Ok - so steel barrels, 3 1/2" chambers - what chokes?

If you are going to use it for ball or slugs, knowing what the chokes are might effect the ball size you load.

Are you planning on using factory slugs or buckshot for deer & bear? If you are planning to use buckshot, I'm finished with this thread. I do not like the idea of shooting at either deer or black bear with shot - smaller than about .50 cal.loaded into your shotshells. A triple ball load using .490" balls will have 529gr. of lead (3x176.5gr.)just under 1 1/4 ounces. 4 balls will weigh 706gr. = 1.6ounces. A couple 16 bore balls might make a good load - 2 ounces.

If you are planning on using factory slugs - then buy a variety and test them for accuracy - one will usually be better than all the others.

If you want to use round ball and develop your own load data - even better - we can help with suggestions.

If you do not reload - you are stuck with factory ammo and how they shoot in your gun.

Generally the longer case fitting the chamber will give better accuracy, but not always.
