If you had bought these two years ago you would have received the same dies as seen here but with one appreciable difference. Today RCBS sends you two dif expander balls. The one already installed will be 310 cal and the one included in a small bag will be about .3065 cal and it is intended for those with 308 barrels shooting 308 bullets. Now if you read any reviews on RCBS dies from two years ago they would have told you to order and extra expander ball for the bigger 312 bullets in the mosin because all the loading manuals and dies were set up for the Finnish 308 mosins. But looks like RCBS is catching up with the times. Gone are the days that the only mosins on the market were 308 finns. The huge wave of Russian 312 (311) mosins is clearly something they have been keeping up with. We shall see if Forster is just as in tune with the times when that set of dies comes.
