I've got a couple of older rifles, a Winchester M70 "Heavy Varmint" and a Tikka M595 Master Sporter from the 1990s that are both tack drivers. I recently got my first suppressor and as I was warned, I now hate shooting anything without one. So I am considering having the muzzles of these two rifles threaded. Assuming the work is done correctly by a skilled gunsmith, is there any reason to fear that the accuracy of the rifles could be negatively affected? I know the POI will change when using the can, but that doesn't bother me since it's easily accounted for.
