I've been using imr 4350 to load my 3006 .270 and 243 just looking for a new powder that works universally in theses calibers generally load 165 grain in the 06 130 in the 270 and 95 gr in the 243.some formulas would be helpful thanks
IMR4064 produced much better accuracy with bullets 160 to 180 grains in the .30-06. IMR4350 shoots bullets faster, but they don't land as close together on target than IMR4064 produces. Heavier bullets do well with IMR4350. What's more important; bullets shooting 100 fps faster or landing a lot closer together?
