The test results are in. I am preparing for an Elephant hunt in Botswana that will be done with my 8 bore (.83 caliber) muzzleloader. I am shooting an 1105 grain short conical bullet that is sized to bore size with a hollow base seated on top of 350 grains equivalent of Pyrodex RS. Before I found out about Microlon Products, I chronographed the load at 1545 f/s. After treating the barrel with Microlon Gun Juice per your instructions and not changing anything else (same can of powder, bullets from the same casting and sizing system) I measured the velocity at 1655 f/s. That is a 110 f/s increase in velocity due to the lubrication effect on Gun Juice. The velocity increase translates into a muzzle energy increase from 5855ft-lb to 6719ft-lb. Thank you for a great product. I can’t wait to try the other blackpowder Magic Bore Cleaner and UltraBlue Penetrating Gun Lube from Microlon Products.
