I've owned 1/2 a dozen #1s ranging from .223 Rem. to 375 H&H and they all shot well to outstanding without any tinkering, just my handloads. My current #1 will do about an inch at 100 yards with 5 different bullet weights. Sometimes it's a tad more than an inch, sometimes it's a tad less. Every other #1 I've owned has done better if not half that group size at 100. A former Ruger #1 RSI was very finicky with almost everything, but eventually I found what it liked and it would shoot clover leaves at times. Unless you are a competition shooter, I would not let accuracy concerns sway your decision to buy a #1.
Not a Number One in this case but the 77 in the RSI configuration. It's a .308 Win. and I got it for the sum of $250 which included a decent scope, dies, shell holder, brass, bullets and a couple of boxes of factory ammo. I asked the guy why so cheap? he said it was the most inaccurate rifle he'd ever played with. He wasn't kidding.On a good day I might get a 4" group but most 5 to 6" was the norm. It took two years to find a load that was a consistent 1.5" day in and day out. Used that for a while and go the bright idea to relieve the fit on that metal muzzle cap. Groups now run a more consistent 1.25" which I consider an improvement. Funny thing is I ran into two mare 77 RSIs in .308; all ridiculously cheap because their owners couldn't make them shoot decent groups. I told them what I did but they couldn't be bothered so I bought them cheap. What worked on the first one worked with both of those as well. So far though they're a one load deal, a top load of W760 and the 165 gr. Speer Hot Core. Works in all three rifles. i haven't tried much with anything else mainly because nothing else worked in the fist one. Since I did the work on the muzzle cap though, I'm thinking of seeing whether or not other bullets might now work.
One of these days I might get lucky and find a #1 RSI to round off my collection. A 7x57 woulf be perfect.
