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
