I never said that the 30-378 was not a good cartridge,rather that it was a poor choice for a one gun hunter.I have owned a 30-378 and I own two 3000ultramags myself,but I have several rifles with similar trajectories to practise with in order to spread out my shooting and make barrels last much longer.The 300ultramag brass is also much cheaper than 30-378 brass.By the way all 30-378s do not wear the weatherby name.A friend owns a sako trg-s chambered in 30-378.
