IMR 4350 is a very popular rifle powder suitable for cartridges from the 243 up to the 300 magnums. It may very well be the most widely used rifle powder out there. 785 was probably the slowest rifle ball powder Winchester ever produced(discontinued). I believe it was similar to 4831 in burn rate.
What do you load for that you have no use for 4350, only pistols maybe??
.233 and 30-30
I have not done large rifle and do not plan on it since those I used to were for someone else.
For me the 30-30 and 44mag are ok for what I would want in the woods, Hog and close up deer.
I have always wanted a large rifle and shot some of my friends but realy have no use for one.
