Is the main difference the shorter barrel???
Ditto...I've never owned another rifle that shot as bad as the TDS I once had. Kind of soured me on all Marlin lever 22 rifles. Traded it for a marlin model 60 that shot like a laser.I had a TDS once for a month or so. It was the worse shooting 22 I ever had. So I sold it. I wish I kept it and had it to sell now!
