Setting back a CF barrel

[Shane Lindsey]

Anyone ever have a carbon fiber barrel set back to give it a few more rounds?
I have a 300 RUM with a Remage set up and it has starting throwing shots. Curious if this is possible or time for a new one?

Only about 700 rounds on it, but has been fed N570 for the majority of its life.

How far did you set it back each time?

Did you cap the barrel end or just go with it as is? I cut a Christensen CF barrel down and just re-crowned it. It is a low volume shooter so haven't seen any adverse effects yet...

Following. Ordered a C6 barrel for a Savage with an extra inch on the shank end just for this purpose.

That is brilliant forsight. I wish I would have thought about that, but never thought I would burn up a barrel.

What cartrige?

Depending on the barrel maker, they should be able to provide you with a print showing the contour of the actual barrel steel under the CF. Some get skinny/thin really quick while others have more gradual taper from the chamber area to the straight part of the barrel. You should be able to set it back safely a couple times easily.

300 WM. Running 215 Hybrids either with H1000 or N570. We'll see what happens.

Did you shoot the barrel 800+ rounds each time, before your set it back/rechambered it?

Or does the barrel have a total of 800+ rounds on it?

Thanks
