    375 BR I built on an AR -15 platform for hog hunting. 300 Whisper cartridge for comparison.

    I had the rest of the parts so I'm into it for the cost of the barrel, the reamer and dies.... and the lathe time.
    I use the same setup and switch out a 458 SOC barrel.

    What is the parent case? A 458 SOCOM or 6 BR?

    I found out that he was using 7mm br as the parent case to build the 375 br/whisper.
