Actually, I think the primer bulges and flows before it can start sliding.

Thanks again, Flopster.
You're most welcome!

~ But, I assume this is only a problem when firing .357 mag.?
It doesn't happen with .38 Sp., does it?
Also...my shootin' iron is a 686-4, so I'm safe with the bushing hole.
I'm no authority on this stuff, but I would think it would take some very serious doing to have such trouble with .38 ammo. The load that caused my lock up was R357M1 (Rem. .357 125 gr. SJHP). A load like that runs at much higher pressure and would use a case full (maybe a compressed charge) of slow burning powder as well a magnum primer. It's just a whole different animal.

Also of interest was that forum member Nitesite had some ammo from the same lot. He had previously started a thread about the very high velocity he got with his 6" Ruger with that load. IIRC, it was nicely over 1600 fps. and around 730 foot pounds The folks at Remington tested my problem ammo and said that the velocity was out of spec./too high. That doesn't necessarily mean that the pressure is out of tolerance, but I certainly wonder if it was as well.
