I'm new to the group and have a Danishicon return that was rebarreled with a VAR. Its a tack driver. I got a deer with it 2 years ago with one round Federal 165gr. Got to use soft nose here in FL. I since got a little education about gas cyl plugs. I'm looking for some more hand holding on this subj. How would you set an adjustable plug? Are those with multiple ports better? What am I looking for here?
