[QUOTE="J E Custom, post: 282717, member: 2736"] Yes it is the barrel !!!!! I don't know where or if they bough the barrels for the Coyote but they are bad. I have been asked to save more than one and this is what I found= While getting setup to lap the barrel (A last ditch effort to save it after every thing else failed) I have found that every barrel so far has had tight spots down the bore. The worst had 5 places that the broach tryed to hang up they were so much tighter. I lapped these areas until the restrictions were removed and then cast a new broach and finished lapping the entire bore. This much lapping can reduce barrel life so it is not recomended except to save a barrel that will only be hunted with and a minimum number of rounds (800 to 1000 rounds). The calibres that I incountered this problem with were= 223 WSSM,6mm WSSM,25 WSSM and 325 WSM. That does not mean that other calibres were allright just that these are the ones I was asked to fix. I did not find much else wrong with the coyote rifles except the bedding job that winchester attempted was worthless. The worst one would shoot about 4'' groups at 100yrds and after lapping and bedding it shot 1 to 1,5 MOA (good enough to hunt 2 or 300 yrds. I would recomened that you get your smith to re,barrel with a good stainless barrel in the same calibre and do a full bed and float on the stock. J E CUSTOM [/QUOTE]
