Fine-Tuning My 9mm Handloads

[RangeHot]

I've been experimenting with different powders for my 9mm loads using 115gr FMJ bullets. So far, I've settled on Unique and am getting some decent groups. How do you guys determine the best load data? Feel free to share your own insights!

Nice, 115gr FMJs are fun to play with. I usually start slow, stick to the manuals, and watch for pressure signs...the primer flattening, case stretch, that kinda thing. Then I tweak for accuracy, chrono for consistency, I keep a log of every round, it saves headaches and helps dial in the sweet spot

I've reloaded for 46 years. Never had a chronograph, nor used one. I adjust loads (of everything) for accuracy, consistency and comfort in shooting. I NEVER carry reloads in a CCW or EDC firearm. Those are always factory loads. Since I only use reloads to punch holes in paper, it makes little difference whether they are a poof, or a kaboom. Some reloading manuals have a recommended accuracy load, like .45 ACP. If they do, that's what I load.

I start with published load data and work up slowly, watching for pressure signs and checking accuracy. Using a chronograph helps fine-tune velocity
