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.

Weigh a new Lapua 338 case, and the Peterson 338 case. The Peterson cases are thinner, and lighter by 13-20 grains. Not saying Peterson isn’t good, but it’s not the quality of Lapua brass. I’ll spend the extra Money next time for Lapua.

A++ Quality brass

By Layne S. on Feb 12, 2024
This brass is the epitome of quality. Everything from size, to length, the annealing marks were very uniform. .338 Lapua came in a nice plastic cartridge box, which was unexpected. Very much worth the few extra pennies. I will be buying much more from Peterson.

High quality

Very nice brass and packaged with foam ontop so the necks do not get damaged in shipping. Cannot wait to get it loaded up.

The Brass arrived on time in excellent condition. It came in individual cases of 50 in each case. The brass look excellent and after measuring the brass, the measurements were exactly the same as Lapua brass. I am very pleased and will be ordering again. Thank you Graf and Sons, it was a pleasure dealing with you.

Quality brass, wouldn’t use any other

The brass that Peterson brass is very consistent to lapua brass. Holds good neck tension and primer pockets stay solid a lot longer than other companies. I buy Peterson or Lapua brass just because I know they have good quality control. If you ever find one dinged or junk they send you a bunch of brass for free for the screw up. That alone shows a company that cares.

The Peterson brass is very nice have not got a chance to shoot it yet but was packaged very nice and found no problems. The shipping was a little slow but given everything going it was still pretty good will buy more if it shoots as good as it looks.

Great Brass, fast shipping

great Brass

By Lance T. on Nov 27, 2018
so i run two 338 lapua mags
one is an M98 Bravo and one is a Savage BA110 LE stealth
i normally use Lapua brass but most is coming to the end of its life span. i did my research on Peterson Brass and orderd a box thinking ok worth a shot for the price
did some head to head comparison with the lapua brass through both rifles respectively. check concentric measurements and weight fluctuations between brass and only came up with one discrepancy in the Lapua brass but nothing critical.
checked internal volume capacity and came up with basically the same brass as lapua
both performed almost identical in internal volume loading and accuracy out of their own respective rifle
time will tell on life span but as far as i can tell I'm going to save myself $ and switch to peterson brass and will be ordering another 100 casings
definitely would recommend Peterson brass.

338 Lapua Magnum Brass

By Larry R. on Nov 27, 2018
This brass should be considered a work of art! I own an AIXMC .338 and every round worked flawlessly! As noted previously the only thing I found were a few minor length inconsistencies. Concentricity was spot on! Highly recommended!

338 lapua

By John T. on Aug 06, 2018
First off this brass is second to none and it's a little cheaper than Lapua brass. I own a Savage 110ba/le .338 Lapua. All the other brass, Hornady, HSM, S&B, Norma. All of them were to thin, too soft etc. They all got stuck in my chamber after firing. The only way to remove them was using a cleaning rod down the barrel. NONE, of the Petersen brass gave me issues. I can easily lift the bolt with one finger to eject the brass. The only inconsistency was the brass length. It varied from shortest case to longest by .06". Not a problem that the case trimmer didn't solve. Highly Recommended.
