Amen to that!  Hugh got .333 bullets made for him from Barnes, but it
took a long time to get them so another of our bunch, a machinist,
made a swage to reduce .338 bullet down to .333.  We used an arbor
press at first, but found out that a RCBS rockchucker had enough
mechanical advantage at the end of the stroke to nibble away and push
the bullet through.  These swaged-down bullets were surprisingly
accurate for having undergone such a messy procedure.  We all agreed
that a .338-06 would be the way to go if you were starting from
scratch, but Hugh already had the .333-06 picked up in a trade and it
was sort of a challenge to make good with it... and he
certainly did!

Ernie, keep us posted on how this turns out. You ought to really have
an excellent piece for dropping the big beasts...  Good Luck!
