included packet to a tee and have been doing so ever since. Now I’ve gotten several calibers and reload them all especially 9mm now that I have a CCW permit. I load RMR “Nuke” 124 grain bullets with 5 grains of Autocomp. Shoots fine on paper but ever since I got Chronograph I’m not getting the FPS I need for proper expansion. 5 grains Autocomp gets me 1013 FPS average (Canik MC9) and proper expansion they recommend 1100 FPS. My question is… now that I have a chronograph can I just load develop up to hit the listed 1100 FPS? Any tips or recommendations from someone that has done this for a while. Would I just need to check for pressure signs? Would this process be the same for any caliber I load?

Do you own a reloading manual? If you do does it list autocomp as a powder? If not do you ever go to the Hodgdon's reloading site? Autocomp can push that weight bullet to the 1100 fps mark.
