The .300 Blackout is based off of a shortened 5.56x45mm case that is necked to .30 caliber. For AR-15 platform rifles and pistols it only requires changing the barrel to go from 5.56 to .300 Blackout. The Blackout’s main purpose is to be used at subsonic velocities in suppressed firearms. Many bolt action and single shot rifles are now being produced in this caliber as well.

The .308 Match is our small primer version of the .308 Winchester case. Many competitive shooters prefer the consistent velocities produced by small rifle primers. Like all of our other small primer rifle cases, we utilize our standard .080″ flash hole diameter, as we feel it gives better ignition with slower burning and harder to ignite powders, making it more user friendly than many of the small primer/small flash hole versions of this caliber

This is our Small Rifle Primer version of the 6.5 Creedmoor. The 6.5 Creedmoor was designed as a target caliber in 2007 by Hornady but has become an extremely popular hunting caliber as well. While it isn’t as long as some of the other 6.5 caliber short action calibers, such as the .260 Remington, the Creedmoor utilizes a 30° shoulder and very little body taper to help it achieve similar ballistics. The shorter length also gives it more versatility as far as bullet seating depth is concerned. Almost every major rifle manufacturer offers either a bolt-action rifle or a modern sporting rifle in 6.5 Creedmoor caliber due to its versatility and inherent accuracy.

Our SR6.5CM brass uses a Small Rifle Primer. Many target shooters prefer the Small Primer for the increased consistency and accuracy. While other small pocket manufacturers use a smaller than standard flash hole, Starline uses our standard .080″ flash hole, as we feel that it gives better ignition with some of the slower powders and in cooler conditions* (and you won’t be breaking off decapping pins either!)  The Small Primer version also maintains primer pocket size much better than the large primer version under higher pressures.

The 6.5 Grendel was designed for use in an AR-15 type rifle to offer ballistics similar to the .308 Winchester, with less recoil. This flat shooting round utilizes the inherently accurate, high ballistic coefficient 6.5mm diameter bullet. Its short case length allows it to use some of the longer, heavier match bullets, making this caliber one of the best choices for long range shooting out of an AR. With proper bullet selection, this caliber is no slouch in the field either, being suitable for deer-size game as well as varmint hunting.

Conversion of an AR to 6.5 Grendel requires a new bolt, barrel and magazines to feed the larger diameter cartridge. Several companies offer completed AR uppers and firearms, and reloading dies are readily available. Several manufacturers are now producing bolt action rifles in this caliber, many of which are built on “mini” actions, making for a lightweight rifle with plenty of range.

Our 6.5 Grendel brass uses the standard .080″ flash hole as opposed to a few companies that use the .060″ flash hole.

This case is very similar, except for the difference in length, to the .30 Mauser. Due to higher operating pressures, if the .30 Mauser cases are fired with hotter 7.62×25 loads in the CZ-52, it will tear the neck off some cases. 30 Mauser O.A.L. is .980″ to .985″ while 7.62×25 O.A.L. is .958″ to .962″. We recommend using bullets of .308″ diameter in our brass.
