1. Good checks

   Posted by KBH on Jan 25th 2026

   Ordered 500 to try, never used PB checks before. Sage's directions that were included seem right on. checks do go on square and look good.

2. Great for 327 Federal Magnum

   I use these plain base checks on Lee 90 gr SWC for use in 327 Federal Magnum. They install easily and work very well. I am very happy with them.

4. Just the thing for 30 caliber plain base bullets

   Posted by Mike B. on Mar 9th 2023

   This is just the thing for the 30 caliber plain based bullet ... It turns a PB mould into a GC version which allows one to push the envelope should one wish to... Its design is just the thing that one is looking for to turn a PB mould into a GC mould...

5. Perfect for my revolvers.

   These gas checks work great for my cast bullets for my 32 S&W long and my 327 Magnum loads.

6. Just the thing for 30 caliber plain base bullets

   Posted by Unknown on Jan 23rd 2022

   If you have a plain based cast bullet that you want to try to push faster than 1600 FPS, or that maybe you are using a very soft alloy, & want to try to see if you can minimize any potential leading... This is just the item to fill that perscription for that issue.. Try it you will most probably like it...

7. A good solution for the plain base problem.

   Posted by T Pilakowski on Jan 18th 2022

   I purchased these to add gas checks to some plain base .30 165gr bullets I found to be a little on the soft side. Installation was simple. Put a .309 size die, with the correct top punch, in my Lyman 450 and an hour and a half later 500 gas checked bullets sat in the box. Now if they just made these in .25 caliber.

   Think I covered the main points in the headline pretty well! This is my 3rd time dealing with Mr. Sage. Deal with trust!

9. .30 plain base checks

   Posted by john R Jeffries on Dec 9th 2021

   These checks easily apply to 311008 and crimp into place when sized to .313 for use in my 32-20. Limited testing (25 rounds) showed no difference between plain base and GC

10. .30 Caliber Plain Base Aluminum Gas Checks

    Posted by Colt Deon Lee Packer on Nov 24th 2021

    These .30 caliber gas checks allow me to put a gas check on a 30 Caliber plain base cast bullet, prior to the final size & lube process.
    
    I install them onto plain base cast bullets in .309, .311 & .312
    
    This allows me to produce bullets for .30-06, .30-30, .308, .303 British, 7.62x54R Mosin-Nagant & .300 AAC Blackout.
    
    Have had no problems run the bullets through the Lee Bullet Sizing & Lube dies. This gives the gas check a finished look on the cast bullet.
    
    The price of these gas check are the lowest I have found on the internet. So I will be doing more business with Sage's Outdoor in the future when I buy more gas checks for the rest of my bullets that I make for all of my guns. I produce bullet for all 16 of my rifles and pistols.
