A 1-11 will stabilize some very long Bergers, including some over 200 grains.
A lot will depend on the length of the magazine. I dunno about the latest Kimbers, but the magazine of the.300 WSM I had several years ago was too short even for Ballistic Tips to be seated close to the lands. My present Winchester Model 70, however, has a 3.05 inch magazine, which is plenty for just about any bullet.
