This is why you try everything...including oal and the .5gr makes a difference as does OAL
i tried the 43.5 with 2.800aol and the groups were no better than 43 gr load. every gun is different that .010" put me into the lands.
notice the cheapy 307" old sierra flat nose 150gr loads..that is over 2900fps and shot 4" higher than the other loads
at 350-400 yards the nosler would catch up to that 150gr..funny that 150gr load would punch a tiny ragged hole at 50 yards.. that was my tree rat load. pop the heads right off.
