Why on earth not? Target shooting is target shooting. If a coke can is 2.5" diameter and 4.8" tall, filled with concrete would work out at about 3kg. If you shot that at one of the ranges we have access to (no calibre limits, only a 7000 joule limit), you would be limited to 880ft/sec - about the normal velocity of a .44 revolver ball.
All you would have to do is apply for a slot for a 2.5" calibre 'muzzle loading cannon' for target shooting. Unfortunately, being over 2" diameter, you won't be able to put it onto a shotgun certificate. I would be tempted not to mention the nature of your projectile - that bit is up to you. Sounds fun, though.
