Not specific to a Marlin, but in general, I have found the Remington Premier .22 Mag ammo to be the most consistent. However, the last .22 mag that I shot liked the Win Super X hollowpoints. It didn't like the Super X solids though. I haven't tried the Hornady V Max .22 Mag, but their .17 HMR is good ammo. I haven't had any luck with Fed or CCI .22 Mag, but all my ammo was several years old. I think that the new ammo could be better.
Bottom line, you'll have to try different ammo to see what your rifle likes best. Unfortunately, that usually means having to buy a box of each, knowing that 3 or 4 brands probably won't work, and if you're lucky, 1 or 2 of them might. At $12 - $14 a box, it's an expensive experiment.
Good Luck, Tom
