Deer stalking: A friend has treated his rifle with some high-tech aftermarket product that is supposed to reduce fouling and increase both accuracy and velocity. He can’t honestly notice much difference but are you aware of any of these products that really do work?
I have been left an old side-by-side which was part of a collection and has not been shot for many years. A gunsmith tells me it has only black powder proof. However, I am assured it is safe to shoot. Where can I get 12-bore black powder cartridges?
