The only extractor issues I have seen from a claw extractor on a 77 was from a 270 a bud used to single feed. The extractor had to push up over the rim of the brass and it developed a burr, this was after tons of shooting from a bench.
Smith told him what he felt was the problem and removed the burr. After that those of us w 77s made sure to feed them from the mag well.
