I had to hunt with slugs here in Ohio for years and shot slug
turkey shoots every weekend. Have owned about every US made
slug gun that was on the market. Have made slug guns out of
countless older model guns. I shot different slugs in different
guns. Like rifles some did better with a certain brand. We sight in
at 100yds. Any gun that won't do 3" after trying Rem, Win, Fed
and Brenneke, was offed or different barrel was tried. My 870
liked Brenneke slugs. We did find out that if you go through your
slugs and cull out the ones that rattled in the hull, you will have
less flyers. I had a few rifled slug guns and rifled barrel for 870
and Moss. I never got into them and $3 slugs. My smooth bores
were doing a good job on deer at woods ranges and I won more
than my share of shoots against rifled guns. I will say that beyond 100yds the rifled barrels are better. I have seen some
amazing groups shot with rifled barrels and sabot slugs. Some
guns or barrels will not shoot slugs worth a darn. It has nothing
to do with choke. The foster slugs are made to shot through any
choke. When deer hunting first started in Ohio it was only 2 or
3 day season. Slug guns weren't new but most guys used the
shotguns they hunted small game with. Most everyone had FC
guns. There weren't many that wouldn't hit a 3lb coffee can at
40yds.over the bead. I would much rather hunt with a rifle
myself but there is a lot of myths about slugs passed around by
guys who have never used them.
