I went out yesterday to test the first batch of 3" TSS handloads at 40 yards. These were 1-1/2 oz. loads shot out of a Remington 870 and a Pure Gold .555 choke.
I had to change pretty much everything about the 2-3/4" recipe, and I still need to work on them some more before I'm comfortable, but they are looking good so far.
T9s
254 in 10"
416 in 20"
T98s
213 in 10"
353 in 20" (this number is artificially low due to too small paper size which didn't catch the full 20" pattern...)
I think the T9s will be the way to go with the Big 20. They'll get much better penetration than Nitros 7s, with a much better pattern also.
