Hello fellows. I lurk here often and learn lots. I have a question regarding headspace on a 338 win mag in a T/c Pro Hunter. I understand that because of the action design they will not be built very tight. However, I recently purchased the 338 barrel for my prohunter in stainless, installed it etc. I had it out for a few test fires yesterday. Upons returning home I inspected the cases as normal for loading and much to my amazement 4 out of five are cracking above the web of the case.
I then removed the barrel and inserted a new unfired brass in the chamber. The case head sits about .009-.010" below the breech face of the barrel. I thought hmm for a single shot this should be flush. I then took two of the fired cases pressed them in the chamber one at a time firmly, measured how much they protruded. They protrude about .009-.010" from the breech face of the barrel. Even if the barrel closed up flush to the rear of the action I would still have a .010" case stretch. Right now it is stretching the cases .018-.020" way too much. Any one else come across this.
I would assume returning the barrel is the next step????
Thanks
