I have seen a number of double rifles converted to the 9.3x74r probably because of obsolete calibers or worn or damaged bores I owned an Italian double it was accurate but too light for the caliber any way I am only happy with English makes and am looking at them as I have a large supply of ammo. I would like to know folks experience with these converted rifles do they re=regulate them or do the rebores work like the original caliber's accuracy ,if anyone on here has one would like to hear if your happy
