New territory---belted mags

[Zero333]

Don't worry about larry wills die unless you're using once fired brass from another rifle that will not fit into yours.


After the initial firing the headspace moves to the shoulder not unlike non-belted cartridges so don't sweat it and load it like any other. Just get yourself the Hornady Headspace comparator so you know how far you're bumping the shoulders when re-sizing. This will avoid any case stretching above the belt.

Here is a pic of a case I sectioned just to see if it was stretching above the belt after many re-loads. (never mind the short neck, I chopped it for something else)

Notice no brass thinning at all. The Hornady headspace comparator is worth the money.
