[QUOTE="44-40, post: 2834035, member: 126985"] The brass 277 Fury case is a standard 60,000 psi area case, about the same as any brass case. Ya need the bi-metal Stainless steel 6.8X 51 mm military case to get to the 80,000 psi. Of course none of this is recommended by any manufacturer. Interesting developments on about 5 weapons manufacturers working on this new military small arms demand. Some are like "AI" developed "smart rifles" with fully integrated printed circuit electronic rails for attaching "special gear"...and capable of communicating with cell towers and "secure" government servers. Totally different designs and concepts on the horizon, with respect to small arms. The plastic /stainless head cases are interesting. Saint Marks went over 60 propellants to develop the perfect recipe. Many of the big name military contractors involved to get the final contract. Smaller internal case capacity and 10% less powder equals much higher velocities?... They rechambered a Remington 700 for the experiment, before going to the auto and full auto weapons, for the 80,000 psi test! They met the Army requirements at a mere 65,000 psi with a bullpup design and an 18" barrel, and 3000 fps. The plastic small volume plastic/ SS head cases take 20% of the heat out the firing process, converting it to velocity energy. There is no neck on the case it ends at the shoulder, and is loaded with standard military primers. The author was allowed to shoot a 5 shot group that went into .230" at 100 yds with the military auto rifle to be submitted, velocity waa spot on S/D was double digit but not bad. The trigger pull was over 8 lbs! The other information about the rifle is classified...some rumors say the cases can take 100,000 psi. These do not look reloadable...how do ta resize a plastic case with no neck...glue in the bullet? The case has a thick plastic shoulder, it internally tapers down to the bullet, funneling the powder gas to the base of the bullet rather than the internal case shoulder and bullet base in normal case designs. There are at least 4 big name military contractors working on new developments, science and engineering are being pushed to the limits to meet Army's new small arms requirements...with full electronics, integrated battle capable systems and communications available on some. Do a Google search with your rifle! Call home from the battlefield! Checks your vitals, knows the round count and its barrel temperature. A sniper rifle that will not fire when the reticle is off target, just pull the trigger and move the gun, it goes bang when you're on target at 1200 yds ..it hit, with a female reporter who never fired a rifle before ...
