I am in central NY. I am a huge .410 fan and came across some really nice 97gr. sabots that I want to test out. I can use the .45/.410 barrel, but the slugs accuracy may suffer due to the slightly smaller diameter sabot vs. the .45 diameter barrel. The barrel is designed as a short-range survival and made for .410 shotshells, not necessarily slugs. It came with a "straight rifled" choke tube for use with thr .410 shot shells to keep the pattern SOMEWHAT decent. I have yet to pop a sabot through it, and no, I would not use the choke. I just want to see where the accuracy lies. I am looking for a .45lc barrel and also am considering a custom rifled .410 barrel. It is expensive, but so is are the sabots, and I am personally willing to bet that they (sabots) will take deer within 100 yards, given the advertised velocity. My shots are ALWAYS closer than 100 yards on game anyway. 50 yards is about right in my wooded area. for 'yotes we use .223 and light bullet .270 for those "waaay out there" ones!
