16 gauge & deer/turkey hunting question

[skeet]

I have to assume you have screw off chokes on the end of the bbl. Don't think I've ever seen removeable bbls on a bolt gun. They did make the guns with removeable chokes that screwed on the end of the bbls. If that is what you mean..use an open choke for slugs...and yes you can shoot bird shot and slugs from the same choke. But remember that slugs generally shoot better from Improved cylinder or modiified chokes
