No, I do not have a chrono but was using LC -09 Brass with Wolf SRM primers and 25.0 grains of Hodgdon BLC-2 in a 20" Custom MatchGrade Machine barrel with 1:7" twist.
I am kind of surprised that the petals were not torn off since the slug was rotating about 300,000 rpms when it entered the hog?
I took out my micrometer and measured the length of some of the different .224 slugs I've been using just to see how long the copper Barnes TSX really is, here are the results:
Barnes TSX 70 grain - 1.040"
Hornady Match 75 grain - 0.992"
Sierra MatchKing 77 grain - 0.985
Nosler Competition 77 grain - 0.982
Barnes TSX 62 grain - 0.945
Nosler 69 grain - 0.900
Sierra 69 grain 0.890
As you can see, the Barnes are the longest slugs on the market.
