Just so you don't think I was kidding, I have #9.5 437/oz count TSS now. 12ga with 2oz of these are throwing over 400 10" numbers.
Here's the patterns from two more 20ga's I built and patterned today:
Both were 40 yard shots, with Remington Super Full Chokes, and 1 5/8oz TSS #9 reloads.
First 309 in the 10" and 226 in the 20" for 535 total.
Second 218 in the 10" and 289 in the 20" for 507 total.
