@sgt_zimH4350 got me where I need to be with those low BC Normas. I think the issue with Magnum and 4831 is they're just too slow for my 22" bbl.
At southern Africa escarpment and elk altitudes, I should be right at 500 yards and still be around 2k fps and 1500-ish ft lbs of impact energy. That's farther than I'm comfortable to shoot at an animal anyway.
IDK why i didn't just start with CFE223 for the 308 loads. I'm getting a staggering 2875 fps with 168 gr Speer Gold Dots
I use the CFE with the 150s in my sons 308 for just a bit under 3,000fps.
No matter what I try with the 168s even with your load nothing will make them group less than 1.5"
Some combinations won't go below 2". Tried different powders, seating depth, primers cases just don't like them.
180gn round nose cut half inch groups all day so do the 125, 130 and 150s. Just something about 168s it don't like
