For grins I ran QL 44mag w/ 240 XTP loaded to Euro CIP 280 mpa / 40,600 psi level . Projected MAX loads were : 24.2grs I4227 , 21.0grs N-110 , 25.0grs W296 / H110 , 16.7grs N-105 , 21.5grs AA#9 , 21.5grs 2400 , 23.5grs Lil Gun , 20.5grs Enforcer / 4100 , 25.0grs 300MP , 24.0grs 5744 . Same level with a NOS 240 JSP col 1.580 projected max loads were : 12.6grs 800X , 20.5grs AA#9 , 22.5grs I4227 , 21.0grs 2400 , 23.0grs W296 / H110 , Lil Gun , 5744 , 21.8grs Enforcer / 4100 , 22.0grs 300MP .
Important to note these are projected NOT tested pressures & in NO WAY should QL or any other ballistics program be used as a loading manual . In OP's post I saw 25.0grs 4227 & thought WOW ! 4227 is noted for accuracy , not top velocities as it's too fast . Along with who shoots a 240 FMJ in 44mag ? Absolute cheapest jacketed 44 mag bullet capable of good accuracy is the Zero 240 , however it's fatter .430 vs most others .429 . Lee push thru .429 sizer fix dat toot suite .
