I recently went out to spend several days at a "Guest Ranch" to ride and rope and feed cattle. I took with me a Valmet .12ga O/U for the ranch skeet range. Since this is WAY up in the boonies I took some 00 buck rounds and some 1oz slugs. Saw two black bear on the horse trail while out and about. Looking later at the O/U it does not look like the barrels have chokes nor are there any indications of being able to install chokes on this gun. Seem OK to shoot slugs out of this type of gun without damage? I bow to your greater knowledge.
