If you want a .243/6mm:

Get a used Savage. Rip the barrel out and put in single shot follower. Screw on a Brux (or whatever) 8 twist barrel in 6br Norma. Shoot Berger 105 hunting VLDs over anyone's SR BR primer and 30 grains of Varget. Load it 10 in the lands. Assertions that all rifles are different notwithstanding, it'll shoot bugholes. Accuracy problems will become a thing of the past.
