Re: WTB: Browning A-Bolt rifled shotgun
You will find the issue will NOT be the gun!
You simply have to find which slug your gun likes, and they all have definite likes and dislikes.
Brenneke is really touting their new slugs to work in about all guns.
I have used one slug in one gun and got 1.5" three shot groups and the next gun gave me 12" patterns with the same slug.
The ones I have normally had best luck with are the (for rifled barrels) Fed Prem Barnes Expanders, Hornady, and Win Premium Platinum.
The Brennekes will often work in a rifled barrel also.
By the way, the Nikon Shotgun scope with the BDC reticle really works well. Just have to confirm the circle zeros out to either 200 or 250.
