I rarely comment here, but this time I will.
I have had both and I recommend the Ruger.
The frontier I had was sometime after the 6 inch barrel
came out and Colt had made them with .224 barrel rifling.
That is oversize for the 22 rimfire. I know, thats the 22
mag bore size, but the 22 rimfire shot lousy.
The only one I found that shot well in it was the 22 Yellow
jacket, of all things, but was exceptional. This was
probably due to the higher pressure to fit the bore better.
My Ruger 3 screw has done very well with many brands.
I think you will do better, overall, with the Ruger.
I really liked the Colt, but sold it.
