I timed your shot and came up with a time average of 4.5 seconds!
Pretty cool... And those Rice barrels aren't expensive at all. If I'm reading it right you can get one with the BP, 15/16" Octagon for about $300 - $350
Drop me a PM if you get a chance.
These Rice Bullet Barrels are INCREDIBLE Shooting Barrels, I have 3 of them, they are NO DOUBT my TOP DOGS. I love my Green Mountain Barrels, But my Rice Barrels Edge them out EVERYTIME. These Rice Bullet Barrels are “Match Grade” 4140 Chromoly Steel (Same as High End Centerfire Rifle Barrels) They are Left Hand Twist. Even the Breechplugs are CNC Machined from Solid Bar Stock, instead of CAST like most other Sidelock ML Breechplugs
