My son put three under an inch with my Weatherby Vanguard this morning. 21 grains 2400, Lee 170 RNFP, powdercoated, gas checked, 50/50 ww/pure air cooled alloy, neck sized Rem brass, WLR primer 1850-1900 fps. Fouled, cold bore. He would have kept shooting, but I had him stop so we could enjoy it, never done it myself with cast. We’ve probably killed a dozen deer with this load over the years.
