When they say what is a type of gun is a 460--I'm assuming what they are really asking about is the Wetherby 460 Magnum which is a proprietary belted magnum big/dangerous game rifle cartridge made by Weatherby (the gun manufacturer) for their proprietary hunting rifle of the same calibre.
Look this is how you calculate these type of questions, you do 87/100 multiplied by 460 which will equal 400.2
