Your powder selection for revolver? 9mm


Recommended Posts

929 S&W revolver. I had a small amount of Clays powder I wanted to use up BUT I had another revolver shooter tell me as far as case expansion, Clays was to fast??... Which maybe true, as I had some moon clipped cases that didn't extract easily recently and this was when using Clays.... My load is 2.8 grains of Clays , Acme 145gr. red coated bullet, 1.10 OAL( same load  used for PCC carbine) cronos consistant 129 power factor. Dillon 650 /Lees "U" die, Shockbottle gaged, Fed nickel brass. I have 3n37, 1# of 231, lots of CFE pistol,and Auto Comp, Fed 100 primers. Since the PCC uses Glock styie mags , I didn't want to change the OAL for revolver (I know they could be a bit longer for the revo..). Anyone have the same results with Clays?.

I don't load 9mm for revolver but in my Glock/1911's Clays/ClayDot filled the case and reached a point where velocity ceased to rise with increases of powder.  That is usually a sign that you've reached the end of its range, and pressures usually start rising exponentially rather than in a linear fashion.  The problem was I was just below of my target velocity.

I also loaded the same bullet with ClayDot (the newer Clays and ClayDot in my guns run virtually the same velocities), same charge, at 1.115 OAL and also achieved a 129 pf, with no issues.  But accuracy wasn't as good as the 3.0 Titegroup load.

The other issue is getting Clays/ClayDot to meter from a Dillon type measure below 2.8 grains, Dillon actually makes a special "Small Charge" Powder Bar to address that issue.

So for my 9mm 1911/Glock's I settled on Titegroup.

I load 160 gr. bullets for my 929.  I mostly use N320 but since I use a lot of WST in other loads I tried it also for the 929 and it worked well.  Both of these powders are very clean in the 929 loads which is important for me.

I had same problem years ago, I use wst now and am happy.

Be aware that WST is Inverse Temperature Sensitive,  it will lose velocity as the temps heat up.  I noticed it in 45 acp years ago and a buddy went to no score in an ICORE Regional due to it in his Revolver, I think it was 38 Special.

I am using TG under 165 plated and 147 jacketed.

 

Accuracy with Clays in 9mm has always been garbage.

 

Would you post some load data for Titegroup, please?

I am aware and have had no issues at majors, lowest chrono I've had was 129. Thanks

Sport pistol and both SNS & Bayou have worked well in my 929. Have shot 0.358" 160's more than anything but have seen good results with 125's.

 

A thing about my 929, change bullet and you need to adjust sights, fussiest gun about point of aim versus bullet that I have ever had.

How much?

I use 4.0 grains with a 125 grain LRN. I use a Lee bullet mold and I powder coat them. I use these for steel challenge.

3.1 grains of N320, 150 Blue Bullets (listed at 147, but .356 diameter, so they are 149-150), 1.120 OAL, Federal #100 (or GM), Federal brass.

 

The two components that are revolver-specific are the brass (bought it new and only use it for revolver) and primers (I save Federals for revolver, mostly use WSP for all other loads). I prefer to keep the powder dispenser and bullet seating dies calibrated and not tinker with them, so my shorter OAL allows me to load 9mm for my CZ-s with shorter chambers by simply using mixed brass and WSP. I will have to change things a bit when I start loading different bullets, which I have to to do because Blues are fouling my PCC comp pretty bad and accuracy is crap (6" at 25 yards, so clearly there is at least quite a bit of contact with the compensator).
