Sig Sauer Match Grade 300 Blackout 125-grain Open Tip Match ammunition (part no. C300A1-20) is built by Sig Sauer for shooters who want precision-level consistency out of an AR-platform 300 Blackout build. The open-tip match bullet is machined to tight tolerances for a consistent center of gravity, the same design philosophy used in dedicated match ammunition for bolt guns, just scaled to a 300 Blackout case. This load is built for tight groups at the range or in competition rather than hunting or defensive expansion. It’s a strong choice for shooters running a precision 300 Blackout upper who want factory ammunition that doesn’t compromise on accuracy.

Frequently Asked Questions

What does Match Grade mean on this load? It means the bullet and load are built to tighter tolerances for consistent, repeatable accuracy compared to standard practice ammunition.

Does the OTM bullet expand like a hollow point? Open tip match bullets are built for accuracy, not expansion, so they behave more like a target round than a defensive load.

How many rounds are in a box? Each box holds 20 rounds.
