Default is 125 grain ok?

i have a ruger service six 357 magnum, it has a small flame cut above the forcing cone. i was told light bullets like 110 grain causes this, i recently found several 158 grain federal soft points but got a great deal on 125 grain remington soft points. will the remington's be ok? or should i just stick with 158 or larger grain? thanks

The flame that erupts from the cylinder gap on revolvers is akin to a cutting tourch. I can attest to the cutting power of the cylinder flash as I carry a tattoo from a S&W Model 19-3 on my left index finger from a malfunction with .357 mag loads circa 1974. The hotter loads, regardless of weight, will accelerate the cutting on your revolver, so I would shoot it and enjoy it till it needs attention.

I have one of those, for practice I use 125, loaded light-medium pressure 38spc. 125 shoots a bit lower, the fixed sights on these tend to be regulated for 158. using primer with xring rubber bullets will reduce a lot of the cutting, other benefits too, but that's up to you.

Your going to get gas cutting no matter what you do. Its how it is with revolvers. Light vs heavy bullets isnt going to make any substantial difference.

Its a main reason i use ruger revolvers they hold up the best to heavy use.

these are remington umc 125 grain soft points box of 50. i can get several boxes at $15 a box from a guy who has went to an auto and doesn't want them. just wanted to know if they are some of the one's that might cause flame cutting as i was told that the 110 grains were bad for that. the federal 158 grain soft points were $26 a box at my local store so i'm saving some money if the remingtons are ok. thanks

They are fine. All cartridges regardless of weight cause flame cutting even in semi autos and rifles. Its a normal function of igniting cartridges. Shooting damages guns.

One type of cartridge isnt any better or worse in realistic terms than another in the same caliber.

Pressure causes this effect not bullet weight. The more pressure the more wear. Its true of any cartridge. Just inspect for cracking if its a concern to you.

From what I've read (by no means gospel):
Supposedly flame cutting is worse with the lighter bullets...125s included. That said, the whole "lighter is worse" theory never been explained to me in such a way that it made actual sense. (To be fair, I could just be a bit thick.)
My opinion:
A high pressure flame (30K+ PSI) is a high pressure flame. Not really a lot of nuance in the process. Near max pressures are going to cause erosion, regardless of bullet weight. In my admittedly non-expert opinion, I suspect that bullet weights don't make as much differences as say, dropping the pressure with lighter loads. FWIW, my 627 shows evidence of it even with a diet of mild (for .357 spec,) cast reloads. I suspect that the only way to avoid it completely would be to leave it in the safe.

FWIW, I suspect that even with full strength loads, your Ruger will probably outlast us all.

If you are really worried about further flame cutting, or want something quieter, no recoil for practice or introducing new shooters and teaching safety, then I recommend trying these: http://www.midwayusa.com/product/713633/x-ring-rubber-bullets-38-caliber-357-to-358-diameter-box-of-50
Just a primer, case with widened flash hole and these. The cases dont seem to wear out with these, i love em.

i have to agree with Jon. it's not the bullet weight that matters, but the pressure. hotter loads equal higher pressure so there is the increased wear from flame cutting.

and every revolver is going to experiance this flame cutting to some degree.
