Today I put a Nikon 4X on my ancient Brno bolt gun aft having used the rifle for a few months with iron sights. (I like the Nikon quite a bit but the Millet "Angle-Loc" rings are dogs. Don't waste your money!) I sighted in during a blizzard and was again astounded how well this 57 year old rifle shot.
Despite the blowing snow piling up against the Jeep, I stayed and practiced off hand as is my custom and again wondered how many other hunters have a practice regimine they follow and in this case, what they shoot. Mine is a Brno #2. I've had it for 29 years as of next September.~Muir
