Hired Gun,
Believe me, the 375 Allen Mag is sitting here in front of me on my desk on paper. This one has been just begging me to send the reamer print in for the build. With the right bullet, a 375 Allen Mag would give you everything the 338 AM would ballistically but with a significant increase in kenetic energy and frontal area.
Right now the only thing holding me back is a viable bullet. By that I mean a 380 to 410 gr ULD RBBT. Unfortunately, not good news from Wildcat bullets on those dies though so for the time being we are leaving things on paper.
No sence doing all the work to throw a 300 gr Sierra BTHP out there that will not even handle the impact velocity. SHE would be fast as hell though!!!.
If there is interest there will be a 375 Allen Mag here soon. Again, it is my personal opinion that it would be a better round then even the 338 Allen Mag and I think the 338 is about "it" as far as ballistic performance is concerned currently, even including the 50 cals.
