Re: Barrel Lapping Compounds
[ QUOTE ]
I doubt you will get anyone to fess up about using actual lapping compounds in a factory barrel. If you did enough lapping to get them smooth you would have to take an inch out of the throat area, muzzle area and have a horrible piece left in the middle that is probably over sized. I would classify the neco/tubb/JB sort of treatment as more of a polishing than lapping and still damaging at least. The lapping that is done to a a custom barrel is just not possible on a factory, pre-chambered barrel. It may be possible to get a 3" barrel to shape up a little but to actually get a decent barrel to shoot better I doubt your odds are very good. I will probably catch some flack for this but I have never seen anyone actually pull off lapping a factory barrel. just my .0000002 cents

I think that laping should be used only as a last resort
and knowing that it could shorten the barrels life by 2 or 300 rds should be considered.
And also if done wrong could ruin the barrel completely but
for a hunting rifle a barrel life of 1200 to 2000 rds is more than a lifetime for some hunters.
(Example) I just laped a winchester 25 WSSM that would not
shoot less than 3 MOA bedded,floated,crowned and with any load tested so rather than rebarrel lapping seamed like the
only thing left to try.
After lapping the 25 shot 1.361MOA with the best load tested
before lapping still not great but a lot better than 3MOA.
This was a very crummy factory barrel that had two bad places in the bore.
And with new test loads it has improved even more.
This barrel was good enough for use as a tent stake
as supplied by winchester so ther was nothing to loose
by lapping it but some time.
