This is my kinda topic!!!! Yes a .410 will bust one with TSS. I would highly suggest the Stevens 301 single shot if I was planning on using it forever....however I would get the 20 ga over the 410. The 20 ga gives you so much more everything(pellets, range, power). I bought the Benelli M2 20 ga 8 years ago and wacked my Mississippi limit with it every year. I've got an old 870 410 for my son but really don't trust it much past 25-30...just not a good enough pattern without the choke. With that being said just as soon as he can handle the extra length of my M2, Im gonna start toting a Franchi Affinity 3 20 ga. I've got the Affinity lined out with the Sumtoy .562 and the M2 with Indian Creek .555. Dang Im ready to bust a bird in the head now!
