After talking to Fox Ridge Outfitters in reguards to a new .54 Renegade barrelI found all the new barrels have this feature.[QLA]According to Precision Gun Works ,they remove a lot of them as they are out of square and throw off the accuracy.Any truth to this?In my mind a countersunk crown finished target style doesn't belong on a gun loaded from the muzzle end?Would appreciate any feedback pro or con.......experiences etc.Would also be HELL to load roundballs you would think? Thanx Harold
