If you would use a standard lead turkey load for a 12 gauge on a turkey at 25 yards, but wouldn't use a TSS 18 load out of a .410 at the same range, it doesn't really make sense. 11/13 oz of #9 TSS 18 has around 305 pellets, and carries energy/penetrates as good or better than #6 lead, and can be loaded around 1100 fps from a .410. A 2 oz load of #6 from a 12 gauge would be about the same speed, and would have around 440 pellets, so a little over a third again more, but if you have any experience with TSS 18, you know that it generally patterns better than lead, and has a plenty dense enough pattern out to a long ways with the right choke. Not trying to argue at all, just am unsure if you are aware of the specific qualities of TSS 18 that actually turns a .410 into a viable turkey gun. If we're just talking lead, then I woukd mostly agree with you.Can it be done? Sure. Should it be done? Probably not. I LOVE my small bores for dove and quail, and I have patterned them for turkey loads. I will not shoot at a turkey past 11 yards with a .410, regardless of what shell I use, just not ethical. Yes I know I just opened the flood gates of criticism. If you have one that will make the shot and you have patterned and know your max range, I support your decision to hunt with it. I will not and I did not say it should be illegal, I just said I will not try it, so no need to argue with me over it. With my bow, I can kill a turkey out to 45 yards. Because of being ethical to the turkey, my buddy and I will not allow anything less than 20 gauge in the turkey woods, or a bow.
