Anything in it, for 147grn 9mm with HP38, or Win231 powder?[/quote]

Hey Leadslinger 231 is terrible powder for 9mm .too fast burning

My Ipsc minor perfect load
was 147 gr sized @.358
using AA No.7 powder with win primers , was dead on 127 power factor.
Low pressure load and extremely accurate (at least in a cz75)
cheers

Actually W231/HP-38 is a perfect 9mm powder. Me and about 14 others use it in PPC, Steel challenge and IPSC. with one guy that been shooting for 40 plus years. It's not that dirty or smoky. I went 1500rds without cleaning and gun still ran like a champ.

I got 4lbs for 160$ to my door in a group buy ( went splits on a 8lb jug ) I run a 124 ( xmetal ) with 3.8 grns of 231 for a mild 1060 FPS load ( 131 PF ) 127 is too close to the 125 PF. Hodgdon doesn't list 147grn loads, because they say using it would be a compressed load. Guys at the club haven't parted with any 147 to test. I've been just too lazy to change my powder measure. Modified a disk on my Lee Auto disk to throw a perfect 3.8. Been running it for the last 6000rds.

Plus when I reload for my 45ACP, I don't need to buy another powder.

My group of ipsc friends had all tried to 231 , we all had same problems , keyholing etc.
This was back in 1989. Maybe they've change the formulation a little bit but we couldn't get a good load without going to a really oversized slugs.
now we were shooting tuned cz75's
they were military grade not commercial market pistols.
maybe that's why. But once we got that a number seven and I have a round wow so easy to shoot an accurate like a laser.

So 1989 ?? Yeah a lot changes in 30 years. But you don't have any idea what you are talking about. How does powder cause key holing? Powder is just to propel the projectile. You get key holing when say a undersized bullet, or say a too soft bullet causes leading and rifling is useless, or a too hard that the rifling doesn't grip, or wrong weight bullet for the rifling. So sounds like the issue was your bullets, NOT the powder. That's like blaming your PCP air, for a pellet not grouping.

Because my group of friends, Most all shoot CZ Platforms from 75/85/Sp01/Shadow 1/2. ALL run Winchester 231 powder, and various types of bullets from 120grn, 124, 125, 135 cast sized to .357, 124, 125 and 147 xmetal, 115, 124, and 147 campros. And I have not once seen a bullet keyhole. With the 1000s of bullets we shot in a night.

I put 5000rds thru my CZ this year with 231, and thousands with other guns, and never key holed 1 round.

Also I brought this up with a older gentleman that used to shoot bulleyes and IPSC in the 80s 90s and when I shot.. He destroyed a 38 super barrel with AA7, it caused throat erosion, it's too hot of a powder. Even the gunsmith agreed.
