Holey Moley... I am still fireforming with 95gr Bergers and 41gr of H100V and based on back calculating bullet drop (6" drop from 100-285 yards) the G7 calculator figures they are going 3400fps. I did an 11 shot group and vertically they were within 1" so I can't imagine one could go with 48gr of H100V... Wow. I thought an Ackley chamber got you about another 10% and 41gr is listed as a Max load for the regular 243 Win ?
I would suspect you must be close to max load already. Better wear gloves and safety glasses...
