.38 Super/Special?

[TwoPoundPull]

For easier insertion and extraction of moon clips in my 627, I'd like a shorter cartridge. Not wanting to use .38 short colt, I trimmed some .38 special brass down to .900", the length of a .38 super case. Case volume is within 1/2gn. using 231, (the trimmed special held a little more). There is more load data for the super than the short. Before I invest in .38 short/long dies for this "wildcat" cartridge, do we see any issues, and/or am I asking for trouble.

You shouldn't have a problem if you use the correct powder and bullet weight.

I went the 38 short colt route. I don't think anybody uses original old short colt loads as they were too low to begin with. I use 9mm loads in my cases. Around starting gr. Bought new cases from starline and new Lee's carbide dies. Everything is literally readily available to load. I've used 115gr, 124gr and 125gr. 9mm and 38s. There's nothing the 627 won't eat!

Easier loading- extraction. Worlds apart from trying to load 8 moonclipped magnums!

I think it should work out well. I'd be inclined to start with 38 ACP load data.

You can use your 38 special sizer and adjust 9mm dies for seat and crimp. If you have 9mm dies it cost you nothing, if you need to buy them they are less expensive or more common used anyway.

Tried Short Colt, and just wasn't comfortable with pressure using my favored 160 grain bullet.
Going to .900" (AKA 38 Mid) worked out just fine.
I use the thickest (.025") moons, along with Federal or Remington cases that fit best.

Why not just use super cases?

They'll probably fall out of the speed loader.

 

[TwoPoundPull]

Super cases don't fit the cylinder.

I have the same gun but not a comp shooter, but is the reason for this to aid in loading the clips into the gun faster? Speed up the reload? So they are not dangling around??

To be honest I hate clips even though I have nice loader and de mooner. It's like loading a gun twice but understand if it is for competition.

 

[TAROMAN]

The 357's case length makes them wobbly in clips.
Remember that clips were first made for .45 ACP that has that big extractor groove. This allows for sturdy clips and short rounds make loading easy. And that .45 cylinder is mostly air. Just watch Jerry Miculek in action.
After one match with the TRR8, it was obvious that something better was necessary. The issue was thoroughly aired on a popular competition forum, with short(er) cases being the final solution.

1) .38 Super is loaded to higher pressure, so I hope you aren't asking about using .38 Super load data
2) If the COL is the same as .38 Spl, the load data is the same. If the COL is shorter, than you are on your own and should at least look at data for a cartridge of the same or shorter length
3) Amazing that since 1908, clips have worked well enough in revolvers that I never heard this complaint. I have heard such about speed loaders, but RN bullets were the general solution.
Since it sounds like a universal complaint, there must be a standard "solution" out there that has already been tried and tested. If not, be sure to share your results with Jerry and the rest.

.762 case length short colt case vs. .754 9mm case.

You can safely load 38 shorts at starting 9mm loads. I do. These are yesterday's cases shooting a 929 9mm and a 627 38/357- shooting 9mms out of a short colt case.

I shoot more shorts now than magnums or specials. When shooting 500 rounds/hour, having those shorts just drop in helps. Longer cases don't help.

The issue I sometimes have is extraction, cases not clearing the cylinder, especially when chambers get a little dirty. It's a non-issue with the 986 and short 9mm brass.

 

[BLUEDOT37]

Super cases don't fit the cylinder.

LOL, I figured you could resize it with a 38/357 sizer & it would fit but I just tried it and the 38 Super case ends up with a ridge near the web. Maybe if they made a push-thru sizer for it?

38 Super = .384" vs. 357 Mag = .379" OD

Whats funny,

I just tried a new .38 Super brass in my .38 special, and a loaded Super...

BOTH FIT!!!!

The proper moonclip should also be available... From .38 auto to 9x23 theres LOTS of load data.

(could be the Starline brass too!!)

My empty 38 Super cases didn't fit in any of my 357s. That's funny.

I have eight .38/.357 revolvers and some will accept ACP/Super and some won't. Those that will, will only accept new unfired. None of mine will accept fired or resized. Haven't tried resizing in .357 sizer, but would expect same result as BLUEDOT37 got.

This is the reason most comp shooters go to the long colt or short colt, the stroke off the ejector rod is not long enough to push the cases all the way out, so they use shorter brass. This helps with faster reloads and quicker ejections of spent/part spent moonclips. With short colts start with coresponding 9mm start loads of the the same weight and work up, for long colts start about mid way loads for 9mm and check for power factor with chrono to get up to where you want to be

I load .38 SC with normal .38 Special dies. I don't need a 9mm seating die, but maybe it's just my dies (I don't crimp). As noted, SOME .38/357 revolvers will chamber (and fire) SOME brands of .38 Super ammunition. And of course you could size .38 Super brass in .38 Special dies for revolver use so that wouldn't be a problem assuming the moon clips would otherwise work OK with them.

I find .38 SC to be ideal for use in snubby .38 Special revolvers - fired brass extracts completely when .38 Special brass won't.

I have some Starline cases and the Lee Short Colt Die set ordered and on its way with using them in my 642 in mind. Are you using the 9mm loads as your starting point? Any advice on powders and bullets you've had luck with in your J frame would be greatly appreciated.
