Mike, as usual, really enjoyed your this video and frankly, a bit surprised at how well the conicals grouped. ..
Now, this is not a test, just trying to glean from and understand your technique as I don't shoot C&B's very often.
Can you elaborate on your use of a felt wad on RB's and not the conical?
As you mentioned, you had a full charge of powder but if you hadn't, do you use corn meal?
Looks like you did not use Crisco or equal over each cylinder port. Do you ever use it?
If you would prefer to PM me on these questions, that is fine with me. ...
Thanks and;
Be Safe !!!
