barrel help

[ditchdigger]

Can anyone help ID this barrel. its on a Winchester m70 reciever and I would have thought if it were a factory barrel it would also have the Winchester logo.
I KNOW its a 300 win mag, I am wondering about the manufacturer
thanks

I can't identify it, but it is not a Winchester M-70 factory barrel.

JGG? JCC? JCG? (John's Custom Guns?)
is probably the gunsmith who re-barreled it with a blank, but I don't know who that might be offhand.

I am sure its JCC. I wasn't sure if blank manufacturers marked their barrels. Its an extremely heavy bull barrel. the complete rifle weighs in around 12 lbs
