Sighting my Remington .44 was a project put off for years as I thought "Big deal, no power, no accuracy." Boy was I WRONG!
First I placed a little math and machine shop trig to sight that puppy to regulate it to 25 yards. My new front sight height calculated I drove the original sight out of the dove tail and removed the post from the base. Turned a small pin down to have a step on the end then silver soldered it to the base. Leaving just a hair high to fine tune after installation. Shaped it slightly to match the original and reinstalled. Like George, I opened the rear groove out just a bit to get a bit more air gap. Made a measure spout for 28gr triple F and WOW. What a shooter with .451 dia soft lead balls. Soft recoil and very accurate and as I did once you can jack them up to what seems to be magnum power, at least by noise and recoil. But all the power in the world does you no good if you do not hit what you are shooting at!
Always wanted a Colt .44, but no more. The Remington sighting system is so far superior. One certainly enjoys them more when you can hit what you are shooting at. My pistol was a Christmas gift from my wife for our first Christmas together. Yeh, still have the wife too!
