P9shooter; Hang on to that Mossberg. These older rimfires are one of the true "sleepers" out there. Many were not aesthetically pleasing, but most shoot very well indeed! I have a mini-collection of older Mossberg 22 rimfires and I have silenced many a range egotist with them over the years. 144's are one of the best, with 146b's, 42's & 142's, 44's and several others right in there. I have a 146b that will stay around 1" at 100 yards with ammo it likes.
I also have a couple of Mossberg's tube [in the rear stock] fed, semi automatic 22's. These are amazing 22's, which I would put up against any production, and most tweaked, 10-22's. They are practically flawless feeders, and will digest almost anything. Every once in a while, you will find one with nicely figured walnut, which is simply a bonus. While they do not demand big money, they are going up, and I thinks they are a definite keeper. Regards, Eagleye.
