I've got a 28 in accuchoke barrel for my mossberg 500. I've tried several different kinds of shells, and it seems to me that 2 3/4in short brass shells hold the tightest pattern out of them. What kind of shotshells work best in yours?
Not knowing what your planned usage's are, I'll give you a general overview of what mine likes. For clay targets Rem. STS, and Fed Gold Medals. For Pheasant Fiochi Golden Pheasant loads, 2 3/4" 1 3/8's oz nickle plated 5's, these are the absolute best killers I've ever used. Called coyotes, and Fox handloaded #4 buckshot. Waterfowl, Rem. Hevi-shot, sized to the intended birds. Home defence 1 1/2 oz lead # 2 shot (only one wall between my bedroom door and the Tahoe). 2's give enough penitration in the badguy at in the house ranges without going thru the walls.
What works in a Browning 28" is different than what works in a Mossberg 28". My understanding is that there are four components to a shotgun bore; forcing cones, bore, choke bore and choke. They all are components in what works in your gun. There was a great alticle in American Rifleman about shotgun bores in (I believe) November 2004. You can also check out Mossberg's website for info. (Probably no help there.)
Your best bet is to go to the range with a box of each. I've patterned my Browing a bunch of times to find the best Trap load for it...
Good luck and check back in with whatever you find.
Do you have a extra full turkey choke tube for it? If not you will want one for turkey hunting. Also this time of year most sporting goods stores or gunshops will have turkey ammo displayed, If they don't, they should be able to help you find some. I will be using a 3" #6 shot 1 1/2 ounce Remington HEVI·SHOT High-Velocity Magnum Turkey Loads
It's a Mossberg 500a with a 26" accuchoke barrel, it has the screw in choke. Which work best for these, because I know someone has the same. What makes the extra full better than the full. The pattern charts show extra full to be similar to modified.
