Product Information

This is a Bulk package of Peterson Cartridge casings, they will not come in one of their plastic ammo boxes.

Made in the U.S.A.

Remington hit a home run back in 1962 when they introduced their new Model 700 bolt action rifle, along with a brand-new belted magnum cartridge, the 7mm Remington Magnum.  It became an instant hit with big game hunters and shooters largely due to its versatility and longer barrel life compared to Winchester’s .264 Winchester Magnum.  Fifty-eight years later, the 7mm Remington Magnum remains among the top selling and most widely produced magnum rifle calibers. 

Derek Peterson, President of Peterson Cartridge states, “We have been working on belted magnums for a while now, and with some lessons learned and a few tweaks, we released our .300 Win. Mag.  The 7mm Remington Mag. was logically next on our list.”  He continues, “We wanted to provide belted magnum shooters the same level of quality casings as the rest of our product line, and these are no exception. Give them a shot and let us know what you think.” 

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.

Peterson 7 Mag Brass

By David F. on Mar 30, 2023
Great brass, a little pricey but in this shortage, that is to be expected. It is working much better than Sig brass if that helps anyone. I'm not turning necks or using precision dies and with this brass I have got by extreme spread in velocity down to 10fps or less. Fast shipping.

This is amazing brass. It was well worth the wait. Very uniform weight from piece to piece. I would also like to say Thank you to Graf and Sons for keeping me on the list and notifying me when the product came in. That kind of service in this day and age is what keeps people coming back. well done
