I don't laod the 7-08, but I do load a lot of 7mm RM. My experience has been tighter groups with near max, to max charges of slow burning powder, with light to mid weight bullets, 100 gr. - 145 gr.. The best accuracy I've had has been with 120 gr. bullets and maximum charges of RL22, probably not the powder for 7-08. But I would think RL17, IMR-4350 would offer some good velocity coupled with excellent velocity. I would try to seat up as close to the lands as you can, and then work back if needed until the groups tighten up.
