I have a 2-7x on my .30-30, love the levergun/scope combo!
I much prefer a scope to a red dot, least on a rifle.
2x is still very low and great for a brush gun, get a 1-4x or 1.5-5x if you really want low magnification and a scope perhaps...
a red dot past 50yds IMO is pretty bad...
I've had 2 red dots on 2 diff guns before and have sold both and gone with scopes in their place...
