I have a Winchester 94 in 44 Magnum that is shooting extremely (2-3 ft) low. My uncle bought this rifle new in 1977 and never fired it. I go it from him 5 years ago unfired in the original box. The gun shot okay with the buckhorn sight. I had to put a spacer under the ramp to elevate it beyond maximum to get it to shoot to point of aim at 100 yards, but once I did, it shot small groups. I recently replaced the rear buckhorn sight with a Williams Foolproof aperture sight. Once I did that, it shot low. I eventually filed the front sight down to a nub, primarily trying to get the stupid ball/bead off the front post. A gunsmith recently gave me this plastic front sight and installed it on the gun. I was supposed to go shoot the rifle and clip off the upper parts of the plastic post until I got the right height at which the gun would zero, and then the gunsmith would install the right height front sight. I never got there. I fired 100 rounds 240 grain SWC "Cowboy" loads (from HSM) through it and all but the last 10-15 rounds missed the 2 ft square target frame entirely at only 50 yards. It took a lot of guesswork, but what I've confirmed is that the gun is currently shooting about 12" low and 12-14" to the left. I have the rear sight aperture cranked way up high and hard to the right. That little plastic front sight is cut way down, almost to a nub again. I'm using the top, right corner of the target frame as a point of aim, but I'm hitting in the left and bottom half of the target frame. It's also absolutely horrible shot groups-all over the bottom of the target frame. What gives?
