unisonicz Posted June 17, 2020 Share Posted June 17, 2020 I have been a lurker here for a bit have done a bit of research and worked up a 38sc load for my CK Arms Thunder open gun. 3 popple and 2 port cheely ti comp. I just purchased the gun from a guy at my local range. It is a blast compared to my glock 19.5 carry optic I have been shooting in USPSA matches. I got 11 pounds of sr7625 with the gun. Current load is 7.1gn 7625, cci#500 primer, 125gn Rushmore coated .355 and 1.225 oal. Getting between 168 and 170pf. What would be a decent powder to get next that would work well with my setup since sr7625 is no longer produced? Thanks (Reloading using a lee pro 1000 and lee carbide die set.)

nhyrum Posted June 17, 2020 Share Posted June 17, 2020 Hs6, autocomp and vihtavouri 3n37 will probably all be good Sent from my SM-G975U using Tapatalk Link to comment Share on other sites More sharing options...
36873687 Posted June 17, 2020 Share Posted June 17, 2020 Aa7 is awesome powder Link to comment Share on other sites More sharing options...
kneelingatlas Posted June 17, 2020 Share Posted June 17, 2020 Please don't go to all the trouble/expense of picking up 38sc brass just to load something you could shoot out of a 9mm case. 38 has more case capacity, so use it! N105, Shooters World Major Pistol, AA9, use 11+gr of powder and get that comp working Link to comment Share on other sites More sharing options...
AverageJoeShooting Posted June 17, 2020 Share Posted June 17, 2020 I tried a bunch of powders and for me AA7 has been the best and most reliable. You can always find it, its affordable, it meters perfectly, and i get a full burn with my primers. I think its actually the best 38 sc powder.

sauza45 Posted June 17, 2020 Share Posted June 17, 2020 N105 or 3n38 are good. I use N105 Link to comment Share on other sites More sharing options...
zzt Posted June 17, 2020 Share Posted June 17, 2020 I agree with ka. You have gobs of case capacity, so make a lot of gas. VV 3N38 is a loved 38SC powder and is the fastest I'd consider. SWMP, AA7 and N105 would be next slowest. You can go slower yet, but be aware there is such a thing as too much gas. When excess gas starts jetting out the front of your comp, it increases recoil. Personally I'd skip the 3N38 because of its speed and expense. I'd start with AA7 and ladder up to 175PF. If you fire at a white no shoot from 2" away and have little or no splatter around the bullet hole, try a slower powder and make another ladder. When you start to see much splatter and residue on the board, back off a tad and call it done. Link to comment Share on other sites More sharing options...
unisonicz Posted June 18, 2020 Author Share Posted June 18, 2020 (edited) Great info, appreciate it! I will probably switch to aa7 once i get through all of this sr7625 I got with the gun. From my bit of research it is a medium to faster burn rate. I may try bumping it up to 175pf to see if i can get it to work the comp a bit more. Thanks!

After you try it you'll order 8 lbs. of AA7 and use the rest of your 7625 for minor. Link to comment Share on other sites More sharing options...
