I extensively tested 240 and 300 grain XTPs a decade ago in 44 magnum and 444 Marlin
Both sub sonic and super sonic
The 240s were better at everything than the 300s
Both sub and super the 300s did not expand as well
Two 240s back to back in the 444 were a laugh
The front bullet went pretty well on target
I never really found where the back bullets were going
Then a few years later found the bullet holes in one if my sheds about 15° to the left of my 100m range
And it was a pretty good group
Robbie T and i were trying to develop a duplex bullet load for Bush stalking
Thinking two bullets from one shot had to be better ?
WRONG
