Short barrel .357s

I carried and liked my 642 in .357 with 125 gr HP non +P loads in my pawnshop.

What I liked best was the muzzle blast. In practice at 7 yards indoor range, the blast would blow the paper target out almost horizontally.

Imagine the distraction for a bad guy if you did have to cut loose a SD round. Being INSIDE a muzzle flash could ruin your day. Not to mention the bullet.

:eek:
 
Yep, thats part of the fun for me and why I'm on the hunt for a SP101 in .357mag, although I'm leaning towards the 3" version.
 
'Non +p'?

Then you shot .38s out of your .357 and think it has muzzle blast?

That is no different from a regular J frame .38 snub.

Other than making a lot of noise you are only getting 38 Special perfomance from those short barrels. A 9mm in a comparably sized gun will actually hit harder and not be such a distraction to the shooter.

Lotta bark, not much bite.
 
Yep, I shoot snub nose 357s. The K frames are better than the J frame, but the J frame is the easiest to carry. The short barrel loads from Speer are my current "favorite" for all of them. The S/B 357 works very well. If that is too much for you try the S/B 38 +p. My previous favorite was the FBI load of the LSWCHP. (https://www.buffalobore.com/index.php?l=product_detail&p=108)

And an occasional 38.

I really laugh at the bottom feeder shooters that complain about how "snappy" the 40 S&W is to shoot.

woops.... 640

.357 mag 125 gr. No +P marking on case.
Was on CCW for years.
Good accuracy but I only qualified with .38s.

The .357 were for pawnshop over the counter range.
With the 38 qual running 290+/300 I figured I could hit at 6-8 feet. ;)

Unpleasant. But the muzzle blast wasn't blinding in the daytime.
Just hot, noisy and big.

good enuff
 
9mm out of a 3" barrel carries more performance than a 357 it of a 2.5" barrel? I'm listening.....

Not really more - but - the 9mm in a +P doesn't give up much.ground to a .357 snub.
One day as I was cleaning my S&W mod 66 w/2.5" barrel and also my Browning Hi Power,I laid the Hi Power on top of the 66 just to get an idea about overall size.
I discovered that they were nearly the same size & the Hi Power was actually a bit slimmer.
I went online and started looking at the 124 gr +P 9mm loads and found out there isn't a whole lot of difference between them and a 125 gr 357 out of a 2.5" barrel.
A bonus for the Hi Power is that it's worlds easier to shoot and has far less blast...plus it has twice as many rounds on board.
I traded away the 66 and never looked back.
 
The .357 magnum is a +P cartridge to begin with and they should not be marked either way. It is true that some loads are loaded lighter than others, however.

You do get better than .38 special performance out of a short barrel revolver. If shot from a shorter barrel, the performance of both .38 Special and .357 magnum is reduced. However, some loads of any handgun cartridge will perform better than others from a short barrel. That's not saying they perform better in short barrels than in longer barrels, though. Blast and recoil come with the territory but lighter bullets have less kick. Muzzle flash is not the same thing.
 
The muzzle flash and report from the short 357's are definitely impressive. My wife said she preferred a "wheelgun" so I purchased her this Ruger SP101 with CT grips and she LOVES it. She practices primarily with 38's, but when we practice with 357's it is any typical decent 110gr-124gr that we find cheap. What is kept loaded for SD and in a speed loader is CorBon 110gr JHP. I think that is going to hit as hard or harder than a 124 gr gold dot from my Sig P226.

Recently we were at the indoor range shooting several of our firearms. We started shooting the SP101 in 357. There was a cop next to us practicing that eventually leaned around the barrier and tapped me on the shoulder. He had a huge grin on his face, and told me that everytime I fired that 357, it was making his teeth rattle. It puts on a show for sure.

I don't feel under gunned with my sp101 carrying Hornady CD ammo. I'm also fine carrying my XD9sc with PowRBall ammo. I do prefer my SP though.

Sigh, the old ".357 from a short barrel is just a loud .38" myth that refuses to die. If we look at the data from Ballistics by the Inch (and bear in mind that they measure their barrels by the semi-auto method), we see that from a 3" barrel (actually closer to a 2" revolver barrel) that all of the 125gr .357 Magnum loadings are running at least 1250fps while none of the 125gr .38 Special loadings could even break 900fps from a 3" barrel. Likewise, the Cor-Bon 125gr and Speer 124gr couldn't break 1250fps until fired from a 5" barrel while the Federal Hydra-Shok 124gr only made 1250fps from a 17" barrel.

With heavy bullets, the .357 Magnum's edge widens. Both of the Federal 158gr loadings were over 1100fps and the Cor-Bon 140gr load and Federal 130gr Hydra-Shok were just shy of 1200fps from 3" barrels at 1172fps and 1194fps respectively. No .38 Special loads heavier than 135gr were tested and even then, none could break 1000fps regardless of weight. In the 9mm, the 135gr Federal Hydra-Shok required a 6" barrel to break 1100fps and the 147gr Hydra-Shok couldn't make 1100fps from any barrel length.

The only way you're going to get a .38 Special or 9mm to meet or exceed the ballistics of a .357 Magnum are to either cherry pick the most powerful .38 Special and 9mm Boutique loadings against the mildest .357 Magnum loadings or to compare the 9mm and .38 from long barrels against the .357 Magnum from short barrels.
 
Nice post Webley. Checking all of those stats out, I think I may give the CorBon 125gr DPX a try, see how it compares to the 110 gr.

From a short barrel, loadings with heavy bullets are actually the most efficient. This is because it takes more pressure to push a heavier bullet out of the case than a light one and thus a greater percentage of the powder is burned inside the case rather than in the barrel. This also means that, with a short barrel, a smaller percentage of the powder burns after the bullet has already left the barrel and thus velocity "loss" is typically less. So long as the recoil doesn't bother you, I'd recommend the 140gr JHP loading if you want to use Cor-Bon in a short barrel.
