I bought a keg of h4350 (upc# 3928850092). Next to the h4350 it says "hodgdon EXTREME powders. Hodgdon online notes max of 59.0 gr with H4350 in 30-06 using a 165 gr sierra HPBT. Sierra manual notes a max of 54.5 H4350 if i recall correctly for the same pill (i use the manual from the local sports shop thus dont have it with me). The keg label data matches the info on hodgdons site. Just the difference between Sierra and Hodgdon worried me. Any input would be helpful... I will likely put off loading tonight and call Sierra and Hodgdon tomorrow or monday if I don't get it sorted out.. Thanks! Wanna kill these ads? We can help!
