Most do not like light or medium loads. Shoot heavy combat loads and you should not have problems.
You should also be able to shoot tactical buck and slug without problems.
Personally, I hate the politically correct tactical light loaded buck and slug. I LOVE the heavy magnum loads and sabot slugs!
My thought is if you are gonna use a shotgun, use a heavy load to get the most out of the weapon platform! Heavy loads never bothered me, flinching is not an issue, nor is the occational bruise.
I only begin to have limitations on round count when I fire my .450 Marlin, so hot shotgun loads are not an issue for me.
The tactical loads are very popular and don't beat you up as much... and should work in your auto.
