I am awaiting a new barrel ( 28" 1 in 10 twist Lilja) for my 340 Weatherby. This is not the most idea launch platform for heavy, long range bullets, but it is what I have. My muzzle velocity will be low; probably 2600-2700 fps. What is the minimum upset velocity for a 300 g. SMK in animal tissue? A better question may be -what does this bullet do upon impact with animals? Does it mushroom, fragment vilolently, or something else? My other option will be a 250 g Nosler Accubond. I can probably get the Accubond velocity up to 2900+ fps. I tried to contact Berger, via email, in regards to their forthcoming .338 options, but no response. Does anyone have data on the 300 SMK in anmals? Other than it stones them like lightning.
