Finally got patterning that I have confidence in. Yesterday went out and shot Remington HeviShot 12ga in 3½" 1¾oz #5 shot and 3½" 1-7/8oz #5 shot in both my NOVA and my new NEF SB1-F10 single shot.

In the NOVA I used the factory full choke as that's all I have at this time.
In the NEF I used a StarDot ported choke. The factory tube and a TruGlo xtreme didn't pattern well.

Both guns are definitely turkey killers. I backed off (just for fun) to 49 yards and fired one at the target with the NOVA. I'd take a shot at that if conditions were right without hesitating. The 1-7/8oz loads patterned better in actual count and just by looking at the paper. All yardages were measured, not merely stepped off.
