Chapo Posted January 28, 2020 Share Posted January 28, 2020 So I just came back from the range after shooting a progression of HS6 from 7.4 to 8.3grs. I have a G34 w a carver 4 port comp and an 11lb spring. Also have reduced power plunger spring and striker spring. I recorded the session with my phone, but after viewing all the shots in my phone, I couldn't tell powder amount shot was the flatest. Has this happen to you? I'm inclined to go back to the bench and make more bullets from 6.5 to 7.3grs to see if the gun will cycle and determine if the recoil is less. Any suggestions??

Hi-Power Jack Posted January 28, 2020 Share Posted January 28, 2020 Go for it. Don't forget, there's a difference between flat and gentle. More powder might buy you less muzzle climb but more of a hit to the hand. Your timer is your best friend here. Link to comment Share on other sites More sharing options...
Absocold Posted February 3, 2020 Share Posted February 3, 2020 If you can't tell the difference from shooting or from video, use the lowest charge that meets specs and runs reliably. Or as Jack said, let your timer be the judge. Pro tip: If you're doing load workups in the powder amounts you listed, you really should be firing them over a chrono and checking closely for high pressure signs. You didn't list your bullet weight or seating depth, but 8.3 grains of HS6 in 9mm, even under a 115 grain bullet, is getting close to big boy territory.

That right there is NO JOKE! I had 8.2 grain loads using 115gr bullets just about destroy my Sig P938! Link to comment Share on other sites More sharing options...
chgofirefighter Posted February 12, 2020 Share Posted February 12, 2020 FYI, ditch the G34 open gun and get yourself a 2011 open gun... Once you go 2011 you'll never go back! CK Arms 2011 9mm open I loaded to 7.8 of HS6, worked perfectly... Link to comment Share on other sites More sharing options...
