GFP requires 2200 ft pounds minimum. My program doesn't have a 52 cal listed
I have this ballistic sheet on file for a 460 grain bullet with 90 grains of T7. If I am getting 1500 with 90 and 460, I am betting you will get in the 16-1650 fps with the 375 if not more..
But, wait I Shot some .475-350 grain Lehigh's from my 52, but the information is on my other computer... I'll switch and get back to you...
Look at this bullet... there is also a 350
