Sorry, I've never shot anything heavier than 50 grain in my 22-250s, with 1/12 and 1/14 twist. I never could get any vmaxes to shoot like a nosler ballistic tip either. My rifles just don't like hornady.
Here is load info from the hodgdon/imr/winchester reloading data site.
55 GR. SPEER SP
IMR 8208 XBR
min 32.0 grains
max 35.8
