I'm loading for my 243 26 inch barrel. I have already found a couple sweetspots at a 100 yards, for a hornady 105 grain Amax with H4350, 39g and 40.5. I am going to load more to take them out further, i rechecked the Hodgdon site and for the same 1 in 10 twist 24 inch barrel, they say 35 to 37.5 max. My hornady reloading manual for same 1 in 10 twist, 24 inch barrel, they say 38 to 41g max. Like i said i have already loaded these and shot them from 38 to 41g and had no overpressure issues. Why cant these data places stop confusing me?
