Using Winchester 110 gn 357 mag ammo in 686 stainless steel revolver.

[MCMXI]

the more powder you burn the sooner the damage can occur, and most lighter bullets use more powder than heavier bullets, at least in reloading with canister powders.

That's a valid point too, particularly for the reloader. I don't know the charge weight of the Winchester 110gr ammunition in question but the advertised velocity is basically the same as Remington's 110gr. We can probably assume that both loads use similar powders and probably have similar charge weights.

My 340PD has No less than 120grn bullets on the shroud.

500 of the Winchester 110 gn 357 mag ammo has now been shot through the Ruger LCR 357 revolver with no sign of gas cutting. The top strap still looks like it just came from the factory. The machining marks that run perpendicular to the top strap appear consistant from the recoil shield up to the forcing cone with no sign of metal loss. I guess this tells us something. Thanks for all the input.

I have put hundreds, if not more, of 110 gr. and 125 gr. full house magnums through my SS revolvers. They all exhibit some gas cutting of top strap, but this is typical of any revolver, and is normal wear and tear. Do 100 gr. and 125 gr. full house magnum loads that are loaded with a large volume of powder, such as H110 offerings, of course. More powder means, more super heated gases making contact with the strap.

As for forcing cone damage, I have run thousands of rounds of full house H110/296 magnums through my S&W "K" frames, and none have any damage what so ever to the FC's.

So no, you won't harm your S&W by shooting those through it. A steady diet might increase the visible cutting of the top strap though. But it's also safe to say, that you couldn't possibly shoot enough of any full house factory or published loads through it to create a safety concern, gas cutting only goes so deep, and then it stops.

Be advised that if you shoot a lot of 38 specials first you should not then shoot 357's after that before cleaning the chambers. The reason being is that you will develop a ring of fouling commonly called a "crud ring". If you then load the longer 357's the ring will constrict the expansion of the 357 brass, and can increase the pressure to undesirable levels as well as lead to sticky extraction.

I've put 150 rounds of 38's through first and had no problems. One of the other gents will likely chime in with more info as to how many 38's are "too many" before 357's in the same session.
