Hodgdon lists the max load as 73 grs. of H-4831 in Win. brass.I am loading Lapua brass which seems to hold 2 grs. more water.Can the charge be increased safely because of the increased volumn of the lapua brass?Plus I seat the bullet longer than 3.34",3.375")so that gives more space.I have shot 78 grs. with no visible pressure signs and good brass life.My rifle has a 25" Hart barrel with a minimum SAAMI chamber.The load clocks at 3085 fps.Am I skating on thin ice?Quick Load shows around 60,000 psi.What do you think?
Thank you,
