Ash ,go have a lie down on the couch until the Feeling passes ............
B. buy a Ruger No1 ,and have it rebarreled to a 585 Hubel Express by Allan and Grant Swan at Redbank ,Ed Hubel will give you all the advice you need, brass is made here in Australia ,you will have 577 ballistics and much more if you want ,none of the problems with regulation and none of the annoying hassles trying to get a bolt rifle to feed properly ! and much much cheaper than a 577 double !
