Gas checks are a brass/copper cup placed on the base of cast bullets, especially designed for gas checks. Cast bullets designed to use gas checks can used without but bullets not designed for gas checks cannot be used with gas checks. The qualifier here is ...within the parameters of normal cast bullet proceedures.
The gas checks purpose is to protect the base of the bullet from the heat, pressures of the rapidly expanding gases generated by the powder. Think of it as a seal that grips the base of the bullet forcing the bullet ahead of it and the gases behind it. The copper/brass on the base of the bullet keeps the gases behind the relatively soft bullet.
You are in the right place to find the bullet you are looking for.
