.357 Sig Bullets

[Billboard]

Yesterday i was looking around and found these bullets Everglades Ammo.
They are 9 mm 125gr .355 JHP. They seem to have a longer neck. Has anyone used these for the .357 sig ? Only got 100 just in case.

By looks, they're similar to Hornady's XTP. I would think they would work.

The butt looks much like Precision Delta's 124 gr. JHP. They're almost a clone for the XTP.

Billboard, you did not mention which launching platform you're reloading for but... The .357 Sig is one of, the if not THE most forgiving cartridges of various bullet styles I've ever loaded for in 40+ years of reloading. I started reloading the Sig since it was first available in the Sig P series pistols.

I have even genned up batches of .40 re-formed brass (with the characteristically shorter neck) with 158 grain .357 mag bullets re-sized to .355 and they work perfectly. Currently I'm using home cast 139 LRN that I've powder coated which also work flawlessly in Sig and 1911 (ramped bbl) launching platforms.

I wouldn't call the .357 sig to be the most forgiving of different bullet styles. Neck tension and bullet setback are of concern when loading it. With that being said, most folks will bell the neck to the absolute minimum possible and still be able to seat the bullets. As long as there is enough base to the bullet so that you can seat it and not get setback you should be fine. I've had good luck with 124 grain RMR TC, RMR MP HP and MG HPs. The bullets you showed pictures for look like they should work as they look to have enough base.

I use RMRs 124gr FMJ-FP "matchwinner" in .357 Sig. It's a staple component for range loads and woods carry. Has to be set to 1.140" OAL or just over to work with the case length. Those look pretty similar, but I have no personal experience with them.

I disagree and found it one of the more challenging pistol calibers to load. A good bearing surface with no taper is what you're looking for - very generically more the shape towards the base of a JHP vs a FMJ 9mm projectile. What you have pictured looks good.
I did not find it forgiving of bullet profiles - quite the opposite loading for a P229 - but I was chasing lengths on some for reliable feeding where a typical (non-Kimber )9mm usually doesn't much care about round nose, truncated cone, JHP, etc - fairly close and they eat 'em up. .357SIG not so much

.357 Sig! cool round

I didn't say "to load", I meant to feed... I said..."they work perfectly" If you had a problem in a Sig, not me after many thousands of rounds (P229 and P226) not only in Sig but in 1911's.

Loading is no real biggie either... size with .40 die first, lube case neck, size neck, seat, crimp, clean the case.

Anyone who has loaded rifle cartridges should have no issue, unless they just want to whine it's not as easy as a 9mm, .40 or .45. Then I guess it is a challenge.

Call me ignorant but you ask what reloading platform im loading for? First time im asked that what do you mean?

Handgun, firearm, gun, Launch bullets?

Bullet choice has always been an issue for .357 SIG, compounded with loading in a progressive press.

When on a single - stage press, you see and feel exactly what's going on, and don't need to bell the case lips as much (me - not at all!).

 

[Billboard]

Im using a RCBS Rock Chuckler Press. Been using it for 7 years now and i like it. Load for
40 sw. , 45 acp , 300 win mag, .556/223 , 9mm , now .357 Sig. Thats about it. I would like a lever action in 44 or 357 and 45/70. Those are soon to come. I thought thats what was meant but just wanted to be sure.

My 357 sig is a fnx40. I bought a conversion barrel for it. So i can shoot both. I also have a fnx 45 , hk p30ls 40sw, hk45c

Those bullets in the O.P. would work just fine in the 357 SIG ... it has the proper profile ... long bearing surface is not needed ...just that bullets that work well have that profile because of the neck location of the cartridge ... otherwise the ogive of many bullets will be inside of the neck with nothing to hold the bullet in .... try a regular old round nose seated to the C.O.A.L. .....the bullet will fall into the case....

The Hornady 124 grain is the perfect profile for the SIG .... any bullet of similar profile will also work ....

Except you don't really have to worry about bullet setback when loading for rifle. Except for AR and then you will be crimping.

The .357 Sig is one of, the if not THE most forgiving cartridges of various bullet styles I've ever loaded for in 40+ years of reloading.

You did say it's one of the most forgiving cartridges you have ever loaded. I personally don't agree with that and I've loaded over 50K of 9mm, 10K .40 and around 5K .357 sig and plenty of rifle as well. It's not that it's "hard", just you have to worry about bullet setback and neck tension and not all bullet profiles and shapes will give optimal results if you care about bullet setback.

And it is forgiving to load in every respect, except for those who don't take time to understand what they're doing.

Anyway, I think I had ONE setback since day one, I can only guess you're doing something very differently than I am. It's NOT hard to load, though it does take time and it does NOT jam. You've found a radical departure in loading than what I've found. In your case, there's the 9mm which with 50k loaded without what I would assume you have not had a single issue. Dump the Sig if you already have not.

Those bullets look good to go. Check the diameter since it is neck tension, neck tension and neck tension. If the ogive is outside the case, and it fits in your magazine, and it passes the plunk test, then you are good to go.

At some point you should try some 147gr bullets in 357sig. Especially the RMR 147gr bullets seems to create a better neck tension, and 147gr for me is easier to load in 357sig than in a 9mm case.

That’s exactly what I’m planning on doing. Been using 125 gr Montana Gold but want to move to the heavier 147’s. I have ~500 147 gr XTP’s I’m using for a Kel Tec Sub 2K 9MM loads and plan on getting more for my .357 Sig load development

For me, CFE Pistol seemed to be very accurate using the 147gr RMR TCFPMW bullet.

 

[The Glockodile]

Montana Golds, Precision Deltas, Hornady HAPs in the 124 - 125 gr weights are good...

I seen that. I can wait for better pricing.
