A 10 guage can't do a whole lot more than a 12 guage, in my opinion. If you are really hurtin for more shot in each load, just use 3.5" shells. If you arewanting more long range performance, I would look into a tighter choke and better-performing long range shells such asBlack Cloud and maybe aPatternmaster chole tube. But really there is no more practical and versatile shotgun than the 12 guage. Also, you will also find that ammo for the 10 is more expensive and not as available as for a 12. I'm sure there will be different opinions, so good luck in whatever you choose.
