Home Forums Hunting & Shooting Long Range Hunting Petersen Brass

I use a fair amount of Lapua for a reference comparison. Last year, I was looking for .300 Win Mag brass and found some Peterson in stock, so gave it a try.

Consistency is at least equal to Lapua.

Bottom line, it is excellent quality.

One nice point on .300 Win Mag in particular is they offer a “long” version of .300 Win Mag, which is 0.010” longer to the datum line. So, the “long” brass tends to fit .300 WM chambers tighter than other .300 Win Mag brass, close to starting off with fire formed brass.
