Looks to be one step away from allowing a remote operator to pull the trigger, which doesn't give me the warm and fuzzies.
And for this sort of precision a fairly difficult one to acquire. My personal example of the "do it 10,000 times" thing, about the number of rounds I fired in my high school rifle team and prior to that to get perhaps this good. Absent special talent, assume a few months full time with a "growing up shooting" foundation like myself. Without, I have no idea.
Maybe not out of the box, but mounting it on a motorized gimbal seems like an elementary exercise to me.
Having said that, yes, you are correct. Make it all remote; mount it on a drone. This thing is very close to being a particularly nasty piece of gear. Nasty in the sense that when we think of a "rifle", it's a guy with a small cannon and a long barrel pulling a trigger to attack something that he can easily see (and can see him). It's not a semi-autonomous weapon system reaching out from places unknown controlled by a person or computer yet somewhere else.
And a much greater environmental effect on the bullet, probably precluding the accuracy promised.
The 388TP is based on the .338 Lapua Magnum, I'd assume it's pushing 3,000 fps like the parent cartridge unless I hear otherwise. After spending some quality time with Google just now I couldn't find anything on the 338TP's velocity.
