Does anyone load for the .378?
I have a U.S made Euromark and looking for suggested starting loads for the 300gr Accubond.

Thanks!

I found some excellent information about the .378WM over on Weatherby rifle forums (search).

I could help you if you're needing 270 grain load.
Good Luck

I'm loading 104.5gr of IMR4350 with 270gr A-Frames in mine. What powders would you prefer to start with? I have access to a lot of load data for the 378 Weatherby but did not specifically see the Accubond bullets listed.

Hi Ed,

I have RL22, H-4831 and RL25. I also have some 260gr Accubonds.

IanD--On the 260gr Accubonds the only listing I found was with RL22 starting load 103gr mv2732 and max load 107gr mv2902.
On the 300gr bullets the data varied by company.
Speer--RL22 min 104gr max 110gr mv2670-2827
RL25 min 110gr max 116gr mv2724-2907
Nosler Partition--RL22 min 100.5 max 104.5 mv2590-2789
H4831 min 102gr max 112gr mv2624-2926
Hornady--RL22 min 106.6gr max 110.4 mv2800-2900
H4831 min 97.1 max 107.9 mv2600-2900
Sierra--H4831 min 103gr max 111.4gr mv2600-2900

I hope this helps at least to give you an idea of where to start.

Thanks Ed, much appreciated. I hope to get out to the range this coming week so will post some results.
