Slightly misread the title so much better than the one I thought it was gonna be. One of my early guns was a Marlin 989M2. Not bad for the look and feel (not as good a replica as yours but not bad) so good to sit with while watching WW2 or Korea movies, perfectly accurate, and often would fire TWO ROUNDS IN A ROW! Semi auto-splendor! Okay, sometimes it did 4 or 5. But so rarely it was a surprise.
Yeah, tried a lot of ammo, a lot of mags. It was one of the good old days gun show uses: get rid of the awful and gamble on something else.
I am /pretty sure/ I got another .22 with it, so that's how I came to acquire my Fieldmaster (Remington 572), which is a tedious tube loader but scrupulously reliable, and the most accurate .22 I've ever seen much less fired. Back in college there was an indoor range used by a tiny club of mostly old men with custom Martini-action .22s and bags galore. Once I was shooting the Fieldmaster and doing well, so one of these target guys had me set the gun in his bags, with my $29.99 scope and all, and I got ragged holes, visibly better than theirs, at any range.
