The fact is that the actual bullets do the killing.A better bullet acting within the velocity/energy parameters of the cartridge/rifle hunted makes a better mousetrap.

The complication is when the bullet may damage the shooting platform as discussed and cussed above.Think I'll stay with the Woodleigh's and possibly the driving band bullets as the cutting edge technology available for my Double.Barnes mono bullets seem like they would be the hardest on the bore and "structure" of a Double rifle.I would even have a concern over the solid wall of the partition in a Swift A Frame obturating a Double's barrel!
