Bill-

I wish I could add more performance information to what I've shown with my guns. I have seen very little information anywhere on the loading and shooting of the sixteen bore black powder rifle. Seems every time I get out to shoot the bore rifles my chrono gets bitchy. I've thought of getting a screen light for it to ensure that there's consistent light to allow the eyeballs to properly meter.
I need to call the manufacturer too to make sure I have exhausted all possible field troubleshooting protocols as well. You'd think that a projectile larger than 5/8" diameter would easily trip a chronograph...

All in time.

Both my guns have straight grip, fairly straight layout stocks as well. Recoil doesn't seem to me to be an issue.
And for what it's worth, I really like the straight grip for these guns.
