Colt used the Colt Python barrel to make the New Frontier barrels. Actually, last summer I gave it to my grandson so don't have it anymore.
It's a Colt New Frontier P series from sometime in the 1960s. I own a Colt SA in 22 rimfire without the extra cylinder and it shoots point of aim and is very accurate for me. 2255 so it's the only thing I can think it might be. I had a hard time hitting tin cans on a log. Not even close.The only thing I can think it was is the fact that 22 magnum is slightly a different diameter than long rifle and the barrel had to be maximized for one. With the magnum cylinder in, both were very accurate but not so much with the long rifle. Rarely do I attempt to blame the gun for my failure to hit, but in these rate two cases, I can shoot better than the gun. Target model also available with 4 inches. 22 pathfinder can turn a few tin cans into an afternoon of fun.
It has the look, feel and weight of a higher-caliber revolver, allowing you to gain proficiency while using relatively inexpensive. In both cases, the Long Rifle cylinder was not accurate. Charters Pathfinder is a great introductory revolver for the novice shooter. I had a Colt 22LR / 22 WMR and a Ruger, also with that extra cylinder. I love single action revolvers myself, but I've been disappointed with the two convertibles I've owned.
