Model 27-2 forcing cone erosion

[SGT ROCK 11B]

I picked up this 5" 27-2 from the original owner a while back. He said he bought it new in '73 (S/N N166164) and only put 200 rounds through it ...

Most sellers do not tell you the real numbers of rounds down range. Also a seller will not tell you how hot his reloads was; since he is a Handgun Hunter and he was loading for a Bigfoot Hunt.

Ya, but everyone knows you need to use Sierra's 170 JHP if your using a 357 to get the penetration and expansion needed to put a Bigfoot down. I am sure I read that on the internet somewhere, so it must be true. This was advised, despite the fact that someone's grandma killed one using 22 shorts in a Stevens Crackshot

So, I decided to go with the barrel swap. It's been a while since I've owned a 3 1/2" 27 and although this one's not an original, I have to say, it's pretty cool. Not sure what I'll do with the 5" barrel.

If you are happy I am happy for you. I would also be happy to give you $10 for the old barrel. Might even go $20 and I would pay for shipping.

By the way, that 3 1/2 looks seriously BAD.

I think you have a 50+ year-old revolver that has been shot a fair amount; it also has moderate flame cutting under the top strap. My guess is a slow, hot powder with lighter weight bullets (110 and 125 grain). The erosion is there, but doesn't extend far on the back surface. I wouldn't worry about it, keep shooting it if it's mechanically sound. Refrain from lightweight bullets. They are shorter than heavier ones and even a fast powder is still burning when the back of the bullet passes the B/C gap. The flame front hits the rear of the forcing cone and top strap above the B/C gap. Measure your gap and check the cylinder for end play. Excessive end play can widen the gap.

My first 27-2 lived on 110 gr Winchester White box,, flame cutting of the top strap and erosion of the forcing cone, all part of thee fun... I'm a 158 grain man these days.

That type of erosion is worse with ball powders. In a hot load, the ball powder is sandblasting the forcing cone every shot. Flake powders will do it eventually, it just takes longer.
