I usually just blow off the RUM rounds as being far too inefficient for the powder, components, and recoil investment. However, with a very long barrel and a bucket full of slow burning powder it may be worthwhile to try. Especially with all the new high BC bullets available to go with the properly twisted, high quality barrels you can get these days...
Yes it would be fun, but heavy.
8lbs. Hodgdon 869 and slower powders maybe BMG stuff, 190gr.+ bullets, 8tw.
