Default .357 125 grain JSP

Last week I bought a box of Remington UMC .357 125 grain soft points. They are rated at 1450fps just like the SJHPs. This load unusual to me, as most JSPs are 158 grain. The old Remington catalogs say that this load was desinged for law enforcment. Does anyone know how well the JSP bullet performs in this 125 grain loading?

It is a non-expanding load, just like the 158 gr JSP. They are good for practice or if you need a non-expanding bullet for extra penetration depth or if you are somewhere that forbids the use of hollow point ammo.

They are fantastic for deer, especially from a rifle. I have no experience with that particular ammo, but i use 125gr semi jacketed soft points to reload for my deer rounds. And yes, they do expand. Hope this helps.

Years ago the FBI determined the .357 Magnum 125 gr HP was the best manstopper ever. Considerable bullet development has been done since. These tests led to the creation of the 357 SIG (no decimal point) (TM). But now the ballistic ghods of the FBI have determined Hornady 9x19 mm is just as good and cheaper.

Psweigle,

What brand of JSP have you used? I have been using the 158 grain XTP in a .357 with good results but might want to try the 125s. Do you get "pass throughs" on broadside shots? Thanks in advance.

Remington has offered SJSP, JSP and SJHP loadings for the 357 Magnum cartridge in 110 grain, 125 grain and 158 grain going back almost half a century now. It is just more common to fins Hollow Points stocked on the gun stores shelves these days

The Remington/UMC JSP loading in 125 grain is a nice Performer.

As already stated a JSP does not expand as much or as soon as a JHP of the same weight and construction. However, JSPs absolutely do expand. If you are in need of a non-expanding load than you want to use a FMJ

JSPs are usually better suited for taking game as opposed to personal defense. Unless of course you need to shoot through a door

I have chronographed this Remington factory load from many different firearms. Most velocities listed below are from 2 or more strings of five shots averaged from 2 or more different examples of the same model firearm

From the 2 1/8" Model 640 this load hits an average of 1242 FPS. Not too bad for a pocket gun

The 2 1/2" 19/66s hit 1287 FPS

The 3" Model 60 Pro yields 1298 FPS while the 3" Model 60 Small Hunter gave us 1322 FPS

In the 4" Model 27 it averages 1391 FPS.

From the 5" 627s this hit 1496 FPS as the average

The 10" T/C Contender hit 1776 FPS.

Someone mentioned a rifle. In a 18" 1892 lever action the round achieves 2049 FPS

So the factory claim, is not too far off from reality

I also hand load the 125 JSP in the 357 Magnum Cartridge.

This is one of my favorite weight projectiles to shoot. Over the decades I have gone through many tens of thousands of this load in various firearms.

Actually, the FBI did not make any of these determinations. The FBI only compiled the statistics from actual shootings and let the results speak for themselves.

The Remington 125 grain SJHP has always been the #1 best single shot, man-stopper on record.

The only reason that the 9MM and other calibers have been gaining on the Remington 125 grain SJHP's reputation is that LOTS less Law Enforcement Officers are carrying those Remington 357 Magnums these days.

So the actual count of firefights that are stopped by 9MM has increased over the last few decades while the number of 357 Magnum firefights has dwindled away to tiny numbers

Yes, projectile design has improved over the years and that has gone a long way toward the re-acceptance of the 9MM Parabellum cartridge for use in the Law Enforcement world. However, you must remember that those smae projectile improvements have been applied to the 357 Magnum and other projectiles improving their capability as well.

Where's your reference for this claim.

It's the first I've heard of it.

The SP design bullet is a very good hunting bullet and with enough
fps, it will expand on deer size game and really go to a large Dia. if it
hits a shoulder or main bone.


The little 125gr SP does well with its high speeds for small game and 200 yard "Yotes" if you can get a shot off.

Some revolvers shoot the SP design better than the JHP.
You just need to see what your weapon likes but the SP is usually
cheaper in price, which is a good thing.

In my 686 6", I wind my 158 JSP up to 1340fps for deer or larger animals that need shooting.
