And a pair of chain nose (needle nose to most people) pliers inserted into the case mouth in the closed position and turned makes a wonderful case mouth expander. I have pretty much quit using other methods since I heard about this.
That's an idea. I am curious why the .44 loader I have comes with an expander, but the 7.62x54r doesn't? Best guess is they expect that cast bullets are more likely in .44 and boat tailed, jacketed in 7.62.
Have to admit, haven't opened either up to read yet. Packed them for an upcoming move. Last I used a Lee Loader was for shotshells, decades ago. Bought both as "part of the purchase" of the guns. Don't like to be without some sort of reloading for guns I buy.
