Borescope images/videos seem to be popular.
I have a sweet Winchester M70 USMC sniper tribute in build.
Im not looking to kick the bag in on the smith so lets not go there (yet).
The rifle is beautifully finished and bedded. Its actually a great shooter in 30-06 but I had two problems with the barrel work.
The barrel itself is a Douglas, .308, 1/10 premium grade. was sent to the builder as a blank to have the shank done, extractor cut and finish cut/crowning.
First issue I had with the rifle was the inability to have it extract any sort of match ammo reliably. Feeds and extracts Federal 150 grain hunting ammo just fine, will feed but wont extract Lapua 167 grain match ammo - I have to beat slap the shit out of the handle to open the bolt, wont even feed my reloads (168 SMK) that feed/extract fine in two Springfield 03s and a Garand, will feed FGMM 168 30-06 but I have to beat the bolt in order to open/extract.
So my first concern was a chamber issue and the smith was very responsive working with me.
Than I got a Teslong borescope.
This barrel has plus or minus 150 rounds fired.
The video is from chamber to bore for orientation.
I kind of blow quickly through the chamber, not much to catch there with my untrained eye.
The Douglas looks pretty rough for "Premium" but puts bullets in tight groups.
It looks to me that the barrel was not "sealed" prior to bluing. The darkness in the lands I assume to be bluing not carbon.
The real anomaly occurs at the muzzle......WTF is happening there?
It looks like it has been counterbored with a chisel.
When the builder saw the video he said he had no idea of any problems. He ordered a new Douglas barrel and is rebarreling the rifle.
Any ideas, looks like the barrel spun on the indicator or something. Hideous. Surprised it shot as well as it did.
The vid....
