I gather you are interested in an In-line type of ML, one that will accept a scope of some sort?

Don't overlook a quality production sidelock percussion in 50 or 54 caliberas your first ML. I would wager that a sidelock is a bit more versatile and less expensive.for hunting, small game, targeting and plinking when shooting strictly patch and roundball.

For sidelock percussions:
Thompson/Center Hawken & Renegade, Lyman Trade and GPR rifles are really nice

I have many more sidelocks than I do in-lines and I shoot and hunt with sidelocks about 90+% of the time.

Back to inlines, which is what I think you are interested in.

Camo is not needed unless it really makes you feel better, the game will not object if you go with simple bluing, nickel or stainless.

For a first ML, not knowing what you budget is I would suggest one of the break action or drop action types in 50 caliberthat are among the easier to maintain.

Break actions include: Thompson/Center Encore, Knight Vision, Traditions Pursuit Pro (not the LT) and CVA Optima Pro. There are others as well.

Drop actions include: Thompson Center Omega, Knight Revolution, CVA Kodiak.

Take a look at some of the used ML's. You can sometimes find some really nice one's if you scrounge frequently.

I recently purchased my second T/C Omega for$200 in mint condition from a fella out of work. Stainless steel with Laminated Thumbhole stock (Retails for over $550). Going to top it with a Leupold VX-III 2.5x8, Leupold QR base and QR High Rings.

Best of luck!
