It is an amazing powder for a ball powder, isn't it. The .375/.444 is one I've had a hankering to chamber in something for some time now.
: I've a .32 SPL 1951 m94 Winchester that I might convert to something like that. My little Big Bore94 in .375 Winch. is a nice little rifle in it's own rite, and I thought the same chambering or on a larger case might be nice for a 24" bl. in the older but 98% condition 94. Although it's ballistics will be restricted due to the action, it would still be a resonable performer.
