I shoot hundreds of shots in practice for every shot on game. Some of the cartridges I reload are very expensive. Also, I like to keep a lot of brass together. When I go to the range I like to have 50, not 49. But more importantly, I don't like chasing brass. I don't like looking for cases in the grass or on the floor of the range. I don't like having my cases on the ground where someone may step on them before I pick them up. And, I don't see any advantage to an ejector whatsoever. To quote Edwin Starr (but first recorded by the Temptations), "what is it good for?"

When I hunt I don't worry about a cartridge case, although I pick it up if possible.
