YOSEY: WHAT WERE YOUR LOADS WITH THE FA 260's AND THE 300 XTP MAGS? HOW MUCH 296 WERE YOU USING?

improperly heat treated barrel? poo happens. I'm going to take him at his word, new gun, 400 rounds, and no little-gun. no offence intended, do you know what your looking at? i've been shooting revolvers for 40 years and wouldn't know a eroded forcing cone unless it looked like a washed out gravel road. keep it coming i find this vary interesting.

All I'm saying is if you encountered forcing cone erosion at 400 rounds, I'd send it to the scrap pile.

Pay that kind of money for something and this happens with a low round count? Screw that.

Can you provide a picture? I just can't see it eroding with that few rounds. Even if it was junk steel.

Don't mean to sound like a prick, but I find this odd.

I sent a picture to FA and the gun itself and they said it was the forcing cone. Right at the beginning of the barrel where the bullet jumps from the cylinder to enter the barrel used to be a smooth ring. Now the inside of that ring is jagged and looks eroded. Don't know what else to say. I've had the gun for many years, but there have been stretches where I haven't shot it for multiple years. My load with the XTPMags are 300 gr xtpmag and 27 gr W296. The 240 gr xtpmag is loaded with 36 gr W296. I thought this was hot enough, but maybe I'm not using enough powder.
I'm not trying to blame anyone here and certainly FA has been very good to work with. I'm just trying to see if anyone else has had similar problem.

YOSEY12: I JUST SENT YOU A MESSAGE WITH MY CELL # AND EMAIL, IF YOU WILL TEXT OR EMAIL ME THE PICTURE(S) OF THE EROSION I WILL GET THE PICTURE(S) POSTED FOR YOU.

MAYBE THE CULPRIT WAS THE 240XTP's.

I have totally roasted my forcing cones and the face of the cylinder in my FA's and they still shoot little tiny groups at a 100 yards...So don't overthink this as a "problem that you need to throw a bunch or money at "unless" the gun won't shoot.
My 454 was pretty bad. And now I have around 9,000 rounds through my 475L and it looks like the forcing cone was cleaned with a triangle file.

Remember the original FA83's used to come with a replaceable forcing cone because they are so hard on them.

I can't help with the cause for your cone erosion. I have ruined two barrels in FA 454's but they were due to Lil Gun. I was advised to switch to 4227 powder as it would be easier on the forcing cone than any of the ball powders. Velocities are not as high but accuracy has been great. 4227 is also less temperature sensitive.
