Fired 4bore with 760 gr light round ball with
fiber wads under it, using 150gr Blue Dot
and shotgun primer case. Just starting loads
for testing operation. Hardly no recoil,
like a heavy, beefed up blank load,
could go much higher with that light
of round ball. Will have pics of the muzzle
blast and the gun shooting from the side,
using heavier slugs in a week or so.
In Owen's 4bore double,that uses same case
size they use max of 110gr of Blue Dot
with 2000 gr slug. Ed
