Frankford Arsenal X-10 Large Primer Tube Kit 3 Pack

Anyone running a progressive press knows the session stops when the primer tube runs dry. Three tubes at 100 large primers each means 300 primers are staged before the press ever turns, so filling tubes becomes something done once at the end of a night instead of six times in the middle of one.

The X-10 tubes work with any progressive press on the market, so this is not a kit tied to one machine. Fill them at the bench while doing something else, cap them, and then load straight through without breaking rhythm.
