I read an old post that said use bench mark powder! I went to the hodgdon sight and could not find any reloading data for bench mark! Lots of different data for other powders for the 7.62x39mm ! I will be using the 123 or 125 grain v max hornady bullet! Any help with choice of powder would be great! I am also looking for places to find data online for this round! Hodgdon is the only easy place to find data for me so far! So any help would be great! Thank you Dale
