Backed load off a grain and shot a 550 in 10" and 316 in 20". Unsure if I am going to settle on this load but you got to stop somewhere. Lol Seems to be the kinda performance expected out of the 10 gauge. This has been a quest just to see how good we could get them and only that. We are aware it is overkill but using a ten, 12, 16, 28, and 28 could be considered overkill also as I use a 410 a good bit. The 410 was a really difficult shotgun to get what I considered acceptable and repeatable patterns at 40, the big 10 not so much. But it has all been enjoyable! Got to get my shot trap complete!
