55 and 70 noslers bts have to loaded out about .115 longer that 58 and 65 vmax and about .125 longer than a 60 sierra hp to get to the lands. If the noslers hit at a short coal the chamber won't lend its to those other bullets without eating powder capacity.
That's the problem with the .117 freebore hagar. 70 bts are almost 1/4" from the lands at 2.295" which can't be good.
Cavity Back Bullets does this to a PRI mag for a claimed 2.36 COAL
It's an old trick and it seems like any metal mag could be used.
