Both rifles are chambered for 105 gr class bullet.
I'm shooting the 80's in my Factory Savage F-Class 6MM BR rifle.
The 90's in my Custom 6MM BRA Kreiger barrel Fire Forming the Brass.
Amazing how well the 90's shoot fire forming. My initial test @ 100 yds ,2 shots into the same hole.
This was with the bullets .009 ITL's. Since the initial load / seating test. I have shot 1 "UBR 243 Target" at 100 yds. shooting in 6-10 MPH winds. I was able to shoot a Score of 60 w/4X's. This is just a Local club shooting centerfires for some bragging rights.
