What Causes Shotgun Choke Tubes to Lock-Up or Freeze-Up in the Barrel? (Part 1 of 2)

By George Trulock

I’m sure a lot of shotgun shooters have encountered this dreaded problem.

You start to remove the choke from your shotgun and it will not budge.

You increase the pressure on your choke wrench and still get no movement.

You eventually end up putting enough torque on the wrench that it causes your face to turn red and your arms too start to tremble. The choke still does not move.

You then find some sort of tool to give you additional leverage on the wrench and the darn choke tube still refuses to budge.

You start to wonder what you did to cause this problem!!

There are BASICALLY THREE THINGS THAT WILL FREESE UPA SHOTGUN CHOKE IN THE BARREL:

  1. Rust
  2. Residue build up from fired shells (unburned powder, fiber, plastic, etc.)
  3. Choke tube expansion (Creep)

If you want to keep your shotgun chokes functioning as they were intended, then TAKE CARE OF THESE BASIC MAINTENANCE ITEMS ON A REGULAR BASIS:

  1. LOOSEN & RETIGHTEN the choke on occasion. Even better if you REMOVE the choke and REINSTALL in the barrel on a regular basis. This will break any bond that is attempting to form.
  2. CLEAN CHOKE BODY and REMOVE RESIDUE from the threads with a stiff brush and solvent of some kind.
  3. CLEAN INTERNAL THREADS and CHOKE COUNTERBORE in the barrel.  USE BRONZE BORE BRUSH and SOLVENT.
  4. WIPE SURFACES DRY, then LUBRICATE them with a few drops of high quality GUN OIL.

Sincerely,

George Trulock
