    Been a lurker for a little while. First time poster / thread starter. My question is about a .22 my father used to own. It needs a little refinishing and rust removal. I've seen a very helpful thread on this within the forum. My new question is about ammunition. I've seen somewhere that I shouldn't put newer, hotter rounds through an old rifle. True? If so, what grain do I use for a .22 made in the 60's? I certainly don't want to ruin my dad's old gun, especially when its perfect ( weight / length ) for my daughters to begin with.
    Also, does anyone here know how, or even if, I get the action to stay open? My grandfather's .22 was a model 60 ( a newer one he bought to keep pace with the kids ) and it stays open and shuts with the push of a button directly under the action. the 99 M1 just snaps shut. Is there a trick to this, or is this normal for the model? Sure would help to clean if I could get the action to naturally stay open.
    Any cleaning hints or alerts I should be aware of? The fewer surprises, the better.
    Thanks in advance!

    Any 22 Long Rifle ammo will be fine.

    There is no bolt hold open. At least if there is I never figured out how to work it on the one I used to have.

    The bolt hold open was added to the Marlin .22 action in the late 80's. And it's fine with any .22 LR ammo.
