The pain that can be inflicted by crescent butt plates is no joke. By the time you get up to .50 it isn't pleasant if you load heavy. I had a .50 with a "medium" crescent rear end and from the bench it left the shoulder bruised and sore. Yes, it did hurt when fired from a bench but the bruising/aching really showed up the next day. I wasn't about to try it prone! But from offhand and field positions the recoil wasn't noticeable; which was great since it was a hunting rifle for deer. I own a couple of rifles with those "quarter moon" butts, but they are a .32 and a .45 and are kitty cats. Other than wearing a padded shirt or thick jacket the only thing I can come up with is the traditional shoot-from-the-arm hold.
