I reloaded several boxes of minimum recoil 163 gr. SP-BT .308s for my son's T/C pistol last year and they turned out to be the most accurate in his handgun by far. He wants me to reload the used brass with that same formula but when I printed the labels I wrote "163 gr. SP-BT". If I know more info - like Mfg'r. or any other special data - I always write it on the label. I've checked every source that I know and can't find a single mfg'r who produces 163 gr. .308 bullets. Any help would be appreciated.
