Check vmaker5/6/2023 PB Checkmaker™ ( stands for “plain base” bullets) dies use thin aluminum beverage can material or thin copper. The beauty of the my PB version dies is you can take advantage of inexpensive FREE BEVERAGE CAN thin metals. I say this is promising results for the first 12 rounds total loaded. The soda can PB gas check was still on the bullet. No leading what so ever and it’s hard to see but I recovered one bullet folded in the bottom of the dog food can. I’m pretty happy with that since I’m way out of practice handgun shooting. ![]() Out of six- 4 holes hit black at bout’ 2.560″ x 2.112″ center to center. ![]() Next, set up a target at 35yds, off hand with target shown. The first six shots I popped dog food cans off hand (2 hands standing) at 35 yards with no problems. Flared the mouth and charged through the charge die. LEE standard carbide dies, no factory crimp. CCI 300 primer crimped in the crimp groove with an OAL of 1.705 inches. I loaded 20gr of IMR 4227 behind a 305gr Keith (group buy square groove recreation) AC WW speed green lube, Checkmaker™ 45PB Pistol caliber- soda can plain base gas check, sized to. Got around to doing some loading and a little shooting with the 305gr Keith and the 45PB Pistol aluminum can gas check shown above. The ones on the right are a LEE group buy mold for the 45ACP I believe (.454 dia). On the left is the well known LEE TL-452-SWC that I had cast up a long time ago and lubed with LBT blue soft (.452). I’m starting with 2 styles of bullets used for the 45 ACP. Just takes some experimentation to find out what works best for your bullet and setup. I’m going to some extremes here show what can be done, but everyone has to work within the limits of their alloy hardness, metal thickness, sizing die process, and how far you are sizing down in diameter, etc. You can even hone out the gas check shank recess on an shank mold and convert it to a plain base (PB) mold. It’s like getting a whole bunch of new molds to try. Your old plain base molds can now go where they’ve never gone before- a whole new frontier never explored. ![]() This allows you to use one plain base mold and have the best of both worlds with a plain base cast bullet, and a PB gas checked bullet all in one, plus make extremely accurate gas checks with free metals. The Checkmaker™ “PB” (plain base) version dies are made to use with thin free beverage can metals to form your own gas checks for plain base bullets. Using the Checkmaker™ PB “Plain Base” Dies
