If you handload 6mm Creedmoor and you're chasing single-hole groups, neck tension is one of the biggest variables you can get a handle on. The Forster Bushing Bump Neck Die Kit gives you that control by letting you swap interchangeable bushings to size the case neck only as much as the job calls for. It sizes the neck and bumps the shoulder back for proper headspace in one pass, and the decapping assembly knocks out the spent primer at the same time. Working the brass less keeps your necks straighter, which pays off in better concentricity and longer case life.
Forster builds these dies the way they build everything, machined on precise lathes to tight tolerances, heat treated, and hand polished for a smooth, consistent feel. The bushings carry that same smooth interior finish so necks size without chatter or drag. Because the bushing sets the neck diameter instead of a fixed expander ball, you decide how much grip the bullet gets. Tighter for maximum bullet hold, looser if you're minimizing runout on a particular lot of brass. Forster offers bushings in .001 inch increments across a huge range, so you're never locked into one setting.
This kit comes with three staff-selected bushings sized .274, .272, and .270 inch, which covers most common brass and bullet combos right out of the box. The usual method is simple: measure the outside neck diameter of a loaded round, then subtract about .002 inch for your starting bushing. That leaves roughly .001 inch of spring-back for correct tension. Different brass brands and even different lots vary in neck wall thickness, so having a few sizes on hand lets you adapt without guessing.
The kit is cut specifically for 6mm Creedmoor, and it drops right into a Forster Co-Ax or any standard 7/8-14 press. For precision-minded loaders building match ammo or a long-range hunting rig, this is a straightforward way to take real ownership of your neck tension.
Yes. This kit ships with three neck bushings pre-selected by Forster's staff in .274, .272, and .270 inch, so you can start sizing without ordering extras first. Those three cover most 6mm Creedmoor brass and bullet combinations. If your brass falls outside that range, Forster offers bushings in .001 inch increments.
The simplest method is to measure the outside neck diameter of a loaded round with a caliper or micrometer, then subtract about .002 inch for your starting bushing. That leaves roughly .001 inch of brass spring-back for proper tension. Since neck wall thickness varies between brass brands and lots, it helps to keep a bushing or two on either side of your target.
A standard die uses a fixed expander ball, so you're stuck with whatever neck tension it gives. This bushing bump die lets you choose the exact neck diameter by swapping bushings, and it sizes the neck down only as much as needed while bumping the shoulder back for correct headspace. Working the brass less keeps necks straighter, which improves concentricity and extends case life.
It uses standard 7/8-14 threads, so it fits a Forster Co-Ax press and any common single-stage or turret press. If you run it in a Co-Ax, you won't need a shellholder. In a non-Forster press, use the shellholder recommended by your press maker.
