I have a Marlin .22 Glenfield Model 60. I'm just starting to use the rifle at the range and I'm just starting to learn about different ammo. My question is can I use .22 MWR TMJ High Velocity ammo in this rifle. The last time I fired the rifle I was using High Velocity LR ammo (which worked great) and this time I bought a different kind by accident (which is longer). If I need to take it back that's fine it's just that I'm going to the range tomorrow morning. If you can add any info on different .22 ammo out there I would much appreciate it. Thanks!
