Thanks for the comments everyone.
tdbru, as stated in the original post, reformed cases averaged 15 or so grains heavier in both SR and LR 7.62 cases. I reduced loads from the get-go to achieve the same velocity as with Grendel cases. None of my loads, including those using Grendel cases are maximum. Neck turning has not been necessary so far as a bullet will easily slip into the necks of fired cases indicating proper dimensions. I've also been annealing before reforming and plan to reanneal after each firing if needed.
