I would skip the xtremes. My ts hates them. I have had the most luck with 180gr black bullets. 4.5 n320. 1.115. My 2nd choice would be 190gr ibejiheads 4.1 hp38. 1.110. I have to load mine really short to feed properly in my gun. Anything longer I get failure to feeds. Most ts owners I believe load around 1.120-1.125.
