I recently converted my 21" modified rem-choked 870 to an 18.5", 7 round combat shotgun.
My new barrel has green tritium lamps in rifled sights and a fixed modified choke. I picked up 50 rounds of military 00 buckshot to pattern this barrel with, but have not had a chance yet.
Since I haven't patterned my barrel I'm loading up with the Winchester PDX1. I think it's a great concept, from point-blank to a couple yards or so it should leave one big ragged hole. From a few yards out to 30 yards and beyond I should be pretty accurate with the slug. If not, then the 3 buckshot pellets should help.
I was just wondering what others might think about the PDX1 12 gauge round. I'm excited to shoot it!
