Got to call B*** S*** on you Michael

I was there when Giles Stocks was handing out free boxes (5rds) of TAP at Gunsite

Hornady's Tap Shotgun Ammo is the bomb in one of my Win. 1300 (10" at 30yds) with only the forcing cone extended 1.5" but it is very average in my 870 with the Vang voodoo, it really likes the Rem 8pellet low recoil stuff, once again showing that each weapon is a law onto it's self.
If you want to know what your shotguns capable of, do as Tex did. Buy as many brands/types as you can, go out and put them on paper at various yardage 10-15-25-30 pick the one that works the best and go buy a boat load of it.
The only down side (IMHO) to the low recoil stuff is possible under penetration. I've never shot anything over the size of a large dog (45lbs) with LR Rem stuff so if'n I was hunting larger game with it I'd keep a few round of some thing with a little more kick.
Low Recoil is great for personal defense training purposes, go out and get some, training that is, forget all the tactical/ninja crap to hang off your gun and get some training if you plan on using it (shotgun) for such, it's not the hammer of Thor, but it can be very close.
