You are correct with your assumption. Give it a try and share the range report. )I've got an older (1972) Marlin Glenfield 60 but have never shot anything other than standard velocity .22 ammo in it. Do any of you shoot the CCI mini-mags? I assume that the action can handle the CCI mini-mag ammo ok...
I shoot everything except hyper-velocity thru my mod. 60. It likes them all. Hypers will damage the recoil buffer over time. However, the mod. 60 is the only 22 rifle that I have right now and I have 1200 rounds of CCI Stingers stashed just in case. If the SHTF, I will certainly break it out of storage if needed.
