I have had a renewed attraction for the pumper. I have one now in all three calibers. All vintage. The 22 caliber with a Steve Corcoran custom stock is the most accurate and powerful pumper I’ve ever owned. I initially set it up with a Williams peep sight. Actually bought it with the sight already on it. My 68 year old eyes do quite well but I know I’m not getting everything out of it. Accuracy wise. I had this 3.25x8 power Nikon pistol/scout scope not doing anything so I mounted it on the ”machine.” My nickname for it. The loading port has easy access and the balance is perfect. I just finished sighting it in on this very windy day and I literally watched the pellet in air land on the spot of another one I was aiming for at 37 yards. I can’t wait for a beautiful calm day. I’ll post the results.
