WHOA! What's wrong with this 1917 (keyholing)

[hagar in SC]

Is it severely copper fouled? The copper can cover the grooves while acting as a kind of lubricant making the bullet skid over the rifling. I woulld clean it really really well, it may take a couple of days with Sweets, Kroil and JB bore paste.

I had the same problem with my P-14, including keyholing at 25 metres. Had it re barrelled. It's now a nice shooter.

Know where I can find a new military-style barrel for a 1917?
