"Hot" under the collar?? Hardly.. I'm not afraid of people of who disagree with me either. I do chuckle at people who continue to believe myths when science says otherwise.Getting so hot under the collar is a sure sign that you're afraid of people who disagree with you. If there are facts, please state them. Federal and the CMP are better advice for me than a free one on the internet.
Lowest milsurp port pressure is ~8350psi
Highest milsurp port pressure is ~10900psi
FGMM is ~9200psi
Your PPU and S&B "garand safe " ammo...are both over 10000psi...
So "garand safe" ammo is harder on the system than FGMM is.
