A simple tool to check and re-size 12 Gauge shotgun shells

  • One end checks reloaded shotgun shells to precise SAAMI 3" specifications
  • The other end easily re-sizes the shotshell if needed
  • Dramatically reduces ejection problems in SxS shotguns
  • Aids feeding of shells in pump or lever shotguns 
  • Made from high quality aircraft aluminum
  • Simple to use shot shell case gauge and sizer. Just drop the loaded shell into the rimmed end and let it fall.  Good ammo will easily slide in AND out.  If not then simply re-size the hull on the other end and check again.
  • Re-sizing simply requires the shell to be inserted about a 1/4" into the knurled end while twisting and applying light pressure
  • The re-sizing end tightens the crimp points that tend to unfold with used hulls.  Does NOT remove material or increase case pressure.
  • 12 Gauge Only
  • Use prior to loading shells in belt before each shooting stage

If you are shooting a double barrel shotgun with manual eject and need fast reloads for competition this checker/resizer is a must have.
Must have tool

Every shotgun owner should have one of these in their range bag. SASS shooters and skeet shooters this is a great tool to check for chamber fit and reverse to tool to straighten out ill fitting shell casings. Money well spent. IMO

Really like this product.
Perfect

My Lyman 12ga checker is very good. This is far better as I can squeeze slightly deformed hulls back into spec. to facilitate quick and easy loading into my coach gun.
Works Great for CAS!

I used this to neck down and size the shells for my last cowboy action shooting match. It worked great! I only had one shell hang up after shooting nearly 100 shells. All the others fell out with a little shake. This is a HUGE improvement. Thanks!
The standard and completely needed

The standard for shell checking and adjustment for cowboy action. Also very useful for setting up and adjusting reloader. Adjust until the shells drop easily into the checker.

I've seen other more experienced cowpokes using this tool and knew I needed to have one! It works better than advertised. You will not be disappointed with this tool. It is perfect for Cowboy Action Shooting or any other 12 ga. endeavor!
