Years ago I shot some 90 grain 9mm bullets from .357 Magnum cases with full-power loads. I don't remember the powder or charge weight right now, but could probably still find it if that becomes important. The accuracy was surprizingly good. I think that the high pressure of the load I used bumped the bullets up to cylinder throat and bore diameter, producing the good accuracy.

In that regard, I suspect that 13 grains of H-110 under a 95 grain bullet is going to be more than 3% under maximum, and therefore not necessarily going to ignite well and make high pressure consistently. I wonder why somebody would choose that load for that bullet.
