Many shooters did not trust or like ejector on double rifles. Funniest reason Ive herd is the noise they make when kicking out the spent cases. Funny because two booming discharges might have tipped off the big game where you were. Another reason Ive heard that a ejector failure was considered a real problem if it occurred. Extractors were tried and true, with a brute force cam action to extract the case so you could remove and reload. If your Spring was weak or not able to cam the case out if swollen your gun could become a single shot or worse inoperable. And some just did not want to spend the extra money.
