Hello, I have a Pardner SB1 20ga full choke single shot shotgun. I would love to take it turkey hunting in a few weeks but am having trouble finding a load that patterns well out of it. I've tried winchester and federal 3in mags in #4 and #5 shot but am having groups that would cover the whole bird at 25 yards. I don't really need to shoot any longer than 25 yards but I would really like to get the group smaller. Someone told me that the size shot doesn't matter much as long as the grouping is fairly tight. He recommended trying #6 or #7 shot and said they might group better. He said Federal makes a turkey load with a flight control wad that might make a difference but I'm not sure I want to buy into specialty turkey loads unless they really make a big difference. Does anyone have any info on what might shoot well through this gun? Thanks for any and all advice. I love this gun and am sad that H&R is no longer around. They made quality products at great prices.
