Hi Guys. I just had to have my FA .454 Casull's barrel replaced because of forcing cone erosion. The only bullets I've used have been the FA 260 grain when they made those and the rest have been Hornady XTPMags. I use the proper weight of W296. Has anyone experienced this with your FA .454? I spoke with John at FA and he was very helpful 'd be interested in what lads folks were using and especially what bullet. Thanks

yosey, I hav`ent had forcing cone problems with my FA`s 454 but couple of guys here had them by using Lil Gun powder in their handloads.... now you`ve got me thinking because I`ve had my 454 for 25 years and I have to check the cone... How did you know there was a problem with your gun??

James, I noticed the erosion while cleaning. My gun has some age on it. I believe it was made back in '90-91. Haven't shot it a significant amount, maybe 400 rounds over the years. For a while all my hand gun hunting was with contenders (6.5JDJ, .375JDJ, .45-70SSK, .35 Rem.SSK).I have stuck pretty much to W296 for my hand loads and FA bullets or Hornady XTPMags. I noticed the erosion last fall. It still shot very well, but I was concerned about safety and that's when i sent it back to FA.

YOSEY12: BEEN OCCUPIED GETTING READY TO LEAVE FOR ALASKA ON 5/24/19 AND TO GO TO MY RANCH ON 5/16/19 SO HAVE NOT PULLED OUT MY 5 FA 454's TO CHECK FOR FORCING CONE EROSION. DID CHECK MY MNP "PRACTICE" STALKER AND IT LOOKED FINE. IT HAS BEEN REBARRELED ONCE BUT THE CULPRITS PROBABLY WERE LIL'GUN POWDER AND/OR XTP BULLETS (THE NON "MAG" XTP's). BACK WHEN FA MADE BULLETS THEY EMPHASIZED THE IMPORTANCE OF HARD BULLETS, BUT AFTER FA SOLD THEIR BULLET MAKING MACHINES THEY JUST KIND OF QUIT EMPHASIZING "HARD" BULLETS. IN A PDF HANLOADING AID FROM FA, STILL AVAILABLE ON THE INTERNET, THEY STATE THAT HIGHER VELOCITIES AND SOFT BULLETS BOTH ACCELERATE FORCING CONE EROSION. LIL'GUN WAS ALSO A BIG FORCING CONE EROSION CULPRIT. I HAVE OFTEN WONDERED IF THE XTP MAG BULLETS ARE "HARD" ENUFF, AS I HAVE MY DOUBTS THAT THEY WOULD BE, AND I SHUDDER TO THINK OF THE HARM GUYS MAY HAVE DONE AND MAY BE DOING TO THEIR BARRELS WITH 240 MAG XTP's IN 454's AND 460's.

I THINK YOU HAVE 3 POPSSIBLE CULPRITS: 1) YOU USED LIL'GUN BUT HAVE FORGOTTEN YOU DID; 2) HV LOADS WITH THE 260's; AND/OR 3) THE XTP's. ONE OTHER THING, I DO NOT KNOW HOW BAD YOUR EROSION WAS, MAYBE YOU DID NOT NEED TO REBARREL? FA IS NOT GOING TO TURN DOWN A REBARREL JOB, SO WHO KNOWS.

I "ASSUMED" THAT THE GUN WAS BOUGHT NEW AND ONLY HAD 400 ROUNDS THRU IT, IF IT WAS BOUGHT USED WHO KNOWS ITS HISTORY.

45MAN, your assumption is correct. It was bought brand new and I have never used Lil'Gun before. Maybe it was the XTPmags. I gave FA my load information and they said it should be ok with the xtpmags. I have 50 or so loaded up now and I am concerned about using them when I get my gun back. I may skip them all together and just use factory loads for a while.

Yosey, Your right about not shooting your gun much.. you said it was made in 90-91 so its about 29 years old and you bought it new shooting only 400 rounds. That`s not much at all.. What did the erosion on your gun look like?? My FA 454 is 24 years old and I really don`t know how many rounds I shot with most of them being factory or factory equivalent handloads but I can say I would handload until I filled a coffee can for a range day. 99.9% were jacketed bullets. The tiny knicks I mentioned above are the only thing out of ordinary.. Maybe Rey was right saying you may have forgot using Lilgun cause that`s the only way I can see eroding the barrel with 400 rounds...
