I put the big Remington on paper for a couple of patterning shots today. My load was a Federal hull cut to 2 7/8", Fiocchi 616 (209 type) primer, 22 grains of Green Dot, SP10 wad, 3/8" fiber filler wad, 1 1/8 ounce of Eagle brand magnum #6. I got an actual hand pellet count of 253 pellets. I was very pleased with the results.
First shot was from right barrel with .046 choke. I shot a little high but achieved 236 pellets in a 30" circle at 40 yards circle for 93.28%.
Second shot was from left barrel with .045 choke. I pretty much centered the target and it put 234 pellets in a 30" circle at 40 yards for 92.49%.
