Tetra

[johnwayne]

If a barrel, 22 rimfire or centerfire, has had Tetra treatment in the past can it be successfully fire lapped?


Thanks

  It is MIGHTY slow going, but you should be able to knock off the high offending spots and improve the barrel some.   

Tetra is awful good, and almost defies wear including lapping, and it cannot be washed out with any kind of solvent..
