First round of trial loads with 572. Just a dozen of each.
Gun is a full size open gun, KKM barrel with two .156 ports, Bedell comp.
1.175 OAL and WSP for all, mixed brass. Bullets are Precision Delta JHP's
My regular load is 8.8 HS6 with a 115 gr, runs 172-173 PF
115 gr, 7.5 gr 572, PF 163
124 gr, 7.0 gr 572, PF 155
I'll focus on the 124's for the next round, probably 7.3, 7.5, 7.7.

Carbide sizing dies use a short ring of carbide which sizes the same size all the way down. So even though the 9mm is
a tapered case, the sizer sizes it straight.
Just measured sizer dies. 38 SC, 38 Special, 9mm U die are all .378-.379.
SO---using a 9mm U die on 38 SC brass MIGHT help a bit. The main difference between the U die and a Dillon
sizer is that the U die has less radius at the mouth of the die--letting it size the case a bit further down.
If the 38 SC cases are expanding a bit just ahead of the rim, is it the result of an aggressive beveling job on the
cylinder? If that's the case, even the U die probably won't help. It sizes further down than regular sizers,
but it doesn't go all the way down.

Finally got my hands on a couple of pounds of 572. I'll get some major 9 test loads ready tomorrow and chrono them Saturday.
So far---it's not as dense as HS6. A full 9mm case of 572 ran 10.8-11 gr. HS6 is around 12.5.
I think I'll start around 7.0 with a 124 at 1.180 and see what I get. REALLY hoping it acts like the old HS7. I've heard the
burn rate is slower than HS7----

I've had 2 pop o my Dillon 550B--out of at least 100,000. LOUD!!!!
Haven't done it myself--but have seen the aftermath of it happening to someone else,
having the whole primer tube full go on a Dillon.

Since this is still trollin' along------
We should probably get rid of "Lady". Change it to "Female".
Lady (as does Gentlemen) implies a certain level of decorum. I'll not
name names (wouldn't be gentlemanly), but I've shot with or witnessed a few who were
obviously female---but could cuss and throw an impressive fit when a no-shoot would jump
in front of a bullet or the spin of the earth would rotate a long range target out of the bullets path.
.
Hardly Ladylike!
Way to throw Nancy under the bus.
Dang-----Probably should have thought that one through a bit.

Atlanta Arms did a short 9mm Major a few years ago. It wasn't a 115----it was a 124 JHP. The headstamp was 355 Super.
Good stuff. I've still got maybe 150 rds of it, I fire a few in a new gun sort of as a "control". The stuff was VERY
consistent, running right at 172 PF. It used a powder that I'm not sure was ever positively identified.
They stopped making it. Liability, demand, the dearth of components that hit a few years ago---I've never really heard why.
Personally there is only one person I fully trust to stuff darned near 9 gr of HS6 under a 115. Me.

If you have small hands/short thumbs they work well. You can hit the release without breaking grip and flipping
the gun. If your hands are big enough to hit the standard mag release, there is no advantage to the right side
release.

Just a hunch but maybe the slide is hitting the comp when the gun returns to battery.
How much clearance do you want between the comp and slide, and then is there a point of to much clearance between them.
Haven't had any issues with .005" to .007" with Bedell Titanium comps. More doesn't really cause any problems,
the gap just becomes more noticeable.

Had a Limited HC. 200 gr Bayou RN, 1.200 OAL. Ran K10 mags.
ETA----just noticed the dates. A 4 month old thread back from the dead!

Get some coated 147's. I use Bayou, but any of the Hi-Tek coated ones are fine.
Start around 3.2 gr N320, with a OAL of 1.145. Work up to your desired factor.
I load 3.4 N320, WSP, 147 Bayou, OAL 1.145. It makes between 129 and 136 PF in:
3 Glock 17
1 5" M&P
2 CZ 75 SP-01
1 Colt 9mm Govt
1 5" Springfield 1911

Looking forward to giving it a try as soon as I can find some locally. Hoping it's closer to the old 571/HS7---and I've seen
a few references on other sites stating it may be a bit slower than HS7. That gets it into 3N38/N105 country, with a denser
powder.

I don't care one way or the other for local matches and practice ammo. As long as
it's not split, the primers don't fall out and it fits a case gauge---it's good to go.
Usually purchase a few thousand nickel 9mm for major match ammo. I do believe
it's just a touch slicker, there is a better chance it's actually once fired, and the rims and
extractor grooves are generally not beat up. It seems to feed and extract just a touch smoother.
Load it , shoot it at Sectional/Area matches, walk away.

The target itself is legal---I kind of like it. Hmmmm---- setup is tomorrow for Saturdays match----
The only thing that would make it illegal is if they tried some sort of mozambique drill instruction in the WSB.
-
I keep telling myself it's cheaper than golf---------definitely cheaper than anything that has a motor and the word "racing" involved.

HS6 is wonderful in 9mm. I need to try CFE at some point in time.
I can't tell the difference between CFE and Autocomp. Agreed HS6 works great---wish they still made HS7

Gen 2,3,4 G17's
2 CZ 75 SP01's
1 M&P
2 1911 9mm's
3.4 N320, Bayou 147, 1.145 OAL. WSP, mixed brass.
Runs 100% in all, PF 129-134 depending on which gun.

Smoked heavily for 20+ years. Quit a thousand times---but not for long. Tried patches, gum,
meditation, cold turkey. Nothing worked. Eventually got around to trying Zyban (bupropion).
That was May of 1999---haven't smoked since. YMMV.

+1 for the Boss hanger. I've also got a Springer hanger that i haven't tried yet, but it looks like it will do the same job as the Boss
in a smaller package.
-
If you make some--make an extra. I'll take it! Heck--if you decide you don't like the one
you just got, let me know. Been looking for one to try for a while.
Sounds like a good idea. Might get in the way of a left side slide racker, and long
thumbed folks might have some issues. Looking at my gun with a Cheely setback
and visualizing the area above the thumb safety with the sight at 45°, things
get a bit tight.

Was loading 1.200 for a Tanfo Limited HC using K10 mags with Grams guts. Ran 100%.
-
Was loading 4.5 N320, Bayou coated 200 RN, 1.200 OAL.
It ran right at 172 out of a Tanfo Limited HC, and was pushing 180 out of a SV Sight-tracker with a AET barrel.

Go with the torx drive rather than the hex----much less likely to slip. Standard is 3/8, you probably want 1/2"?
From the Shooters Connection site:
Item #: Torx Screw Set- 1/2" -
I like the Bladetech on a BOSS hanger---I prefer just a touch of muzzle forward holster angle. My wife likes the Ready Tactical DOH.
New 9mm Major powder? Win 572!
in 9mm/38 Caliber

Not bad. Only fired 12 (4 sets of 3), but the dot tracked well and it didn't feel quite as snappy as CFE or Autocomp.
Probably try 7.8 with the 115's next time around.
