Tomme: "The limiting factor is my eyes not being able to see the front sight."
"Progressive Lenses" and Fiber Optic Sights is the fix.
The stock Front Sights on both these barrels are stock Browning Sights and are barely visible. They are getting replaced with FO sights today. See Pics,,, In any kind of Daylight you can't miss these. I use this type of sight on most of my pistols and shotguns.
I have about 3-4 different factory slugs on hand. Mostly different Federals, Tactical LE, Low Recoil, 2 3/4" Maximums at 1610 fps. Will try others. I really want to try some of those Lightfield Slugs and some Brenneke's thru the smooth barrel.
I've got some BPI DGS Slugs that I got from the Italian makers before BPI had them. I only have 5 of them but they will serve to decide if I need to buy more. Probably not as I have the Lyman Sabot Slugs and will probably get a Lyman Foster mould too. Plenty of stuff to shoot thru that gun.
The Federal LE are what I shot at Front Sight last month, and they worked OK out of my M 500 with the Vang Comped barrel. Over there we shoot slugs at 35 and 50 yards on steel and paper targets so I don't need super duper accuracy from those. Still right at 2-2.5" at 50 yards is better than most get.
The Lymans will go thru both barrels but am looking at the Hastings Barrel for the "rifle like" accuracy,,, If it exists?
BB: what kind of accuracy do you get out of your Hastings Barrel with FB Slugs? 650 gr should put a pretty serious hole in stuff!
