Today I got out and shot my glock 20. I have the lwd 6.61threaded barrel and a 24lb recoil spring. My Load data goes as follows 180gr Berrys Fmj, with 11.8gr of bluedot powder, CCI 350 Primers, and star line brass. OAL 1.255 chrono results was as follow 1397 as my highest and 1373 as my lowest out of 10shots. Then also did a water jug test and blew through 4jugs will try six next time bullet went to deep in ground to retrieve. Also i used same exact powder and load just switched primers to WLP and got 50-75 fps less i am going to increase the load with the WLP and post the results later this week. Dont feel i have enough play room using the CCI 350 Primers. But i have a little of wiggle room using the WLP. The Recoil is less using the WLP Primers Wanna kill these ads? We can help!
