From what I understand I can shot rifled slugs from my cylinder bore (Mossberg). My question is what can I expect in terms of accurracy from an 18 inch barrel (if any).
My 870 HD has proven accurate out to 25yds so far with a cylinder bore barrel and bead site. In using both Remington Sluggers and Federal rifled slugs I was able to achieve one hole groups that resembled a 4 leaf clover. Will be trying it on the 50 yd range next.
