Catalyst008 Posted February 5, 2014 Share Posted February 5, 2014 Ok, just bought a new STI Edge. It shoots great! Since shooting 300 rounds through with normal length 40S&W 1.125" I find that occasionally a round will nose dive lower into the feed ramp and will cause a jam. After searching forums and talking with other STI competition owners, they suggest a longer OAL. I have tested and came up with 1.200 OAL through dry cycling. I then make 50 test rounds using 5.2 grains of Titegroup. and all cycled fine. I think I can drop this a little to 5.0. (The dimple on the primer might be a tad deep) I have not crono the rounds yet. Question; Does anyone have proven recipes for major PF using Titegroup, HS6 or Accurate 2?. I can find plenty for the 180 grain, but not for the 165 grain. Bullets are Montana Gold CMJ Thanks, Quote Link to comment Share on other sites More sharing options...
Zoomy Posted February 6, 2014 Share Posted February 6, 2014 I use 4.8 gr of Titegroup with 180 gr Montana Gold JHP and 1.18" OAL. It gives me 945 gps or 170 power factor. Very consistent and accurate load. Quote Link to comment Share on other sites More sharing options...
Catalyst008 Posted February 6, 2014 Author Share Posted February 6, 2014 Thanks, but do you have any data for 165 grain? Quote Link to comment Share on other sites More sharing options...
Zoomy Posted February 6, 2014 Share Posted February 6, 2014 (edited) Thanks, but do you have any data for 165 grain?Sorry, I seem to have a problem with reading comprehension. Explains my SAT scores.For 165 gr Montana Gold I use 5.1 gr of Titegroup and 1.18 OAL which results in 1040 fps.

Catalyst008 Posted February 6, 2014 Author Share Posted February 6, 2014 Thank you very much. It confirms what I estmated, I have loaded 50 rounds for tonights competition with this recipe, only at 1.200 OAL. We will see how it crono's, weather permitting..... Thanks again Quote Link to comment Share on other sites More sharing options...
Catalyst008 Posted March 11, 2014 Author Share Posted March 11, 2014 Ok, After chrono-graphing the rounds I find that the fps are a lot higher shooting through a sti edge. Just wondering if anyone else as found the bull barrels yield higher pressure and fps? Quote Link to comment Share on other sites More sharing options...
