probably correct.. the only guns that need the rim probably shouldnt be shooting 38 super level loads anyways. and stick with 38 Auto...
According to chart I looked at it seems Everyone but Remington has done just that and all 38 super ammo is now near rimless.
That's not quite accurate. The only traditional semi-rimmed 38 Super case in that table is the Remington. Other brands make semi-rimmed cases, but are not listed there. All the others in the table are specifically noted as rimless super comp and clones. It's from the article I posted the link to, which describes the known rimless Super Comp and TJ cases made at the time. Other semi-rimmed brands are not in the table because the article focuses on the rimless variants. Most of those same brands also make semi-rimmed 38 cases. Right? Starline has two semi-rimmed 38 Super cases in addition to their Super Comp and TJ lines.

u will gain pf with .356 at current charge.
Why?

I broke a firing pin on a S&W 686 with a hammer mounted firing pin while dry firing. It does happen.

Published load data with pressure testing will tell you if your load exceeds standard pressure - or not. Consult loading manuals for that information.

OK just found a bunch of wadcutters that are hollow base sweded lead that I will load up and test. Thanks to everyone for the replies. Craig
Which ones?

The lube is most likely the source of the smoke. If you like wadcutters (or any lead bullets) but don't like the smoke, switch to Hi-Tek coated bullets.

You'll have to slug it to know. Never assume. Always measure.
9mm, 38 Super, and 38/357 all have the same SAAMI barrel specs. .355 groove diameter +.004. Anything within that range is in spec.

In case anyone is interested, the article below discusses this topic and provides evidence showing that a heavier bullet has less recoil than lighter ones when loaded to the same power factor with the same powder.

I've found A#7 to work fine in 9mm minor ammo. I don't have much experience with it and 115 grain bullets, but it produces very nice groups with 124/5 grain bullets from a 5.0 inch Kart barrel. For example, 6.0 grains and a 125 HAP at 1082 fps from the 5.0 inch barrel. 10 shots in 1.53 inches at 25 yards. And the velocity extreme spread was low at 27 fps. It's definitely worth trying.

Funny thing about this 617, sometime, I don't know when, the barrel got bulged !!
You can feel less resistance when you slide a bore brush down the barrel, it's about 2-2.5 inches from the muzzle (6" brl).
Did it get bulged, or maybe the wide region was made during the rifling process? If the barrel is bulged, I would expect there should be a bulge on the outside dimension of the barrel as well, which might be detectable with calipers? Maybe?

The Eley rounds I had some years ago measured 1.253" OAL +/- .001". The SAAMI max OAL for 38 Super is 1.280". You'll have to measure yours to see if they fit within those specs.
That said, some mags can be a little short front-to-back. The way to test them is to use ammo with a known, measured OAL and see what fits and travels up/down through the mag without rubbing.

Some of the common ones are in this article:

Wouldn't have believed it but here you go. https://www.steinelammo.com/product/357-magnum-125gr-spire-point-rnfp-copy/
Those bullets have been around forever. They are in my old Lyman loading manual, circa 1970s.
Matts Bullets sells them.

It's not unusual to see barrels of the same length produce different speeds, and for shorter barrels to be faster than longer barrels.

N105 or Accurate #7 will work, at, or just a little above, published load data, depending on your barrel.
https://www.shootingtimes.com/editorial/super-powders-for-the-38-super/99160
Recoil force will be just a little more than a 45 Auto with a 230 grain bullet at 850 fps, so maybe like a 45 +P.
125 @ 1500 fps and 10 gr of powder = 5.60 ft pounds in a 2.5 lb gun.
230 @ 850 fps and 7 gr of powder = 5.30 ft pounds in a 2.5 lb gun.

Guys:
With the threads on the 929 I wonder why they are in demand.
Seems to me that they are a Model 27 given their .38 cal bore diameter, but limited to one cartridge.
GG
The 9mm and 38/357 have the exact same bore and groove diameter SAAMI specs, which are 0.346" bore and 0.355" groove +.004". Anything with a groove diameter between 0.355" and 0.359" is within spec for either caliber. Therefore, there is no such thing as a 9mm bore/groove diameter and a separate and different 38/357 bore/groove diameter. They are the same, like it or not.
The only difference between 9mm barrels and 38/357 barrels is their rate of twist.
9mm = 1:10".
38/357 = 1/18.75".
But twist rate is optional.
I've slugged many 9mm and 38/357 barrels and their groove diameters cover the same range, except some Colt revolver barrels that were under 0.355". Colt has a reputation for that, at least the old barrels. I don't know about the new ones.
The SAAMI bullet specs are different.
9mm - 0.3555-.003
38/357 = jacketed 0.358-.003. Lead 0.359-.003
SAAMI specs: https://saami.org/wp-content/uploads/2019/02/ANSI-SAAMI-Z299.3-CFP-and-R-Approved-2015-12-14-Posting-Copy.pdf
The SAAMI bullet specs are different.
9mm - 0.3555-.003
38/357 = jacketed 0.358-.003. Lead 0.359-.003
Which is why we see 9mm jacketed bullets at 0.355" and revolver jacketed bullets at 0.357".

Remember that 9MM is a tapered case and that .356 is designed for 38 Super, not 9MM
Most lead 9mm bullets are .356. Many plated 9mm bullets are, too.

I'm having some difficulty trying to do this. The cases seem to distort near the middle of the brass and won't gauge after being reloaded. The bullet is .356. Lyman "M" die used in this tool head..... I have several 9mm set ups w/ their own set of dies w/ different powders etc. all do the same.... I'm guessing it's the brass since it is range brass and who knows how many times it's been fired?. BUT , Federal F C nickel plated brass works better, no bulge and it will gauge most of the time ( rated +P). Looks like the case is stronger as it's +P?.. The only problem is, very hard to find. OAL is 1.12. To confirm my suspicions, Blue Bullets in 125,145 grn. are way better in range brass and most will Shockbottle. I do use a Lee "U" die in all tool heads, most brass is Case Proed. The only good thing, this is a revolver only load so I get back the brass
you might find this article of interest:
https://www.shootingtimes.com/editorial/reloading-heavy-bullets-in-9mm-luger/99514
if you're loading them for a revolver, you can have a very long OAL. like 1.200, 1.250, whatever you desire.
Do the ones that fail the case gauge still fit in the gun? The gun is the 'gauge' that matters.
are all power factors the same?
in 9mm/38 Caliber

Tests show that the recoil force is different with different bullet weights when using the same gunpowder. Heavier bullets produce slightly less recoil.
