I'm running a little short on my go-to powder for my normal loads for my 308 Win using the 168 grain amax (42 gr. of RE-15) and was wanting to try another powder. I have plenty of IMR 4831 on hand. The Nosler reloading manual gives load data for the 150/155 grain bullet ( 48 gr. - 52 gr. of IMR 4831) and for the 180 grain bullet (46 gr. - 50 gr. of IMR 4831) but none using this powder for the 168 gr. bullet. My question is could I not start between these two loads ( 47 gr. - 51 gr. of IMR 4831) and as long as I started my load development at or near 47 gr. be perfectly fine since the 168 bullet falls right in the middle of the load data for the 155 gr. and 180 gr. bullet?? I'm not terribly concerned about accuracy so long as it will shoot around 1 moa as I will only be using this for whitetail deer at ranges under 150 yards. I am an experienced re-loader but have never made a practice of working up a load recipe that my reloading manual didn't call for. Any advice would be greatly appreciated.
