Peterson 7mm BR Rem Unprimed Brass Rifle Casings
The 7mm BR calibre is a highly efficient, inherently accurate round, which doesn’t require much powder. The balance between the powder charge, bullet weight, barrel length and related harmonics results in a calibre with outstanding accuracy.
Spurred on by the requests of David Fricke of Lehigh Defense and SSK Firearms, Peterson has added 7mm BR Remington to its growing family of rifle casing calibres.
Lehigh, known for making specialized, high-performance bullets, began making bullets for the J. D. Jones-designed Whisper line of cartridges – which are necked up from 7 BR casings. Some years back, J. D. Jones, of SSK industries developed several efficient dual-role cartridges, the .302 Whisper, the .338 Whisper, .375 Whisper and the .416 Whisper. These are all made from necked-up 7mm BR Rem casings. The dual role refers to the fact that they can be loaded subsonic, or for high velocity.
According to Fricke, “Remington made the XP-100 bolt-action handgun, and one of the calibres they chambered it in was 7mm BR, which became very popular with Silhouette shooters. Remington also made the 7 BR casings which people like to neck up to the different Whisper calibres. But the Remington brass hasn’t been readily available for the last decade or so.”
Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
