Found a Marlin JM 1894 in 44 mag made in 1977 it comes with micro rifling . Is that bad for 44 magnum shooting jacketed bullets ? I hand load so I can shoot cast bullets . Also is $460 bucks a good price for a used rifle that been kept in good shape.

Condition ? $460 is very good price

Was it rode hard ? Put away wet ?

This '77 will have the old style ejector.....

Always good to have a spare.......Numrich has 'em......$34

Compared to the newer style.....which are only $14

$460 is a very good price if it's in good condition.

What year did they change from old style ejector?

A really good price, if really clean. The micro groove rifling will shoot jacketed bullets just fine, and if sized right, will shoot cast bullets really well.

1980 ish......quickest visual inspection.......left side receiver.....

new style will have a hole for ejector to rest in.....as in GB pic here

I have an 1894 357, made in 1980. It has the micro grove rifling. Mine shoots a gas checked lead bullet excellent. Most of what I read said lead and micro grove rifling was a no go. I would go for it.
