The problem with using a cratex pill is that it does not have to follow the rifling and would probably
take the sharp edges off the rifling. When casting a broach/lap it fits the rifling and the lands,
making it in 100 % contact and lapping all surfaces.
This is the reason we caution everyone about lapping, It is a good way to ruin a good barrel
if not done correctly.
Lapping should be done only to improve a poor barrel, It will never be a substitute for a quality
barrel. The saying "You cant make a silk purse out of a pigs ear" applies hear.
I know others that use a coarser grit lapping and are successful but I don't because if it is bad enough
to need a course compound I simply replace it. All I want to do is smooth it out a little and make it
clean up better/faster.
As in an earlier post I recomended experimenting on a Take off barrel to get the process down and
see the results before starting down this road.
It,s like Gun Smithing, If you don,t know how you probably shouldn't.
Just my opinion
