[QUOTE="Stormrider, post: 270023, member: 6072"] QuickLoad says the Benchmark is giving you 3479 f/s with pressures at 61,415 psi. SAMMI spec is 55,000 psi. 25.5 N133 is 3523 f/s at 64,625 psi. Both loads are hotter than I'd feel comfortable with. Though if I had a 5.56mm chamber I'd be happier since the pressure limit for that is 62,366 psi but the cases also are thicker... [/QUOTE]
