If you cast your own bullets, Hornady Crimp-On Gas Checks in .270 Cal (part no. 7050) are built to protect that investment. During sizing, the gas check crimps onto the base of the cast lead bullet, sealing propellant gases away from the soft lead and shielding the base from deformation under pressure. Hornady has offered gas checks in this format for decades, and bullet casters still reach for them because the fit is consistent from check to check. Each box holds 1,000 pieces, enough to keep a serious casting session running without a mid-batch parts run.

Frequently Asked Questions

What do gas checks do? They crimp onto the base of a cast lead bullet before sizing, sealing propellant gases and protecting the base from deforming under pressure.

Do I need a special tool to install these? No — the gas check crimps onto the bullet base during normal sizing, so no separate tool or step is required beyond your usual sizing die.
