Over and over again,
It does not matter what the ounce and a half load is; bird, buck or slug but the powder charge used to propel it...They all will recoil the same...
Goes back to the old question, what is heavier (not denser, not smaller or larger in size) a pound of steel or a pound of feathers and how much energy/force is required to initiate movement in that weight and to make it go the necessary distance!
Check your charts and find what the velocity and energy is for your intended defensive load and then find a cheaper product producing the same levels--that is only for recoil training, conditioning--
OF COURSE the effect on the target will be different but at typical HD ranges (<15 yds) spread really isn't a factor but penetration is...#12 will pepper them, #4 will hurt them, #BB will really hurt them--dead, #4 buck will kill them really dead and the bigger buck are just bigger pellets but far less in number and with slugs, you'll probably miss...If you're shooting slugs you might as well shoot a rifle or pistol...
Practice with the cheap shells then use the HD load for a couple of shots to see the pattern (spread)...Remember that
the longest shot you're going to take--is in your house so measure what that is and practice that range--and of course closer like from your bed to the end of the hallway and to the end of your room...

As you can see the differences are slight, could be the amount of powder, size of wad, with or without a shot cup, size of shot cup, between the two different reports...
At ten yards it's like tossing a softball or basketball down the hallway...
It's 1" to 1 yard on FULL choke not cylinder...
And it don't matter whether you use buck or bird the expansion
will be about the same...Yes, buck will spread more but an insignificant amount at 10 yards
When the spread becomes to open it will allow a clay target or a live bird to fly through unscathed...
