It might make sense as a wilderness defense pistol, with solid bullets for deep penetration. Of course, that makes it a handier-to-carry equivalent of the M1 Carbine, no one's idea of a dangerous game gun, but pistols are in general underpowered for such use. Would this caliber be a better hedge bet than 10mm Auto?
The problem is if you want penetration on a thick hided, heavily muscled, and heavily boned dangerous animal, a heavier bullet caries a lot more momentum and bone breaking capability. The reindeer they shot in the video does have a lot of muscle and relatively heavy bones. However, it does not have a thick hide, just fur. Also, as you know, there is a big difference between taking a well aimed shot at a stationary animal and taking a shot at a charging bear, moose, or other type of perturbed beasty. When I see evidence this round can penetrate one of those animals musculature, AND break bones that will disable a charging critter, then I'll think about adjusting my thinking. I regularly hike in bear and moose country, and I have accidently found myself closer than is safe. I want a large heavy bullet that's going to pass through.
If this cartridge and platform have any application, in my mind it is with personal defense against humans. It does seem to have low recoil and a pretty decent capacity. But here's the thing, if I can buy a Glock 20 or 29 in 10mm, and run some really light and fast rounds through it like I mentioned earlier, why do I need an obscure vapor-ware gun that shoots magical mach 16 bullets? Same effect, different cartridge, less obscurity with the 10mm.
I'm biased. I just ventured into 10mm and the more I explore the possible loadings of that cartridge, from 105 grain pills zipping along at over 1800 ft/second, to 230 grain hard casts chugging along at 1200 ft/sec, I almost wish I had never gotten into 45 acp and 9mm. It seems to me I can accomplish anything those two cartridges can accomplish with the 10mm loaded differently.
Anything except find a VARIETY of different small concealable guns that are chambered for 10mm. Glock seems to be it, and I don't care for Glocks. I'm waiting to see what Springfield comes out with. I desperately want the HK P30sk or VP9sk to be offered in 10mm. It'll never happen though. If I really got my wish, they would be all steel guns.
All of that aside, I just don't see that this new cartridge will stop the threat any faster than any of the well established cartridges out there.
