reloading a 30-378

[haugenna]

Is this a factory accumark Weatherby?

I have brass that has been reloaded 8-9 times in this gun.  They hardly stretch and require little if any trimming.  The base swelling is what makes them unuseable. 

108.5 grains of Retumbo with 180gr accubond will produce about 3350fps. Federal 215M primers.

Best group was under an inch at 300 yards.

try www.reloadersnest.com they have several loads for the 30-378 only load a few at a time its hard to find loads that shoot like factory ammo but eventually you'll find what your gun likes. I also agree with using heavier bullets I had no luck with 165 grain

Just remember to use the Federal 215 primer, a very slow burning powder, and stick with the heavy bullets (180-220). This caliber just isn't efficient with the light weight stuff.

I have look at that caliber a lot! Almost bought one right before I found my new 340wby. york is 100% right stay away from bullets lighter then 180 in that caliber. The ones I have shot all seemed to like 200g bullets. I would also look at the h50bmg powder in loading for it. Very slow burning powder and my friends that shoot that cal really get some good results. I know Dale on here is shooting one. Think he is shooting 180 tripple shocks, you might quizz him about that load if you are wanting to try barnes bullets in it.

They blew right through that bear. That was the first animal I shot with it. It is a sako and I am amazed at how little recoil. My son has shot his a lot more and is using 180 and 165 triple shocks. I honestly don't have any solid data to report yet. I have decided I am going to change scopes and shoot it more. Not happy with the scope that's on it, I am just used to other scopes. But it is too sweet shooting to let it just sit around.

Thanks for the information I put a long range 6.5 by 20 50mm scope on it and just got my dies. I have some 180 and 200 accubonds and thought to try them first they work well in my 300 wby. Thanks Dale we got our 7 sendors shooting to fast and they blew right through deer. I am trying to figure how high to sight it in at 100 yards I have a turnet knob on it.
