I hunt California chamise, manzanita, buckbrush and heavy timber with a 20" 308 win. Very rarely are shots over 400 yds. For oak brush, sage mix and quakie patches I like a 22" 270 and for open plains of Wyoming or rolling sage hills of Colorado I take the 26" rifles in 25-06, 280 AI or 300 win mag depending on the animals I'm after. I'm not a one gun guy by any means. So the average has me in the 23" slot.
