yes. there is one i've watched on youtube that paints, does some neat color compositions.. wait... can elephants swing swords with their trunks??
the British have been making large caliber rifles for India and Africa for way over a hundred years. it would probably be easier to write a list of calibers that they have NOT built. i made a faulty assumption about it being .50 BMG. most govt agencies don't go out and buy exotic/prehistoric caliber firearms for park employees. those both look like recent manufacture bolt actions, esp the one on right in synthetic stock..Neither .50 BMG, nor S&W .500 Mag.
