It is almost right up to the top and a pain to load. I also forgot to mention thst i can only load to 1.245" with n105 because it won't compress much beyond that. 3n38 is much easier for me to load without spilling.

I don’t have any popple holes in my gun, so should I dial down the powder somewhat? Link to comment Share on other sites More sharing options...

You actually may need somewhere around 10.7 to guarantee major. The benefit to using so much powder is thr gas created. Higher charge weight = more gas to work the comp.

abigger04 Posted December 23, 2017 Author Share Posted December 23, 2017 I'll have to look for that powder to try. I'm almost out of CFE. Link to comment Share on other sites More sharing options...
abigger04 Posted February 4, 2018 Author Share Posted February 4, 2018 Just thought I'd update this thread. I finally had a chance to chrono several loads I've been working with: Full length STI 38 sc, T2 comp, no popple holes. Results are based on an average of 5 shot strings. CFE 7.1 gr 125 HAP JHP 1479 FPS OAL 1.235 PF = 184.88 (Too hot!!) CFE 8.1 gr 115 Hornady XTP 1418 FPS OAL 1.235" PF = 163.07 (Too cold!!) AC 7.3 gr 124 MG JHP 1377 FPS OAL 1.235 PF = 171 (Just right!) AA7 10.0 gr 115 Hornady XTP OAL 1.235 1381 FPS PF = 158.81 IMR 4756 7.5 gr 124 PD JHP OAL 1.235 1295 FPS PF = 160.58 Link to comment Share on other sites More sharing options...
tomjerry1 Posted February 4, 2018 Share Posted February 4, 2018 I have settled on 10.2 gr of AA#7, HAP 125, gets me right at 174 pf and it does produce enough gas to work the compensator. Super Comp and no popples. I don't find that AA#7 is extremely dirty, not as clean as VV tho. Link to comment Share on other sites More sharing options...
