30/378

[McIII]

Hello all. I was just wanting to know if anyone was doing any loading for the Weatherby 30/378. I have an Accumark that I purchased about 10 years or so ago, and have been hunting with it regularly. It performs well, but I cannot seem to get the groups I want. My best load is 115 gr. of H50BMG with Fed 215 primers, and Barns Tripple Shock bullets. It shoots around a 1.25" group. Don't get me wrong, none of the deer have complained, but I think it will shoot better. Trouble is, with 115 gr.s per shot, I don't want to do a lot of experimenting. Has anyone found a good load that they are proud of? Thanks in advance for any answers.

I shoot big ole hairy wildcats and can tell you that Hogdons US 869 is almost a 50bmg crossover and is a lot more consistent as far as velocity spreads are concerned and much, much, much cleaner burning. 50BMG is NASTY and tempermental. IF you know somebody with Load From Disk program, they can plug it in for you.. I would think that you could drop 2 grains off your BMG load and start back up with the 869 and be just fine -I run a 6.5mm STW and find that I have to clean it about every 15 rounds with BMG...Hope this helps and happy hunting...............

I thought about after it I had already posted about the powder issue, but if rifle is a factory Weatherby, then they are chambered with a lot of freebore and with the combination of Barnes and the freebore part of the equation, then I would seat bullets out as far as your magazine well will allow. Barnes are notorious for liking almost no "jump" into the lands...
