30-378 Weatherby and 138gr Hammer

[Baseball11]

REALLY.

You asked for information on using a bullet size that was Never meant to be shot out of a 30-378. And a Very Well Known Wildcatter give you information, and you are looking in books to Verify that information.
Start where he told you and work up.
I used Beans recipe in a 300RUM using H4350 to get 124HH to over 4000fps.
Start where he suggested and work up.
BE CAREFUL.

Will do. Thanks
Oh I'm still doing research too

Butterbean is the opposite of QL, he is helpful on hammers
