Hornady .357 158 Gr XTP Ammo Jams My New 686!

[686-380]

After many months of consideration...

I have been firing all kinds of different ammunition, probably about 300-400 rounds. Factory Hornady 158 XTP is the only ammo that I have trouble with...but not nearly as much as when I sent it back to the factory.

I discovered the ammo that I prefer for home defense and probably won't be purchasing any more of the 158 Hornady XTP...

Your recent post reactivated this "zombie thread." My thoughts:
1. Under no circumstances use that troublesome ammo again. Ever. It may function properly in everyone else's gun. That it doesn't work in yours... Season's over for that round.

2. Taking .357 factory ammo as an example, in the 1950s and 60s, there were very few factory loads available: a lead SWC and a jacketed "metal-piercing" load. Remington offered a JSP load. That was it. Since those early days, probably 100s of different factory loads, and different generations of loads have been produced. Also loads imported from foreign mfgrs. Not to mention "factory loads" from smaller-volume local mfgrs. The possibility of a given load causing problems in a given gun is greater than it used to be when there were only 2-3 loads available.

3. The moral of the story: Extensively test a given round if one is considering it for SD. Good luck. Wish you well.

First I would check the chamber depth. The fatter ogive of the 158gr can expose the problem. Don't tailor ammo for the gun. That's a semi-auto thing. Your gun is defective, and just hasn't been figured out yet.

I thought that the change in threading of the ejector rods back in the ... early 60s(?) put a stop to them backing out. This sounds like something else.

My 1998 686+ has had the ejector rod back out several times. Then I put some loc-tite on it. Never again since then.
