Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

Product Information

All 50 count listings of Peterson Cartridge casings come in one of their plastic ammo boxes.

Made in the U.S.A.

Designed to fill the gap between 6.5 PRC and 300 PRC, the 7mm PRC follows in the footsteps of its older brothers. It fires long, heavy for caliber bullets, 160gr to 180gr. The 7 PRC round fits in a standard long action and boasts more consistent velocities and longer barrel life. There is a long list of gun manufacturers making the 7 PRC or you have the option of switching out the barrel on your 7mm Rem Mag or 300 Win Mag.

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. 

This is not loaded ammunition.

7mm PRC Brass

By Devin M. on Feb 27, 2024
Amazing, high quality brass from Peterson. I have a few loads ready to go with Hornady 180gr ELDM and 190 & 195gr Berger. Can’t wait to get to the range and do some load work ups.

Excellent Brass!

By Greg G. on Feb 21, 2024
Extremely consistent and long lasting brass.

I load several calibers and my go to brass, if available, is Peterson. My 7 PRC will shoot to its potential using this brass because of the brass consistency which is second to none. Thank you Grafs for making this great product available and thank you for your great service. I’ll be back!

Peterson 7prc brass

Can’t say enough good things about this brass or Graf’s overall. Was very satisfied with my first online purchase from Graf’s initially but then Graf’s reached out to my cell phone to double check my address was correct before sending out my order. I appreciate the top notch customer service. You made a customer for life!

Very nice brass!

By Greg D. on Jan 10, 2024
This is my first batch of Peterson brass and so far I am very impressed. The primer pockets are very tight which bodes well for longevity.

Outstanding Product and Customer Service

By Matthew M. on Dec 21, 2023
The team at Grafs was amazing to deal with. Quick response to questions and quick to ship the product. Being out of Pittsburgh, PA I was offered the chance after my order to tour the Peterson Cartridge facility and was amazed by the process and how much care they take in ensuring their product is top-notch. Huge thanks to David for giving such a great tour. I have used many other products over the last 30 years but thanks to Peterson and Grafs outstanding service they now have a customer for life.

7 PRC brass

By ROSS C. on Oct 16, 2023
I received my brass very quickly from Graf. I'm still breaking in my rifle and haven't loaded any as of now but, I opened a box, nice packaging and weighed and measured all 50 pieces and inspected each one. From what I can tell these pieces measured and weighed fairly consistent and all look ready to be loaded once I run them thru my preload process.
I'll be seating on my Amp Press and this will tell me how consistent they will be. I will say they appear to be visually equal to my Lapua brass for my other PRC's so I have high hopes!

Peterson 7mm PRC brass looks and performs great. Would buy again. Fast shipping excellent product.

super nice brass

By John R. on Oct 13, 2023
Great brass. It took awhile for this 7mm prc brass to hit the market but after receiving, it's was worth the wait. fast shipping too from Grafs.

Great Brass!

By Forrest N. on Oct 13, 2023
This really is some of the best brass on the market. It comes well packaged and is consistent in both weight and length. While I do size every new piece of brass, this is so in spec that it takes very little sizing. The flash holes are also very clean and consistent. This is likely the best currently available brass for the 7mm PRC.

Brass looks great

By Joshua M. on Oct 13, 2023
I've only loaded up a few at this time. Brass looks great and prepping has been perfect. The case mine came in was broken with several piece of plastic in the shipping box so probably dropped in shipping or just prior to shipping, but that doesn't appear to have caused an issue with the brass.

No Worries

By Pepper M. on Oct 13, 2023
Hadn't used Peterson brass before. Great packaging and initial performance A+.

High Quality Brass

By Brenen H. on Oct 12, 2023
I've never used Peterson Brass before so was a bit apprehensive about ordering. Turns out, this is about as good as it gets. Very high quality brass. No regrets!

Peterson 7 PRC brass

By ROBERT O. on Oct 10, 2023
Peterson brass is exceptional. Run a mandrel through it and shooting sub .300 groups without any additional prep work. Weights and dimensions are super consistent and appreciate the box they arrive in. Graf's came through on the back order and even reached out to make sure I still wanted the brass before charging my CC.


By Nick G. on Oct 04, 2023
Best packaging i have seen cant wait to work some loads.

Excellent Product

By Danny T. on Apr 22, 2023
First time using Peterson, very impressed. Even the packaging to protect against dents and dings is great. Worth the extra cost.
