375 H&H and Winchester 748

[mritter]

Looking for feedback from those who may have used Winchester 748 in the 375, perhaps specifically with the Barnes 270gr and/or 300gr TSX.
Load data is listed in the Barnes manual and the powder seems to be available. Thanks in advance.

748 is great stuff, but also heat sensitive. Unless you do hot weather (summer in Texas) load development, keep your velocities moderate to avoid unexpected surprises.

748 is really dirty stuff but have not used in 375. My usage was in thousands of prairie dog rounds.
Used lots of 760 in the 375 with good results

Have you considered using CFE 223 in your 375.
Great and very versatile powder for cartridges from 222rem up to 375.
