300 gr. CEB solids in .375 H&H

[375er]

Looking for what others have found for an accurate load with this bullet. Currently testing with IMR 4064. Open to opinions.

I prefer temperature stable H4895 when its available and H4350. Both render accurate loads in my .375 H&H rifles shooting 275 gr CEB Safari Raptors. While I have never loaded solids for my 375's, in .458 Win and Lott CEB Raptors and Solids shoot the same as long as I reduce the lighter Raptor loads by 1 grain of powder.

Fine Sirs, thank you for the information. I have plenty of time to experiment but prefer to skip rabbit holes that others have already explored. Thank you both!!

I loaded the 300 Grain CEB Safari Solid with 71 grains of RL15 for 2530 FPS. A couple things I have found; First, these bullets don't develop as much pressure as most traditional construction bullets, so I had to use 3 grains more RL15 to get the same velocity as 68 grains with 300 grain A-Frame. Second, be sure to crimp between driving bands (most likely 1st and second). If you crimp in front of first driving band you will most likely suffer from recoil setback of bullet in magazine box. The neck tension is not enough to hold these bullets in place, as they only contact the case on the driving bands.
