I fell deep into this rabbit hole and am stuck.
I bought an Encore frame off Gunbroker, an SSK stainless 410, 3" chambered smoothbore barrel with a .380 choke tube, it's16+ inch. I got Keystone grey grips. I installed a Holosun green reflex, and I'll carry it in a Shamrock brown leather shoulder holster when it arrives next week. I got a box of 2 3/4" B&P #9 plain lead shot for practice and 3" Federal Premium TSS18, #9 for turkeys. Its patterns on a turkey head target show I'll kill any within 30 yds, but beyond that is doubtful. My Wisconsin turkey season opens May 8.
This project cost a truckload of dollars. MGM barrels are less expensive, but they don't make a 410 specific barrel and I didn't find anyone else that does, and there were none on Gunbroker when I was in the buying mood. I think there is one now. I actually like the looks of the original TC 14" ribbed barrel better. Some folks show they're getting 40 yd killing patterns with TSS, but I don't see how with a short barrel. As usual, ammo at the local Scheels is limited. I couldn't get a 3" lead load for comparison to the 3"TSS.
