The net is full of load data. Just make sure you look at more than one place for the same load. One may have max at 5.5 grains and other says 5.0. Never start at max. I like to split the high and low and start from there. There are a bunch of hand loaders around here, you can always start with us too. I keep notes of what worked, what didn't and what was hotter than donut grease and to not go near lol When I'm testing a bullet/powder/primer, I always load for my FN509 with comp. I want the comp to run. I like to stay around 1200 FPS for 115 grain loads. It runs the comp reliability and if it runs this gun, it will run in anything. 124 grain and 147 grain stuff, I try and load to the same FPS as my carry ammo. I prefer to get the same snap/bang/report/recoil as what I carry. You can start with a load in the middle, load 10 rounds, work up in .3 grain increments loading another 10 rounds. Now, I load and shoot off a chrono for everything. It's not needed, but it tells me what my load is doing and shows me how consistent my stuff is. Make yourself a 5 to 10 of each test load and run them. To put it bluntly, if it's a safe load and cycles the gun, run it. You really cant go wrong there. I load for accuracy and consistency. I put my 9mm brass through the same loading process as my 6.5 match stuff. Check out Sears shooting sports range in El Reno. It's usually light enough people wise that you can take your time testing loads. Last bit of info I feel is the most important. Take notes and log everything. You have no idear how many times I have gone back to notes 10 years old and answered my own questions.
