When I shoot a 12 ga.. gun I expect some recoil. I shoot worse when I don't have it. When it's so easy to load what you need, for any gauge, I just do not see the attraction of shooting inserts. Maybe the day will come when I want a shotgun with "non-existent" recoil, but I'm a long ways from that, now. Prolly why I've never bought a set of gauge reducing inserts.
I can see a perceived advantage to having a carrier barrel set for sub-gauge tubes, but I did pretty decent in NSCA sub-gauge sporting using separate, dedicated guns in each gauge....... 20, 28 and .410. Shoot a practice round of five stand with each gauge gun before the registered event and muscle memory took over from there.
