Title: new barrel, any suggestions?
Post by: bow-n-head on March 27, 2009, 05:21:56 PM: I have a 300 H&H in a winchester 70. I think the headspace is streached and need to put a new barrel on it. The problem I see is the new barrel is going to cost more than the gun did to begin with. Does this sound right to any of you?

I would spend a couple of bucks and get a headspace gauge (field guage). Unless you've cleaned it to death a 300H&H will not wear out a barrel in less than a couple of thousand rounds. If it is really a headspace problem and your rifleling is still good you can have the barrel set back a turn and rechamber the barrel.

As far as a new barrel you can figure $400 to $600+ to buy a new barrel and have it installed.

Why do you feel you have a head space problem?

It is easy to over size(if your a reloader) magnum brass as it headspaces on the belt and it is easy to set the shoulder back too far. Backing off your sizing die a little will stop case head seperations.

If you don't have any problems with the partially sized case then you can size the once fired cases just enough to barely touch the shoulder, again using soot on the nack and shoulder to tell you how fare you are going into your sizing die.
