I am suspicious that at Rem SA mag lengths many of the newer high performance VLS, Hybrids etc. could end up with the ogive starting inside the case neck and /or be seated so deeply as to use up valuable case capacity. I'd have a talk with your gunsmith on your best option.
You can't push the 185gr fast enough to get the better wind drift values in the shorter freebored chambers. Even if you re-throat the chamber extracting a loaded round out of a short action is a b!tch.
