22" or a tish less, 75 of H4831sc gets me to 2867 fps and that's a great plenty out of the lil case IME...

Could hammer it into the land of 29 but I see no reason to run something that hard anymore. Glad I've left those days behind.

Like any of the other WSM's within 100 fps of the old standard mags is about the end of the line.
