I too am not too recoil sensitive.
When I lived in California, I would bird hunt in one area that had quite a few deer. I decided to try my luck there. The one drawback was that it was a shotgun only area. I looked at slug barrels for my shotgun, then I spotted an H&R slug gun. It was not only rifled, it cost less than an extra barrel.
I purchased boxes of several different slugs to do accuracy testing. I decided to leave it with iron sights since the area I was going to use it in was brushy. I went to the range and set up a target at fifty yards. I was going to start by shooting three rounds of the different projectiles.
The first trigger pull was brutal. A five and a half pound shotgun, firing slugs, from a bench, kicks hard. I owned a rifle in 338 Winchester Magnum at that time. It was a plinkers delight compared to the slug gun.
