  • Reviews

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
  • Proudly Made in the USA

Shell checker works

After seeing the fast shooters using the shell checker I finally got one and it is worth the price. If you use it every time it saves the occasional problem with an out of spec shell.

Yes, it is worth it

I initially hesitated buying this because it seemed a little high for a case gauge. I was an idiot. I should have bought this years ago. The gauge lets you know if that "fancy" ammo you have that "shouldn't have any issues" will work or not, and it will fix it if it doesn't pass.

This made my open shotgun actually run. I absolutely love this.

This works as advertised. I found lots of shells that needed sizing and this did the job for most. The only thing I didn’t like is it’s hard on the hands. You almost need gloves especially when you do 100 plus shells with my non-farm hands. Still it’s the best thing out there.

Used for the last shoot. Wow what a difference.
I shoot BP so most of my hulls are cast-offs. This made a big difference in loading and shucking.

I saw a friend of mine using this and ordered one for myself. my 12 ga shells get slightly coned with using this and I have more confidence speed loading. Highly recommended!!
