I just ordered some 115gr 9mm Zero JHPs per the advice from the reseller I purchased them from. I plan on loading them up in 357 sig. Has anyone loaded this particular bullet in 357? How about any 9mm 115gr JHP? I sent an email to Zero and corresponded with a helpful service rep, but she said the only Zero bullet designed for 357 sig was not the bullet I ordered.

Now I'm wondering if I made a mistake.

Thanks.

Only see 3 bullets in that size & weight on the Roze website. All 3 look like they'd load just fine for a 357 Sig.

Let us know how you do,

I have some Zero 115 Gr JHP (#162) 9MM bullets and after some quick measurements they seem to have enough full diameter shank (.3555) to work in .357 Sig, but I do not know. I do not load the .357 Sig.

I have used both the 9mm and 357 zero bullets and they work fine. Don't have a 357 SIG but took apart some old ammo and used the bullets in my 9mm as they measured the same size/weight W/O problems.

Thanks for the replies, I'll update the thread after I give them a try.

I read that some of you are using the Zero 125 in the 357 Sig, but I have a question.

I don't reload 357 Sig, but I thought the 357 Sig had a slightly "longer" bullet.

If so, would seating on the case cause a bigger 'jump' to the rifling when you load with a 9mm bullet?? Any COAL/seating depth problem with doing this?

The problem with .357 sig is not diameter, its ogive. I've loaded a few hundred with 124GR. Rem JHP. I have to load them .006 longer to prevent setback (1.146), but that works for my Sig P226.

I found this link that have been very helpful.

There is a lot of B.S. out there on this caliber. Lyman's newest handbook was very helpful as well.


Good luck.

Very true, but doesn't go far enough. The REAL problem is the short neck of the 357 sig. That short neck HAS to grip the full diameter of the bullet to insure it can't be driven deeper into the case.

The long taper of most round nose 9mm bullets, sits way down into the case, barely getting gripped by the neck. An accident,(KABOOM, waiting to happen!

My bullet of choice for my 357 sig handloads is the 125 H.A.P. bullet from Hornady. Hornady Action Pistol. It's their 124 XTP bullet without the internal skiving to make it expand. The stubby TC configuration makes the full diamet actually come out ABOVE the front end of the neck. Very good accuracy, at reduced cost.

montana gold also makes a bullet specifically for 357 sig. works like a charm.

Below is a picture of 6 loaded rounds using different bullets that I have fired. From left to right; Montana Gold 124gr JHP, Hornady 124gr JHP, Zero 115gr JHP, Remington 124gr JHP, Buffalo Bore (factory) 125gr JHP, and finally, Berry's 124gr FP. All of the rounds are seated to 1.140 with the exception of the Berry's, it is seated at 1.120. I did not measure the max diameter of the Berry's or the Buffalo Bore bullets but the others measured .355 on my caliper

I tried to reread the thread with the photo... I thought you had reloaded those ...

I'd like to share with you the bullets I have used and some information regarding them.

Did I misread that you had already loaded some of the Zero 115 JHP? Or was that a different bullet that you loaded in the photo.

Yes, I did reload these and have shot many. I found this old thread that I started a while back and noticed that I said I would update it once I tried the Zero's but never did. (update that is). Sorry for the confusion, the picture thread is 100% correct.

Sorry I did not read the thread date, my fault.

I know that we had just went through that thread about the various 357 SIG bullets.

So have you found others besides the ones in the photo that have worked for you?

So far I been able to get Hornady xtp that work well in my 357 SIg, like I said in the other thread the Gold dots work well too.

Jim,

If you've had good luck with the XTP's I think you'll like the MG bullet just as well. Maybe even better because of the bulk pricing. They seem to be twins in design, both being TC profile bullets. The other 3 I've tried are conventional style with the rounded ogive.

I haven't come up with any accuracy data yet as I am just getting started with this caliber so I haven't decided on a favorite either. Price wise, you can't beat the Zeros though at $83 per K. I'd like to try the Zero 125 gr JHP's assuming the profile is the same as the 115's. They should work also. Maybe when I run out. :)

I haven't tried anything except the 125 Gold Dot and 124 XTP. I had purchased a good amount of XTPs before the shortage began, so I had plenty to hold me over. I still have several hundred left. I had purchased a 8 pd keg of AA #9 and had quite a few Rem. SP primers that I had got from a estate sale, so I was OK with those.

The XTPs shoot darn good, better than I can! I haven't ran any over the chrono so I can't say how they are velocity wise, but I think somewhere just over 1300 fps, I got to get out and do that. The Gold Dots(all out of those) shoot very well too, about the same as the XTPs. I have shot some those over the chrono, don't hold me to it(my notes are out at the reloading shed), but I think they were Avg. 1365 fps over 13 grs of AA#9. AA#9 is the only powder that I have shot to date, I do have plenty of Win. 540(HS6), 800X and a can of Power Pistol to try, I just haven't got to it yet.

I have read that the SIG likes 124 gr. and 147 gr. bullets better than the lighter 90 gr. and 115 gr., I have no proof of that, just something I read.

I would love to try the 147 Gr XTPs over 9.0 gr. of 800X for 1317 FPS ... from Hodgdon web site.

I will give the Montanna Gold and Zero a try soon, sounds like a good bullets. The price sounds good too.

Good shooting!
