Has anyone had problems with Sellier&Bellot ammo in 357 sig?. I took my new 32 to the range and averaged 1 mis-fire per 10 rounds. Had good hit on the primer, but no go.;P

I think you hit the nail on the head Clem.

After reading and thinking about it for some time now, I really think the .357 SIG is about the best autoloading pistol cartridge in the world. It's got high velocity and penetration in a small package with relatively modest recoil.

Well, I went to the range Sunday (12/12) with my Mod. 31. I shot two boxes of S&B, one each of lot numbers 43-12 and 43-17. The pistol functioned with Glock Perfection. No problems whatsoever. My Mod. 31 has all factory stock parts.

CZ model 100 with a Barsto .357 barrel installed: 0 shots from 20 rounds. Not one round lit, even after a second strike. (The CZ 100 has a DAO trigger with an internalstriker, allowing a second strike capability.) I added some preload to the striker spring (as much as possible) and it fired 1 round in 5. Stopped at this point as I didn't want to ruin anymore rounds in case someone else had a gun that could shoot it. I'll edit the post later when I get the ammo's lot number....

The gun does have trouble with other brands of .357 sig ammo, But nothing like this. With the .40 barrel in stalled, it runs everything I put in it.....and I've sampled just about every brand.

I'm beginning to wonder if the trouble is that S&B is made for tight chambers. In other words, since the round headspaces on the shoulder of the case, maybe unless the chamber is tight, the round is being forced too far forward so that the firing pin (or striker) is not being allow to punch deep enough. That coupled with hard primers might cause the problems noted.

My Mod. 31 seems to handle the S&B stuff pretty well (one (1) possible failure to fire in 700+ rounds). It was made in 1995 (it has a first generation type frame). The primers are probably a bit hard, but I'll bet it has more to do with chamber dimensions. Maybe Glock opened the chamber up a bit in its later .357 Sigs?

Now I'm not saying that Glock is making barrels that are out of spec. Rather, I'm saying it may be that Glock is making chambers on the loose end of spec while S&B is making its ammo on the tight end of spec. That may explain why the ammo works fine in some Glocks and not in others. Perhaps the Glocks in which the ammo works have chambers on the tight end of spec.

So, what do you think?

for $2.50 you can get a Extra Power Firing Pin Springs. from Glockmeister that's what i'm getting orderd last week. will be in the 27 that. way i feel in my primary carry Weapon.357 sig it will give me a lesser chance of a miss fire.

Since Christmas '04, I have fired four more boxes of S&B .357 Sig. in my Glock 31...2 boxes of lot 29-9, one box of 43-17 and one box of 44-10. No problems at all. Every round fired first time, every time.

Although I've never really had a problem in over 700 rounds of S&B fired, I went ahead and changed the striker spring to a Glockmeister extra power right around Christmas. I pulled the bullets on a few rounds of S&B and popped the primers with the regular spring and the extra power. Upon examination with an eight power glass, I could see that although the regular spring made a good strike on the primers, the extra power obviously struck harder. So, I figured since I had a three pack of these I ordered from Glockmeister during summer last year, I would leave one in the Mod. 31.

I've also shot 3 boxes of Lawman ammo since Christmas...it's very good ammo, indeed.

I have had primer problems with S&B 357. I was using my G24 with a 357 Bar Sto barrel this weekend. (I think there were several with my G33 also). I had numerous failure to fire primers. I would put them back in the gun and they would fire. Glad to hear this is a common problem. Thought my guns had a problem.

Yeah, that's what I'm changing over to...Lawman ammo.

I still have around 10 boxes of S&B and I've never really had a problem with it, but I really like the Lawman ammo.

I had 10 rounds fail out of a box of 50. I had purchased 2 boxes at the range, but I promptly returned the second box and exchanged it for Speers.

This is the only ammo my G31 has ever had an issue with. My only other failure to fire was a single WWB round.
