and you can get jaxketed velocities from the 30-30 by following the above advice ,all of it.
all 20 suggestions are right.....
i have used b-wax alox and carnuba,
parrafin,and moly
grease and b-wax.
parrafin,b-wax,moly,lithium, carnuba, lanolin, and atf combinations.
to exceed jaxketed velocities in the 30-30.
alloys from 50-50 through 4%sn/6%sb all work fine also.
as do powders from bullseye through whatever you got in burn speed.
you just gotta narrow the window down to your specific needs.
