I had the same experience as PJR. Target model gave me 2.5" 10-shot groups at 50 yds. from sandbags. I used a variety of ammo including Fed Gold Medal Target, Rem Target, Rem/Eley Target Rifle, Win Super X and CCI MiniMag. Not a decent group in the bunch. I've decided to run a brick or two of ammo through it to see if it will settle in. I mounted a Tasco Propoint 5 on it. It is an awesome looking piece. The mag release on mine is difficult to engage.
The T/C Classic is a beautiful rifle and much more accurate than the initial Buckmark results. 3/4" groups at 50 yds with the same ammo as above and I believe it can get better. Using the T/C Classic 2.5-7X28 rimfire scope.
