Home Forums Hunting & Shooting Ask The Gunwriters New Match Grade Brass Case Manufacturer

My friend Mark from Pittsburgh, PA, found out about this company from a Member of the Ambridge Sportsmen's Club. Ordered some .243 Winchester and 6.5 Creedmoor to try out.

Interesting!

Thanks for posting that.

Might need to try some of their 7mm08 brass.......thanks for the heads up!

Thanks for the info, I’ll be ordering some in 6.5 creed

Now for the $64 question: Does anyone have any experience with this stuff?

I like that they've got some with both large and small primer pockets available. The article on the 6 Creedmoor in the 2018 Hodgdon book features a couple of loads with the same charge, but loaded in both types of case (necked down 6.5). One more nit to pick.

UPDATE:

I received my brass order from Peterson Cartridge company. I now notice that they no longer sell through them, but link to Graf & Sons. The cases come in an "MTM style" clear plastic ammo box, individually protected, with a 3M Tarni-Shield Protector vapor paper and foam padding. The 6.5 Creedmoor Large Rifle primer averaged 170.3 grains from 169.4 grs. to 170.7 grs., 1.3 grs difference for 12 cases and were trimmed and nicely chamfered to 1.91" OAL- all of them. There was still evidence of the annealing process left on the cases, as is military brass. Cases literally shone with a golden hue, super clean. They have a lot number on a sticker attached to the box.

I compared these to some Hornady 6.5 Creedmoor brass I bought locally from Fin, Feather and Fur in Boardman, Ohio. The cases averaged
148.6 grains with a spread from 146.5 grs to 149.1 grs., 2.6 grs. difference for 14 cases. The OAL was 1.914"-1.916", I trimmed these to 1.91"

There was a 21.7 grain difference between the Peterson and Hornady brass. The Peterson brass was more consistent and was similarly priced to the Hornady. The Peterson Cartridge Company brass seems to be an excellent value for the money.

How consistent are the neck walls?

I'm actually more concerned about the case neck and even expansion there, and the case neck being concentric with the body than I am with weight.

That's the first cut test for me. If the necks are bad the cartridges won't come out straight, and that affects precision at all distances. Once everything is straight and true, and you're shooting at extended range, then small variations in weight/capacity may start showing up on target.
