Sage advice from Guntech, as usual.
IMHO, for what it's worth, after 40 years of shooting literally tons of lead, and experiance with steel over the past dozen or so years :
Stick with LEAD ONLY [for Turkey hunting] with that Briley Extra Full ...
( Kent Tungsten Matrix & Bismuth are also O.K.) but Products like Remington's old "Hevi Shot" and newer "Wingmaster HD" and similar non-toxics from Winchester and Federal are all iron/steel based composites and are still much harder than lead pellets ... they generally do not respond to tight chokes in the same manner that lead does.
If you want to shoot steel [for waterfowl] get yourself a couple of original equipment Remington Skeet and Imp. Cylinder chokes, ( I assume you already have the Modified that came with the gun) ... and pattern them all at a MEASURED 40 yards, with the shells you will actually hunt with, to determine which provides the most even, well-distributed patternS.
Large steel shot often works best with Skeet or Imp. Cylinder, smaller stuff like 2's & 4's, generally with Imp. Cylinder or Modified.
For those of us who grew up with lead, most found, usually by trial and error, that their wingshooting actually improved when using Modified or Imp.Cylinder chokes. Far more game is taken with a shotgun at UNDER 30 YARDS than over. It takes a very skilled and experianced wingshooter to effectively use full choke, with lead, to take game consistantly at 4o yards and beyond where full choke patterns are best utilized.
More is not always better !
Tough lessons ... but good advice is often very hard to come by at the
"Big Box" stores.
