So I think I have my decision for a cantilevered deer slug barrel for my 12ga 870 narrowed down to a Hastings or the factory Remington one. My question to you all is have you had experience with either barrels? Does the Hastings hold better groupings and is more accurate? I am kind of a stickler for accuracy even though slug guns are not the most accurate. I don't want to pay more for the Hastings if it is not anymore consistent/accurate than the factory Remington one. If you can provide measurements of groupings you have had that would be great.
