There's one available to me out where I shoot, but it messes me up really badly with irons. My POI with it vs without it are nowhere near each other. If I sight a gun in off the sled, I'd be lucky to hit a buffalo broadside at 50 yards without it.
Aside from the necessary evil of shotgun slugs, I've just dumped all my heavy recoilers and replaced them with milder cartridged rifles. We can use muzzleloaders for the 2nd half of our firearms season, so I always pack my .50 when I can. It's much more pleasant to both carry and shoot than the shotgun.
