Hi all. In the GMDR low level data section there is info for red dot and 170 weight cast Bullets but it’s for a 3006. I don’t own one ......they list red dot from 6-10 grains giving between 1000 and 1400 FPS .....how would I go about deciding on some red dot loads if I sought 1200 FPS loads in my 20 inch barrelled howa 308?
