This is a 45-70 necked down to 375,will try the 375 this Friday w/245gr bore rider this is from a mould from Dan at MM,first time to shoot this barrel ,using water dropped ww w/FWFL for lube between 1900-2200 fps working up a load to try during deer season.Just for fun I bought some 270gr-.375 solids from Bridger about 2 months ago will work up loads for them also,they sure are long though.Any body here have experience with this round.
Thanks Sean

Nope, but keep me posted I have been looking at that cartridge for some time now.
