Just wanted to drop a note to say that I am not set up to form 375 Allen Xpress brass for customers. This wildcat is basically a 338 Allen Xpress necked up to 375 cal. Performance wise, it will match a 378 Wby but in a much shorter OAL and with much stronger brass and get the performance with around 10-12 grains less powder. Just a heads up. Doing load development on a customers APS Raptor Stalker right now in 375 AX using the 235 gr TTSX and 350 gr TSX bullets so will post results on that rifles load development. Have not posted data on my 375 Allen Xpress yet.
