what is your method for working up a load and fine tuning it? I know that handgun loads are more simple than rifle, but what advice would you give a relatively new reloader? Here's my situation. I've only reloaded .45acp before. I used 230 gr jacketed bullets with 5.3 grains of Bullseye. That load worked will for me, so I never had a need to change things up. Now, I want to reload 9mm. I've bought some 124gr plated Barry's bullets and I want to use the Bullseye I have on hand. I've asked before about using Bullseye for 9mm and I got recommendations ranging from 3.7 gr to 4.2 gr. I don't have a chrono, so I'm somewhat limited in my ability to gauge performance. What things should I look for as I start increasing the amount of powder? In other words, how do you know when you hit that sweet spot?
Thanks... |

First get your data from published sources. Reloading manual or powder sites, in your case Alliant. http://www.alliantpowder.com/ Begin loading at the start load. (lowest charge listed) Work up watching for pressure signs. (read a reloading manual for more) As long a load functions pistol, shoot groups as you work up. For me best group near max load wins. |

Start at published minimum load.
After dry function test to make sure rounds feed, I make 20 rounds per load. I usually go .2gr steps to max published load depending on the minimum/maximum published spreed. I shoot groups of five rounds from each 20 round ladder through a Chrony but not neccesary if you do not have a chrony. I'm looking for tightest groups that shoot the softest and function 100%. |
