Finally got to fire a few rounds through my Mossberg 410 with 24" factory full choke. I had on hand Browning #9 TSS, Federal #9 TSS, and some handloads in 9.5's TSS. Best I could do at a laser ranged 40 yards was 105 in 10 @ 40 with the 9.5's. The Brownings were decent at 95 in 10, and the Federals were no good at 32 in 10. Decided to send barrel to SumToy for him to thread and choke. If I can't get 150 in 10 I will just hunt with my 20's. Unsure how to post pattern pictures or I would post them. I am sure that the Brownings or the Handloads would do fine if you kept your max to 30. The Federals were terrible but the new box that I bought had one round were the over shot card was not seated properly and leaking buffer. That is not the round I shot, I shot one that looked loaded properly.
