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...

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

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...

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!

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

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.

The bullets must be run thru a Lee sizing die to press on the gas check. To get enough leverage to push the bullet thru, the die can only be screwed in a couple of turns. Round and pointed nose bullets are difficult to center on the punch. I had to make a sleeve to center the bullet on the punch and hold it there while pushing it into the die. Installing the gas check will cause round and pointed noses to get flattened. The gas checks work fine but are difficult to use on anything other than flat nosed bullets.

I bought these to use in rifle loads in the 32-20 on bullets cast .312 with a Lyman 311008 mold. They seem to work well. It has made it possible to use this mold for higher velocities. You do need to carefully press them on or they will go on crooked and some seemed smaller but it may of been the bullet bases.

They make the normal plain base moulds currently available into a GC version.
With these plain base gas checks you get two moulds for the price of one.
I install them onto plain base cast bullets in .005 step increments.
This allows me to eliminate the tearing that otherwise might occur if one tried to do the gas check installation all in one step.
This gives the gas check a finished look on the cast bullet.
