Update- Thanks to all for the replies.
I thoroughly cleaned the chamber and bore. In the bore I used JB bore paste on a flannel patch wrapped around a bronze bore brush and used my drill to polish the inside of the chamber up just past the neck. Finished everything with solvent and then dry patches until clean.
Today I took a factory Hornady 108 grain ELD Match cartridge and measured the OAL at 2.790” Colored the bullet with a black Sharpie, dropped it in the chamber and closed the bolt. Withdrew the round carefully trying to keep it away from the chamber walls.
The bullet had marks from the lands almost all the way back to the case mouth. I did this several times just to verify. So I guess I’ll give Ruger a call on Monday to see what they say.
