Rebarreling my Remington 700 BDL SA 270WSM. Barrel of choice is 24” 8:1 Bartlein. I can’t decide between a 3 or 3b contour. This is a carry hunting rig so I’m thinking weight savings tell me to go with a 3. I know I could flute the 3b but that’s just more cost. Is there any reason a 3b would be better than a 3? Would it be more accurate? I plan to shoot the 140s to 150s bullets all the way up to the 170. Factory 24” barreled action in an HS Precision stock topped with a Leupold 4.5-14x40 was 8.51 pounds. I’d like to try to stay under 9 pounds with glass if possible unless I’m going to gain some accuracy… under 10 pounds for sure. Glass and stock are staying the same. Any advice on the 3 vs. 3b contour would be greatly appreciated. Thank you.
