ramairthree Posted November 11, 2015 Author Share Posted November 11, 2015 3.8 grains Bullseye 1.125 OAL WSP 743 FPS PF 134 This has been my typical problem with 40 minor. Using Autodiscs to load, And end up just below minor, Then the next load overshoots by a good bit and enough that I loose the perceived recoil advantage over 9mm. Bullseye has worked out better than WAP and WST, but still not what I wanted. Link to comment Share on other sites More sharing options...
dave33 Posted November 11, 2015 Share Posted November 11, 2015 Dump the disks and get the new Lee Auto Drum. Dial in what ever charge you want to the exact tenth of a grain. Huge improvement over the disks and pretty cheap, around $35 online. Link to comment Share on other sites More sharing options...

Huge improvement over the disks and pretty cheap, around $35 online. Thanks, got one coming. Did not even know about them. Have been using auto disk and auto disk pro since the 90s. Never much luck with the micro bar adjuster. At times have drilled out a disc hole to get an intermediate size. Will see if any luck. For me, 40 always has some spikes in FPS in various powders. Just not linear for me like 45 or even 10mm. Link to comment Share on other sites More sharing options...
