I did some measuring today by using a hornady great plains bullet which has a very thick band at the nose and after pushing it down the bore, I used a ball screw to get it back out.
Bore measures .499" lands and .503" grooves. Tight bored some would call it, but she takes a .020" nicely and shoots that load very well.
