This question has come up before and the consensus is yes. But not all are believers and I
though this might help.
A few weeks ago a friend came by and ask if I could make his 30/06 shoot better without
re barreling. I told him it was a gamble with the factory barrel but I would try.
Using all the same stuff I decided to break it down and rebuild from scratch.
Using the factory barrel I set back the shoulder.015,chased the threads. leveled the recoil lug(
it was .003 to .000 depending on where I measured it),squared the tenon end, squared the
bolt recess in the tenon and re-cut the chamber until it cleaned up. Then I cut a new crown.
Next came the receiver. the bolt fit very well so I squared the receiver face and the recoil bosses
Then squared the bolt face and the recoil lugs. then after lapping the lugs I re assembled the
barreled action and installed it in the stock with a pillar bedding job to finish it off.
This rifle responded very well to say the least. It from a 2.5 MOA rifle to a 3/4 MOA rifle using
If you had this done by a smith it would be expensive and not practical but on a custom rifle
where you already have a lot invested it only makes sense to true everything to ring out the
best potential of the rifle.
I did not test between each operation to see what made the most difference but It tells me
that each exercise was/is worth the effort.
Most custom rifle
smiths do this in order to meet an accuracy standard but some don't.
so it you are contemplating a custom build talk to your smith and know what he intends
So with a reasonable good factory barrel and some work you "CAN" make a silk purse out
of a sows ear.
