Gentlemen,
My Baikal comes with an adjusting wheel for regulation, so it is fairly easy to adjust for whatever weight bullets I choose. As for my choice of a 220 gr instead of a 180 gr, I am a big fan of using the heavest bullets whenever possible (within reason). Most of my hunting is in thick cover and at close range here in the South (God's country) therefore the iron sights at 50 yds. Some times a chance at longer ranges in Texas therefore the 100 yd sighting-in with the scope.
I stand a much better chance of a through-and-through shot on hogs with a 220 gr than a 180 gr slug. Therefore a better chance for a blood trail if the beasty doesn't go down instantly.
