Ray, Yea man I'm using 3" hevi 13 blends. I've hunted with my 1300 NWTF short turkey, x-long x-full win. choke for about nine years now. It's got a LOT of birds on it, but I'm having trouble with winchester about ordering a front sight. There rifled and it's fell off since last season (second time).
Times running out so I ran and got a truglo gobble stopper .665 for my Franchi I-12. Don't know what to expect but it was kind of late in the game to start experimenting. It is auto so I can send the hevi's flyin if I have to. LOL!!
