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 sizer

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.

Shotshell Checker works great

A friend loaned me one of these sizers at a match when I was having problems with my shotgun reloads. I ordered one of these and after checking and sizing my existing loads, I never experienced a problem with loading or unloading shells. This is a great product and if you reload, you need one.

Good quality and works great.

A bit expansive but the shotshell checker and sizer works well and is worth the price to verify that your reloaded shotshell was made correctly.

Highly recommend

This is a must have for anyone shooting Cowboy / SASS. Even factory shells aren’t sized appropriately.

Great product

This works exactly as described. It is made well. It was at my house within a few days of ordering. I should have found out about it sooner and saved myself a lot of aggrivation.

You need this! Not only shot loads, but does GREAT for crimped slug loads that widen the top a bit. A couple twists in this of gear, and all is well! I just check em real quick before boxing or storage and never have any issues with feeding. If you don't check em, then you can just take it with you in case you get that one shell that no fit!
