HOLLOWPOINTER INSTRUCTIONS
www.forsterproducts.com
Bullets are hollowpointed for improved expansion on impact. Hollowpointed rounds are very effective for hunting.
Hand-drilled hollowpoints expand better than factory-molded hollowpoints. Hollowpoints also may be used to finetune bullet weights for more accurate loads. This case trimmer accessory may be used on factory or hand-loaded
ammo. It may be used with the Original Forster Hand Trimmer, the Classic Trimmer, or the Power Case Trimmer.
FOR USE WITH ANY FORSTER HAND-OPERATED CASE TRIMMER
Begin by fastening your Forster Case Trimmer securely to a bench or board to allow the free use of both
hands. (If the Case Trimmer is mounted on a board, it can be held in a vise so that the trimmer can easily be
set up or put away.) Insert the shank of the drill into the pilot hole of the cutter shaft. Tighten the pilot set
screw against the flat on the shank of the drill. Next, insert the proper collet into the collet housing. With tension on the collet released, insert the base of the loaded cartridge into the collet. Place the guide bushing
over the nose of the bullet. Move the drill into the bushing hole. The drill is now accurately centered on the
nose of the bullet. Hold the guide bushing against the nose of the bullet so the base of the cartridge is seated
firmly against the collet. Tighten the collet screw.
To set for the depth of the cavity to be drilled, start by moving the drill into contact with the bullet. Loosen the
stop collar coarse adjustment set screw. Position the stop collar so that the distance between the bearing and
the stop collar fine adjustment screw is equal to the desired depth of the hollowpoint cavity. Tighten the coarse
adjustment set screw. Drill the cavity by turning the crank assembly while applying steady, inward pressure.
F
OR USE WITH THE
FORSTER POWER CASE TRIMMER
Start by using the Power Case Trimmer lineup bar to line up the Power Case Trimmer base with the drill
press spindle. (See your Power Case Trimmer instructions.) Next, install the special hollowpoint drill into the
drill press chuck. With tension on the collet released, insert the base of the cartridge into the collet. Place the
guide bushing over the nose of the bullet. Bring the drill down into the bushing hole without touching the bullet. The drill is now accurately centered with the nose of the bullet. Now, use the collet screw handle to lock
the collet tightly and hold the cartridge in place.
To set for the depth of cavity to be drilled, start by moving the drill into contact with the bullet. Move the drill
press adjustable stop until the distance between the adjustable stop and the fixed stop is equal to the desired
depth of the hollowpoint cavity. Drill the cavity. Retract the drill several times during the drilling operation to clear
chips. (Application of a little kerosene to the drill point will help to keep lead shavings from sticking to the drill.)
SUGGESTIONS FOR DEPTH OF HOLLOWPOINT CAVITY
1/8” Drill — Tests indicate that magnum loads should be drilled 1/8” deep for good results. For lighter
loads, it may be desirable to drill a deeper cavity.
1/16” Drill — Drill a maximum of 1/8” deep with heavy loads. For lighter loads, it may be desirable to drill a
deeper cavity. Maximum depths should be approached with caution.
Extra long bases for hollowpointing long cartridges and extra short bases to be used for pistol calibers are available.
