  1. August 28 is also the day that Emmett Till was murdered in Money Mississippi.
    The death of this 14 year old boy from Chicago is thought to represent a tipping point in the struggle for civil rights and the end of Jim Crow laws.
    Yet still the fight goes on. My Father grew up in Birmingham Alabama.
    He told me that it was his military service fighting side by side with men of all colors and religions that made him realize that we all bleed red.
    Rest in Peace Mr. Till.

  2. Slavery still exists in the former empire ,they just didn’t want to be liable for feeding,housing,clothing,medical care for them so they went to arms-length ownership,all profit, no expense.

  5. Re: Schumer say FBI should “sign off” on body armor sales to civilians.

    Get it while you can. With muzzles velocities of 3,100fps, lead core projectiles can defeat level 3. Running M193 out of 20″ barrel might be adequate, if the range is less than 100 meters. AR500 plates, marketed as Level 3+, is resistant. Yet it would not likely be resistant to 300 Win Mag at maximum pressures and speeds, approaching 3,500fps. I’d opt for the standard and less expensive Level 3 protection, as carbine length barrels, by popular demand, are now the standard… It is a good thing that most can’t think beyond ‘the box’. Unfortunately wearing heavy plate would slow this old and slow guy down to a crawl, but it would be good in static position.

  6. A .50 cal can not defeat 3 inch thick steel plates. Design your body armor accordingly. Half inch thick steel will defeat almost any firearm up to just under .50 cal. I know it’s a huge gap but not much caliber from a .300 win mag to .50 cal. Can you still walk and manuver in those plates? Probably not.

    You must do your own research and assess your own athletics.

  7. I have on my desk a piece of ½” cold roll steel with 5 holes in it I shot through it with a 264 Win Mag. High velocity projectiles don’t actually bore (part metal) in thick steel. They literally melt their way through leaving raised craters in and out. 3/8” Some AR500 targets claim to take 300 Win Mag and 338 Lapua Mag but some also state 2900fps max. Velocity counts so range is a large factor.

    1. Speed is the key, not sectional density, or mass. Ballistic coefficient is a factor, yet a minor one. Angle of impact is a key factor. That is why armor is often sloped, or curved. Bullet construction at those speeds is critical. A bonded bullet is probably necessary. A 125 grain will fly faster, yet will it hold together in flight? By my estimates, running a .300 Win Mag, or newer equivalent short mags, or .300 Weatherby, with a 150 grain lead core boolit at 3,400 fps, should penetrate AR500, or Level 3, from as far away as 200 yards. It is going to hurt regardless.

      Per the Army, .50BMG API is effective from a maximum of 400 yards with a perpendicular hit on armor plate, how thick I can’t recall, but Level 4 body armor is certainly irrelevant. Brass Fetch always provides hard data. Here, he steps the game with AP. Although we do not necessarily have AP, the correlation between impact velocity, and depth of penetration is easy to verify:
