And to think, "deerandblackbear" was (almost) one word in the books and catalogs. One theory is that when Remington introduced the .35 Rem, that was as close as they could get to .33 and .35 Win in their auto and pump. It has certainly outlasted them. Annoying that it is on its own head diameter. If there is anything more common to make .35 out of, I don't know what.
