[QUOTE="Rockbottom, post: 2784635, member: 85549"] Using some data from a Hodgdon Manual: changing the powder charge from the minimum 55.5gr to the maximum 59gr added 159 fps to the mv to a 125gr Nosler in a .264 Win Mag. That works out to 0.454fps for a change of 0.01gr. of H4831. A ballistic calculator shows the change in bullet drop at 1000yds is 277.15" vs 277.24" if the 59gr charge is off by 0.01gr. Your results may vary. [TABLE] [TR] [TD][RIGHT][/RIGHT][/TD] [TD][RIGHT][/RIGHT][/TD] [/TR] [/TABLE] [/QUOTE]
