Sounds like another dose of 6.8x51 Koolaid. Forget afordable and reloadable ammo.
Forget "cooler burning powders'. Basic law of physics - pressure varies directly with temperature. High pressure means high temperature.
The pressure also has implications for cans. Suppresors essentially work by reducing the high pressure barrel gasses down to a lower pressure exit gas. While internal design affects efficiency, the primary mechanism is volume. This means any cans on a high presure system need to larger than on a low pressure system.
I'm not understanding how a sound suppressor reduces recoil? A muzzle break, yes,but that would be very loud. Am I wrong?
The suppressor reduces recoil from the blast effect similarly to a break. A muzzlebreak spreads that blast out & is very loud as some of that blast is directed backwards towards the shooter, or straight out the sides and top, while the suppressor diffuses the blast inside it's body.
The suppressor or break are most effective when used in very high capacity cases burning a LOT of powder and producing a LOT of muzzle blast which increases recoil.
This is how I understand the phenomenon.
