Anyone with experience with the "Walker" choke opening method (adjustable reamer and T-handle from the muzzle end unpiloted (except by the reamer blades). Can anything be accomplished this way besides making a mess and changing the POI? Brownell has this system and the bore piloted system and as usual the riskiest is the cheapest. I want to open up a Merkel 200 both barrels. I believe the choke is taper all the way (no parallel after) and not talking a few thou here. It may go to Mike Orlen in the end.
