If you're a reloader, why not work up a reduced load for the Waters. I had a 10" Whisper for a little while and was not terribly impressed with the lack of blast and recoil. Of course a carbine barrel would tame significantly. I can tell you for certain that the 125gr BT is "Deer Deadly", at least in my Herret and 30-30AI, and I'm sure it would be in the Whisper as well.
BTW, If you're loading your Waters with a ball powder, just going to a stick powder may reduce the blast considerably. GOOD SHOOTIN', Walt
