Jeremy,
I have only drilled two, one for myself, and one for a
customer, and I did put the weight hole in after they threw it,
on a frsh pattern, and both do not hit the weight hole. A friend
of mine, who got his drilled somewhere else, clips his weight hole,
about 2 in every 10 shots, but it did not affect his carry.
Good Luck
