Just killed two deer with my 870 one at 110 yards using Brenneke 3" super mag. 1 3/8 oz. I won't use anything else !!boomstick said:I was looking at trying out some of the Brenneke slugs in My new 870 12 GA. with a 20in. fully rifled barrel. Has anyone tried them in their 870? and what kind of results did you get at 50, and 100 yds.?
