Yes I think thats the reason (LOWER RECOIL) that
I've heard,most people select the 20 ga
I own the 12 ga version, and most of my friends have purchased the 12 ga version, but from what I've read the 20 ga seems to be more popular
if you hand-load the lyman slugs seem to work rather well, if you select the loads that provide the higher velocitys,, loads that push the velocity up as they stabilize the 20 ga version best at the faster velocity levels in several of my friends experience

this does not seem to be an issue with the 12 ga version,keep in mind these slugs are loaded inside a plastic shot-cup,
that compresses and grips the slug, and rifling, in the shotguns bore,
(if its a rifled bore designed for slugs)
as its forced down the bore, the slug itself never touches the shotgun bores rifling , which acts as a sabot thats discarded as it leaves the bore.
you can buy a mold and cast your own at a considerable cost savings if you reload.

these work reasonably well in my rifled slug gun
This is load data for the 525 Gr. Lyman Sabot Slug. Its tough to format for the forum but the list reads of follows.
