I got responses from a couple of dealers, including 3Rivers and Brave Heart. The consensus is that the 100 grainers are a tiny bit smaller in diameter and that using extra glue should solve the problem. I’m wondering if that little bit of wiggle can lead to slight alignment issues. Trial would tell. Perhaps the best way to up the weight is to go with a heavier adapter, which would put the weight farther north anyway.
