1. Can I shoot 2 3/4 inch rifled slugs through it?

2. Which choke is best..?

3. If you have done this ,,what were your shot groups like?
Example ..with my Ithica 12 guage I'm getting a 3 inch group at 50 yds..

4 Will this effect my shotgun as my main purpose is for shooting turkeys?

Thanks for the relies,
C7
