I bought a pile at $10 a brick.
Lowly ammo but it works fine in the Marlin 60 and the Ruger MkII.
No go in the Ruger 10/22 takedown.
BTW The Bolt lock in the Ruger 10/22 sucks.
That needs modification.
Very iffy in my K22 Outdoorsman (1930), a modern 617, a Model 18, and M41. Maybe it’s a Smith thing?
