no way, I'd rather take a great chamber over a great crown.Yes, if you want to preserve the accuracy of your barrel.
Well thats a REALLY BAD idea. The crown is the most important part of a barrel.
just use a cleaning rod that doesn't damage a steel barrel......I'm on year 6 of just free-ballin' a brass rod on every rifle.
$30 for a $1 piece of plastic is crazy to me.
