So ill be that guy, what problem does this solve that a high power airgun does not? Its only marginally thinner than some crossbows. And probably takes the same amount of time to load.
Looks interesting but I think his buffalo hunt was BS. Not much penetration on such a beast. Sure, it died, but how long did it really take to bleed out.
Now for some stealth SHTF sniper work, hmmm..... more concealable than a crossbow or compound.
My old man made one before these gained headway and were on the public market....simply put, it made us all giggle. Just another thing in the arsenal so to speak. It was deadly accurate and penetration was more than impressive. No doubt in my mind could use it for deer if needed.
