I guess these old guys have never heard of fancy BC`s of ballistics...

If one should load smokeless in these gaugerifle cartridges..should it be shotgun powders...or fastburning riflepowder??.

I wonder if a "little gardenload" could be done in the 10 gauge with a simple round ball??

Could the 10 bore be loaded with two roundballs in each hull??(multipurpose load..hahaha)

If/when I get to reload this 10bore "thing" should I preferre shotgun primers or rifle primers
a la Fed 215 and such??.
