DRC458 and myself took down about 50 cedar trees using #2 lead shotshells by pushing them over with the foot and shooting them off at the ground on one of my places.Nope ya don't a need dot, the ghost ring sight on mine proves sufficient for it's use.. Couple that with 00 buck 9 pellets the size of a pea and it sure makes a mess out of a milk jug.. It also brings a smile taking down small cedar trees..
Eastern red cedar is one of the few trees that won't regrow from a stump if shot off or cut off below the lowest limb.
