Many have used various handloads and factory loads
in NEF with scopes and they get 2-4" groups at 100yds.
Usually I get 2-3' at 50 yds with peep sights and bad
eyes with Savage and NEF.There are slugs from light to
heavy you can use, even some saboted, that get real
good speed with our loads. One gun we set up was a 1887
Win 12ga levergun replica with long heavy barrel. I got one
oz Brenekke up to 2700 in it.Here's pic.Ed
