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.

NOTE: If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, Peterson recommends you try the 6mm Creedmoor SRP. While they do not suggest loading over SAAMI max pressures, Peterson's small primer pocket 6mm Creedmoor have proven to hold up over SAAMI max pressures when tested in their universal receiver.

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.

Awesome brass just hard to come by

By Naris N. on Dec 06, 2023
There is nothing further that I can add to the quality of this brass. This is my first time using Peterson and the only reason to switch is because it's hard to find these but they do last.

Quality Brass

By Tony C. on Nov 24, 2023
This brass is consistent and of high quality. I'm running this in an AR10 in 6mm Creedmoor and have never had a problem as long as I full length size.


By Darriel J. on Nov 17, 2023
Super nice brass. Easy to FL size back, holds neck tension when annealed. Very good brass.


By Leonardo G. on Dec 27, 2022
I purchased this brass because of curiosity of the brand. Welp, impressive is an understatement. If I can find Peterson brass in the caliber I’m wanting brass for, it will now be my first choice. Everything from packaging to the cases and weights of the cases exceeded my expectations.

Great brass. This is the second caliber I have purchased now.
First was 308 SRP. Think I'll stick with this brand price and quality why go elsewhere.

Great packaging Best brass you can get

Very Nice Brass

By Allen B. on Sep 21, 2022
Bought the 6mm Creedmoor brass and it has been very consistent in size and quality. Shot 100 rounds so far with low sd's and it seems to be just as good as Lapua. Like some of the other reviews, the packaging is far better than lapua, haven't had one single dented neck.

Outstanding brass

By Charles H. on Aug 22, 2022
First purchased Peterson Brass for my 260 Remington and was impressed with the consistency and having it come in it's own compact 50rd ammo box sure is a plus. So when it came to getting brass for my 6mm Creedmoor, Peterson (SRP) was a real no-brainer, and just like last time, there was little to be disappointed with.

Peterson 6mm CM SRP Brass

By James W. on Feb 26, 2021
My new goto brass. The cases were every bit as consistent as Lapua, They are holding up to repeating firings very well and are generating very good number. I will be getting more of these.

Peterson 6mm CM brass

By Steven M. on Dec 08, 2020
This is high quality very consistent brass. The weights were all very close to each other, packaged very nicely in a nice ammo box.

Top Quality Brass

By John D. on Sep 24, 2020
Uniform weights of each case and well-packaged. This is my go-to source for 6mm brass. Top competitive shooters seem to agree. Can't wait to hit the range with fresh loads!

6mm Creedmoor SRP brass

By Kevin D. on Sep 12, 2020
This is super quality brass. It is what I use for PRS match’s. It is great to get the ammo box, very little prep work. I always size just to make sure of consistent neck tension, but that’s it for the prep.

Great brass, small primer pocket, comes it's own box

Peterson 6mm creedmoor SRP brass initial impression

By David C. on Apr 05, 2019
I compared the Peterson brass to the Lapua 6.5 Creedmoor I have been resizing and I am impressed.
Flash holes are uniform, case length is very consisten. 1 particularly interesting point I found is that the Peterson brass chambered in my Odin Works AR barrel much better and more reliably. I have been having problems w/ the Lapua having high pressure symptoms even while using published loads. I plan on using Peterson brass for my AR10 and Lapua 6.5 resized for my RPR 6 creedmoor going forward. Check out

Peterson Brass

By Mark C. on Mar 26, 2019
Very good brass. Very consistent in length and weight. Cases are prepped and ready to go. Mouths are inside chamfered and look great. I have several calibers of Peterson brass and all brass is very good. Highly recommend.

Seems to work as good as Lapua

By John N. on Mar 08, 2019
I have always reloaded Lapua Brass, never had an issue, So I did want to try Petersons, So far the quality seems really good, I have some in 6 creedmoor now, the 260 I got had done well, I will have to shoot it allot to see how long it lasts !

Peterson 6mm Creedmoor brass

By Ed H. on Dec 13, 2018
Weight and measurements were really consistent. My first groups working up loads (3 shot) were 1/2 to 3/4 inch at 100 yards. Great brass and the ammo box was a bonus.
