You mentioned CCI small pistol magnum primers, any advantage compared to the regular small pistol primer? I used Bullseye powder, Fed and Win SPP, when I started reloading 9mm. I used about 2 lbs in total before switching to Titegroup, W231 and HP38 powder. They all follow the same load data. We shoot indoors @ 20 m, bullseye shooting and it was like a freight train passing in front of me. Using 125 gr LRN/Coated Bullets, my SP01 Shadowline cycles perfectly @ 3.4 - 3.8 grs. @ 135 gr LRN/Coated Bullets, 3.2 gr to 3.4 gr are just perfect. If you can find 147 grs, I was successful in loading 3.0 - 3.2 grs with very soft recoil. But there is a catch, I do not have a chrono to measure the PF. So if you are shooting IPSC, 3.6 gr is the minimum load for 125 gr bullet to achieve 125 PF (mesaured using a borrowed chrono). But there are also several factors affecting your velocity and PF. Your OAL as crimped will push your pressure as you go shorter OAL. Go with the max OAL that will consistently feed without jams and lowest powder weight suitable to your purpose. Your best advantage using Bullseye is the coarse grain which makes it easy to dispense and measures accurately each drop into the casing. Good luck in your reloading. If you are not sure, ask. Do not guess and follow manufacturers load data to be on the safe side.
