Here it is:
378GNR rechambered 375 Win barrel 14" w/ brake
375 cal. 260 grain Nosler Ballistic Tip

Best results of 5 loads tested between 62 to 64 grains IMR 4350. Range was warm 68� no wind, and sunny. 63 grains of IMR4350 printed a 3 shot 1.0725 group gross at 100 yards and .6975 net(2 shots were .5085 gross and .1335 net)Average velocity was 2001 fps. This was my first serious shooting with this cartridge and I am impressed. (Did not know I could shoot so well.)

Will try other bullets soon. Ya gotta get one!
