Rammed,
Yes, good point. The brush does 'lock' - and the back-set works very well against the 'char' that happens within the first 8 - 10 inches from the breach-plug. This 'set' does reduce the life of the brush considerably, however. I go through three or four each competition season. My breach-loader is cleaned from the breach forward, just like a 'modern' firearm, so brush set isn't a factor in those.
