The 410 is acceptable for squirrels taken sitting, perhaps rabbits at close range, and for skeet. Oh,yes,adequate for HD.
For wingshooting,too many things can crawl off bleeding to suit me.In all these years of hunting, I've not met a good shotgunner who used a 410 on flying game.
I've hunted with folks who claim 410s're good for game at reasonable ranges. I just haven't seen it.
As for training newbies and kids, no. They need victories to build confidence, and it's hard to hit with the 410. Better choices would be 28 gauge and/or a lite loaded 20.
For an expert skeet or SC shooter looking for more challenge on clay targets, the 410 is a good choice.
Note to 410 lovers. There's been a revolution in recent years in the quality of ammo and guns. Long forcing cones, overbores, better wads and harder shot give patterns the gunners of old would die for.
Nobody to my knowledge has bothered to upgrade the 410s performance with a long cone,overbore, harder shot,beter wads,etc. Anyone want to hazard a guess as to why the shotgun round that needs upgrades the most has been left in the dust?
My SWEG, because not enough is not enough.
