Re: Least accurate gun
Two Ruger .44-40 Vaqueros, hands down no comparison. Wouldn't stay on an 8.5x11" sheet of paper at 25 yards out of a Ransom Rest. Turns out that Ruger did something sensible in barreling these guns, using the .429" barrels that have long since become standard for the 44 Special, 44 Mag, etc., instead of the .425"-.427" barrels originally found in the .44-40s. Problem is, they didn't modify the chamber mouths; they left them at .425". So, you have a .429" diameter bullet, swaging down into a .425" chamber mouth, and then rattling down a .429" barrel. When I checked the dimensions and found this, I called Ruger about the problem and suggested they change the chamber mouths to match the barrels. Got told repeatedly by their reps that "it was within specs." Yeah, I know, but the specs need to be changed. "I'm sorry, but they're within spec."
Bill Atkinson of their AZ plant was kind enough to ream the chamber mouths out to bullet diameter, and they shot fine after that. Ironically enough, when I told him what was going on, he just shook his head and said "I told them that, over and over."
Sold them not too long after that, and have never bought a Ruger since.
