Peterson Long 300 Win Mag Brass
This video reviews Peterson's new 300 Winchester Magnum 'Long' brass, highlighting its potential to improve case life due to a longer base-to-shoulder measurement. The presenter compares it to standard Hornady and Jag brass, noting the Peterson Long brass is closer to the fired dimensions of his rifles' chambers. This suggests less stretching and fewer reloads before potential case head separation, though it comes at a higher price point.
