I am reloading for an Elk hunt, will either shoot 180 or 200 gr bullet (Nosler Partition) - I would like to tighten the grouping, and do not want to go down to a lighter bullet. Started at the SAAMI OAL and working my way down in 1000's of an inch on the 180's If you reload, what have you found to be the most accurate seating depth ? Appreciate any feedback. Thanks
