How does ML recoil compare to a 12 gauge sabot? I toyed with the idea of geting an ML to use in the shotgun zone, that way I can hunt during ML season to. I would probably stick with a max 250 grain sabot and 100 grains of pyrodex pellets. I am guessing a ML has better balance and trigger than a shotgun.
Bought a used TC Blackdiamond and though it's old and used it's a tack driver with 245 gr powerbelts and 100 gr pellets.
what kind of barrel are you using for you copper solids? It should be fully rifled and cantileavered for the scope. My 870 slug barrel I use winchester rifled slugs good out to 80 yds no problem. My 1100 w/fully rifled and cantileavered is good to go past 100 with 2 3/4copper solids though I prefer lightfields. Don't slap the trigger like your bird hunting and use a sling if you must shoot off hand. Better yet a rest. But practice makes perfect.
