      Hornady's Lock-N-Load system covers the measuring side of reloading — the tools that tell you what your rifle actually wants rather than what the manual assumes.

      • OAL gauge and modified cases — for measuring the distance to the lands in your own chamber. Seating depth relative to the lands is one of the biggest levers on group size, and it is rifle-specific.
      • Bullet comparators — measure from the ogive rather than the tip, which is the only meaningful way to compare seating depth between bullets.
      • Headspace bushings — for measuring shoulder bump on fired brass, so you size just enough and no more.
      • Case lube — One Shot aerosol, which dries and needs no removal.
      • Powder handling — bushings and powder-through expanders for progressive presses.
