I run True Blue in my .40 and .45s. For the sake of simplicity I wanted to run it in my 10mm as well. The only other semi I have that I load for uses the same powder as my revolvers, which are all magnums and all use 296 with very good results. True Blue lists a load for 180gr XTP in the .40 but nothing in the 10. Based on that it seemed to me it should work fine in the 10, but with zero book data to start with I was p hesitant to try. So I asked people that know more than I, excellent load data here ...

In my 1911s Ive worked up to 9.3gr True Blue, CCI 350 & 200gr XTP. Seems to be more accurate than me, feels good and zero pressure signs. My chrono died so no numbers there yet but I'm happy with this load
