[QUOTE="BountyHunter, post: 338930, member: 12"] Understand your chamber throat is set by the reamer design, not the barrel manufacturers. Most "factory" chambers are set at max SAAMI and with the mftrs "most common" bullet for that caliber. It is normally impossible to have the same throat set for 150s and 200s both at .010 off the lands. If your throat is short, PTG sells a hand throater that can be used to lengthen the throat. Go slow removing .005 at a time and recheck 2-3x. Most guys building custom guns will load the bullet they want to try and shoot at either max magazine OAL if a mag gun or at the best location in the case for that bullet and send the dummy case to the reamer mftr to let him spec the reamer of that dummy. Reamers only cost less than $150 and you get to keep it. Pretty smart move on a $3000 plus gun build IMO. BH [/QUOTE]
