Had a chance to shoot an older Marlin 94 357 with micro groove rifling. I was all ready to be embarrassed by missing the 4" steel spinner I was aiming at. After all, I've read nothing but bad things about these guns on the internet. Horrible accuracy, can't properly stabilize bullets and such. I didn't find this to be true at all. If there is a difference in accuracy compared to other open sighted lever guns, it sure isn't much. After this experience, I'm not put off one bit by micro groove barrels. I don't see anything wrong with these guns.
