I went the SBE II direction 2 years ago and couldnt get slugs to shoot very well out of it with the slug barrel. THis past week I shot some slugs out of the M4 and was very impressed with the accuracy.
Saturday morning was opening day of deer season here in Indiana. I saw 11 deer in 3 hours. THis was the first large doe that came buy. 60 yards, one shot. Deer went down like a fat girl on prom night.
