I like Marlins. The 1894 C in 38/357 is a great shooter. Ammo is cheap, it accurate, it shoots the same ammo as your revolvers.
44s and 45s are good too, but for plinking and small game the they cost a bit more to shoot.
However, it depends on what you shoot. If you are a deer (or simular game) hunter I"d recommend the old stand by 30-30.
Don't sell these little rifles short. We all have seen Midway's Wednesday Night at the Range--- Impossible Shoots.
I'm one of those guys you don't tell "don't try this at home", thats a sure way to get me to try it.
So I've been practicing shooting the edge of playing cards with my Little Marlin in 38 SWC. At seven yards I've gotten where I can cut the card one out of three times. A bit more practice and I'll move to 15 yards. Its fun, it cheek, and it keeps me out of bars and of golf courses. These little lever actions will do it.
