NEED LOADS for 30-378 Accumark

Howdy all, I would like to thank everyone who responded to this thread. A lot of great advice and experience, good photos and stories. And nice to meet you all. Did some load development this past week, tried 3 different powders and 3 different bullets. Settled on 215 Hybrid bullets and H- 1000 powder. Had a great node with 101grs of H.1000, mild load 3040 fps but a .3 moa at 100yrd, o.a.l. 3.800 max for mag length, CCI250, new Norma brass. Again thank you all very much. God Bless AMERICA. đź‘Ť
That's awesome and congrats on finding a shooter. Best of luck on your future hunts and here's to many years of safe and successful hunt's creating memories!
 
No replacement for displacement the big 30 will out perform in every weight bullet W/bbl. length being equal, same thig as a Rem 6mm and a Win .243, 426 hemi and a 396 Chevy, simple physics..
Agree with the above. I own several 300 RUMS. And I'm currently considering acquiring a 30-378 accumark.
I'm running 215s at 3200 and change with h1000 out of a 26" bbl. No pressure, great primers, brass is on its 6th firing. My question…..realistically, what will be gained with the big weatherby case?

as I've destroyed two Weatherby actions.
Expand upon that please.

I've pushed 2 lug actions harder than some will ever believe. I'm not overly confident when looking at those 9 itty bitty lugs.
 
Have mine now for some 22-23 years also have a 300 Win Mag, 300 Wby Mag, 308 Norma and its the 30-378 DADDY of all the 30's out there for me anyway. Thats my 2 cents worth. Enjoy yous as much as I enjoy mine.
Have also a 7MM Wby mag, Wby actions , never a problem at least with the ones I have, besides I don't push my loads. If need be will go up a notch in calibers. Have the 338-35's and 37's sold the 50 BMG got to be a little too much for me now.

A lot of redundancy in those 9 itty bitty lugs!!!
 
Been shooting 180gr. Barnes for years with R-25. @ 3400fps. Gonna give StaBall HD and the 174 gr. HH and see if we can get a node up around 3500 fps. Talk about an elk laser, using an 8" circle MPBR is 521 yards! At that distance it's still pushing over 2600 fps and over 2700 Ft. lbs. @ 800 it's 2241 fps and 1951 ft. lbs. I'll take that!!!!
