The .30-30 was primarily used in the Midwest, Northeast, and Southeast. The most popular deer rifle out west, and in the Southwest, was the .270 (at least it was way back when, when I lived in California).
.270, 7mm and .300mag are the bulk of rifles out here for those who think they can shoot over 200 yards.
Even if they can’t.
I prefer the general purpose .06 for almost all applications.
