Wanted to resurrect my very first rifle, a pre-67 110L, among other things, re-barrel it. Gunsmith advised me I would need a new bolt as the old, pre-67 bolt face has a large rim for the half-moon extractor. Purchased a new bolt body, bolt face, retaining pin and firing pin. Assembled it all together and... cannot rotate the bolt down into battery. A closer look reveals the new bolt face has lugs measuring 1/2 inch long. The old bolt face has lugs 7/16 inch long. I'm thinking the lugs on the new bolt face are too long to rotate into the receiver. Anyone run into this before? Any solution or insights would be greatly appreciated. Dave
