I am going to take the rifle to him tomorrow for closer examination. Since he told me he was a world record holder at 1000 yds with the 300 Hart, I suppose he must know what he is talking about. I do know they are very nice people, and bent over backward to help
Bobby built a 30 Hart for me years ago. I had the 2nd gun made from their reamer. His was the first.
Ballistic wise the gun did fine, accuracy was another thing. I had RW Hart build a 16.5 Light gun for Williamsport and IBS. After getting my butt kicked I sent it off to Clay Spencer who made it into a fire form gun for my other (2) 300 Weatherby's
Get this, my chamber was different from Bob's and all 3 guns Clay built for me were perfect!
Just watch the headspace and pressure on it but if I were you I'd really consider the dies.
By the way, what world record does Bobby have??
