Took my Mossberg 20 ga out to pattern for spring Turkey and wouldn't pattern for poop..tried 5 & 6 shot .hevi shot and nitro turkey..Turkey and full choke..frustrated a bit..picked up an 870 express 12 ga popped in some #6 hevi shot and did great..not starting a rant as lots of folks Turkey with a twenty, just wanting thoughts on the matter..besides I can always use an excuse for another shooting iron !!!
