RE: Sons first elk hunt
Howas and Vanguards are the same action, made at the same plant. The difference is, I don't think Howa promises their rifles with the accuracy standard WBY does. Plus, IMHO, the Howas look cheap.
Depending on the age and size of your son, a 300 Win might be a touch big to start with. The .30-06 is just right, and with the reduced recoil factory ammo available for practice, he should be a regular dead eye come season.
