I agree most heartily with 264 mag. The boss is a great accuraizer but it's probably an answer to a question never asked.. If there I'd no remove it but install a non-vented shroud to avoid the hearing loss..and one shot is enough to do the damage,, a little at a time.. Also check the inside of the muzzle, as I've had several in the shop that were mounted out of alignment with the bore so badly the bullets were impacting the inside of the boss! Needless to say the accuracy was less than stellar.
