De-coning an acre of front yard filled with Ponderosa pine and Douglas fir trees with wicked senses of humor used to be a 5 to 7 day task. I just cleared almost a quarter acre in less than 2 hours (3 x 35 gallon bags full of cones so far).
I own several rollers and this model is the absolute best for picking up 9mm brass. This is the second model of this roller I have purchased. I shoot competiton and pick up brass at my gun club. This size is the absolute best for brass.
