Peterson Brass 7mm BR Remington Unprimed Box of 50
Product Information
All 50 count listings of Peterson Cartridge casings come in one of their plastic ammo boxes.
Made in the U.S.A.
Match-Grade is a standard that must be held throughout the entire process of manufacturing some of the most consistent, accurate, and durable brass rifle casings available today. From Peterson's small batch production lines to their quality control department, to your bench, and on to the range. Match-grade is the standard that Peterson strives to achieve so that customers can maintain that standard all the way to the target.
NOTE: All Peterson SRP casings feature a small flash hole in the diameter of 0.060” vs. the 0.080” flash hole found in their LRP casings. This means you will need an X-small/ Undersized Decapping Pin to deprime these casings.
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.

By Chuck H. on Sep 25, 2020This is good stuff, haven't loaded it yet, but it checks out excellent. My OCD will require primer pocket and flash hole uniforming, but it doesn't appear necessary. Same with the neck. Brass arrived well packed in good, reuseable 50 round plastic ammo boxes, not loose bulk pack.
I'm satisfied with this brass and would recommend it to anyone looking for 7mm BR brass.

By Carl J D. on Jun 19, 2020Brass arrived in 50 round plastic boxes well protected.
Checked all cases for neck runout with Century 21 gauge and found all concentric within .0005”. Lubed inside necks with Q-tip and Lee case lube. Expanded necks with K&M expander. No change in concentricity. Sized case necks with L E Wilson FLD for .0015 neck tension. Cases remained concentric within .0005. Seated bullets in 5 cases for test with L E Wilson seating die on K&M arbor press. No change in concentricity with seated bullets.
Using Peterson Brass in 6XC and find it extremely Uniform also.
