Based on gun books I read as a kid, I always wanted a "K-22 Masterpiece" for it's accuracy. I briefly owned a 6" 617 almost 20 years ago and after testing it off a bench rest at 25 yards with a scope and a dozen different types of ammo, was really disappointed in it's accuracy, plus the gun was heavy.
In 2014, I bought a MKIII 22/25 Lite and did a few mods to it like the Slingshot conversion, removal of the LCI, Volquartson trigger & sear. Never formally sat down and tested it, but while it was absolutely a blast to shoot, I got mediocre groups shooting offhand. But then I wasn't expecting much out of it.
Here lately I had been toying with the idea of buying another 617 in 4" or a 17 "Classic" and mounting a scope on it to see if I could get good results accuracy-wise. A few months back, I came across a deal on a Weaver pistol scope and bought it. I also got my first suppressor in late spring of this year and decided to put the two together on my 22/45 Lite just to try it out off a rest. I just grabbed the first box of ammo nearby and got this...
Kind of negated the "need" to buy a 17/617 for accuracy. In my online research of 17/617's for group size, almost everyone says something like, "shoots better than I can hold", but they never tell you what that number is; and of the very few examples I saw of actual group size, most weren't even in the running compared to that one from my 22/45 Lite. (That being said, I just bought a 4" 617 and a 3" 63 in the last two months, but not because I hope to beat the 22/45 for accuracy.)
