I have had several 63's in 6 shot 4" and only 1 shot very well and I sold it to a friend of my sons. My 617's and 17's all shoot better.
I had a 18 that you could not hit a 12X12" box with at 25 yards. I tried everything to no avail. I got fed up with it and took it to a gun show and sold it to a dealer. I told him the problem I was having with it and he told me that I just wasn't a good shot. I smiled and sold him the gun. At the next gun show I went up to him and asked him how the gun shot. He said that was the biggest piece of junk he ever shot. At least I know it wasn't me!
I really would like to have a nice shooting 18 someday.
All I ever had in the Ruger flavor is single sixes. They shoot OK but I am not impressed with them. I would like to try thier new SP101 though at some point.
