RE: Slug Gun Recoil
Brownell's has recoil pads, recoil supressors which can take the place of the plug or go in the buttstock. Some are weights, some tubes of mercury, some I think may be hydraulic. Another item I found that helps the shooting and with the recoil is a stick on cheek pad for the top of the stock. Another way to add weight is use a stock sleeve that holds 5 slugs and a sling that holds four or 5.
Take advantage of the rifled barrel for range and accuracy. My old 1100 and old hastings barrel put 5 Hornady H2ks inside a 3 inch circle at 200 yds. Although I took a doe at 170 yds. with a Federal Hydrashock, it took about 12 inches of hold over. I've also had the hourglass sabots break at the waist and slide up along the shoulderblade rather than going thru it.
