I usually use Lapua Brass I heard a lot of good reviews about the Peterson so I thought I would give it a shot. So far I have no complaints

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.

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!

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.
