This is a recovered Nosler 100 gr out of my 26 inch 243. They leave the barrel at 3208 fps with 46.4 grains of Ram shot Hunter powder. of course work up to it.
The superior BC of the 100 will really shine at anything over 300 meters
I have shot the 87 v-max chronoed at 3400 fps and 80 grain btsp's at 3500. IMO don't even bother with less than 80 grain. Those are for the wimpy guys with short barrelled 243's trying to set some speed record.
It is best to concentrate on one round
