The Remington Duplex loads were, for many years, my favorite spring gobbler killer. But when PA banned the use of BB sized shot, I quit using them and went to the copper plated 4's in the Federal Mag loads. My favorite Rem. load was the BBX4. What a killer that was out to 50 yards with my old 10 ga. and my new 12 ga. 3 1/2" Mossy!
