Just sent my MRC 1999 30-06 off to Clearwater Reboring to have it rebored to 35 Whelen. Rifle has a 24" # 4 fluted barrel, so I am not too concerned about barrel wall thickness.
I was curious about weight reduction and their process for altering the caliber mark, so I email their Company and Allen informed me that based on his calculations barrel weight would be reduced by approximately 2.57 ounces when rebored to 35 caliber on this 24" barrel. As for altering the caliber mark, he stated they normally use a 3/16" end mill, to mill a pocket just deep and long enough to remove the old mark. Then the new caliber mark is placed on the bottom surface of this pocket using a New Hermes pantograph engraver. Reboring job will take approximately 16 weeks. Must be a few rifles ahead of mine. My rifle wears a HS Precision stock which is a little on the heavy side so I am considering replacing it with one that is a little lighter, sometime this winter. Haven't decided which stock company to go with on this project yet. Still need to look at some options.
I keep telling myself that I will work on just one more rifle project for this season and call it quits for the year, but for some odd reason I just can't stop planning out another and another and another..........Anyone ever have this problem?
