I promised to report results on this activity. I'm pleased with the
results. The accuracy of a decent but inexpensive rifle was
significantly improved with one of the several loads tried today.
There were also some loads (different powder) it didn't shoot well at
all, though it has never shot any load so badly that it'd miss COM on
a deer at 200 yards, which is too far to be shooting deer with a .243.
I think after bedding it is now accurate enough to be used on varmints
out to 300 yards.
