Ruger Hawkeye barrel markings

[StevenK11]

It's a Left-handed Ruger M77 Hawkeye 30-06 Sprg in stainless with laminate stock and Swift 4-12x40mm scope.  Very accurate rifle too.  

I'm curious as to this additional marking on the barrel, and not sure what it means.   The marking appears to be put on after the 'bead-blast' finish because it is shiny metal in the grooves, whereas the other markings are the same satin color as the finish.

What is it?  A proof marking?  It kind of looks like an R with a partial circle around it.

A second question I have:  What is the purpose of the hole on the side of the receiver?  Is it there in case of a case failure to provide a place to vent the gases safely?

Yes the hole is for gas to escape if the case fails

Thanks for the reply.     I was figuring it was for that, but wasn't sure.   

The barrel marking thing isn't a big deal, but it does look nasty (pics don't show it clearly).  More like someone just wacked the barrel with a cheap marking tool and didn't do it right.     The other markings on the barrel look professional and even.

More importantly, the rifle shoots great and is reliable.

I would say this is "most" important.    Sounds like you have a real shooter there.

Thanks!   I don't hunt; just shoot targets at the range and collect firearms.    It has to hit bullseye's, but I also buy them on visual appearance.  Guess that's why I like single-action revolvers too.

I contacted Ruger and their response:

              This is a stamp to show we proof tested the firearm.
