The savage is more known for their accuracy with their bolt action 22's. I cant say to much about the remington because i havent shot one, but you dont hear to many good or bad things so i take it their in the middle.

If you want to customize your gun in the future than definitely get the ruger 10-22.

If you have to have a semi auto than the marlin model 60 really is the best choice.
the mossberg 702 plinkster is also a nice plinker gun, just dont expect the accuracy to be great.
