Brian, have you actually used this rifle on deer? The reason I ask is that I have found that even a relatively mild cartridge, like the 8X64S, is excessive for the 150 to 200 pound white tail deer we have here in West Tennessee. I, too, have a 9.3X74R double rifle, but I would no more think of using it for deer than I would my .350 Griffin & Howe Magnum or my .350 Rigby Magnum. I bought mine with the idea of using it on driven wild boar, but at my age and given my health problems, that dream is rapidly fading. Still, I feel no temptation to use the rifle on deer. My .250-3000 Savage will do the job with ease and far less meat damage.
