In the process of buying a non fluted sendero barrel in 7mag,what can you guys tell me about these take off barrels?Thanxgun)
Is it crome molly (Black Finish) or stainless ?
If it is CM they are normaly good (I allways check them between centers for runout
to see how much straitening was done at the factory ) normaly if they are more than
.005 or .006 thousandth I reject them.
I have seen them almost .020 thousandth's off and on the stainless fluted barrels
the worst was .053 out of being strait.
The unfluted barrels seem to be straighter than the fluted ones.(It must be the process
they use).
Straitening a barrel is common for factory barrels but most custom barrels are rejected if
they are not strait or outside is turned after barrel has been straitened.
Also I lap all factory barrels ,stainless or crome molly if I am reinstalling them and touch the chamber with the reamer to true it up.
If the proper test and then good smithing is done they can be made to shoot well.
