Gas-Checked vs. Non-Gas-Checked Bullets: How to Make Your Own Ammunition

Video Transcript

" Now we’re going to be talking about two different type of cast bullets. One is gas checked as this bullet is and another is not gas checked. As you can probably notice, there is a small little copper cup at the base of this bullet. This particular bullet does not have one. What a gas checked bullet will do is the copper will prevent the base of the bullet from being melted by the hot gases as it goes down the barrel off the board. This will prevent the bullet from deforming and also here again, it will keep the lead from fouling the barrel. This bullet is an example what gets in a 45 ACP or 45 automatic. It’s driven at a much less velocity than this bullet would be, so you would not have to have a gas checked for this particular bullet. This will work just fine. This bullet is meant to be driven at 1000 feet per second or slower. This bullet can be driven up to 1600 or 1700 feet a second without very much leading in your barrel. "
