kujo929 Posted November 28, 2019 Share Posted November 28, 2019 What powder/bullet combos have you found to run reliably long term without major gun breaking? (cracked slide,frame, comps, etc) What kind of round count? I’m curious if some bullet and powder combinations are better or if pressure is similar. Or if someone knows of pressure tests that have been done, but I haven’t been able to locate that. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
FTP_Shooting_Sports Posted November 28, 2019 Share Posted November 28, 2019 You can actually make major under SAAMI specs using 3N38 and 147 projectile so I would say it's one of the better powders for pressure. You will also see some gun manufacturers that make open guns will only warranty their guns if you use this powder. Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted November 28, 2019 Share Posted November 28, 2019 (edited) There was a posting here few months ago that indicated he thought most cracked slides were because of improper lightening of the slides … If you can find that post, you'll be well ahead in your search for the perfect powder. But, as FTP mentioned, 3n38 is probably a good bet for powder. Another way to look at it, is that 100,000 rounds will cost you c. $12,000+ for the ammunition. By the time you've spent $12,000+ for ammo, you might not mind too much spending $1,000 to update your blaster.

Well said Jack I've shot every "popular" powder there is and honestly can't shoot the difference on a timer, but that another story! My oldest gun is well over 100k with WAC and has an 11 oz slide. Gun is loose now but still shoots a 2" group at 25 yds. As said above if the gun is built right, pick a powder, load to 170+ and go and shoot it Link to comment Share on other sites More sharing options...
zzt Posted November 29, 2019 Share Posted November 29, 2019 The only problem with 9mm major is case capacity. Generally speaking, you can get the gun to run soft, or flat, but not both without some compromise. 3N38 is a nice powder, but not for 9mm major unless you want to shoot 124s or 127s. You cannot get enough of it to stay in the case for 115s. So I'm using mine up for minor steel loads. My go to powder for major is Shooters World Major Pistol powder. It is denser than 3N38 and doesn't spill all over the shell plate when indexing. It is also very compressible; something that cannot be said of 3N38. My load is once fired, fully processed brass, CCI500, 10.2gr MP and 115 HAP at 1.161" OAL. Super clean, accurate and an SD of 4.9. My slide is 10.5 oz., but has full metal everywhere that counts. I run an 8 lb. recoil spring and have no doubt the slide will last longer than I will. Link to comment Share on other sites More sharing options...

Full, but not so much that a lot spills out when the shell plate indexes. With a 115 loaded to 1.161" OAL, the powder is not compressed. I copied this picture from an article in Shooting Times. It is a little more full than the AA7 case in my roll sized brass. Link to comment Share on other sites More sharing options...
Posvar Posted December 8, 2019 Share Posted December 8, 2019 Thank you. I use 7.0g of N340 and it’s abour as full as the A7. I’ll grab a pound of major and try it out. Link to comment Share on other sites More sharing options...
