[QUOTE="RobC, post: 1463071, member: 687"] Bullets that travel through silencers do generally increase in velocity a bit. This is called free bore boost. It happens because the bullet no longer has the friction of the barrel to slow it down but still has the gas pressure behind it. However, the increase in velocity is usually around 50fps or so. This is also with an average silencer length of 7 or so inches and of course varies with how 'tight' a fit the bullet has as it passes through the baffles. With your KX3 there is only one baffle before the gasses can escape around the bullet. It's also less than an inch from the muzzle. I doubt that it would give you a measurable increase in muzzle velocity. You might keep in mind that heat is the enemy of your barrel. You can damage or wear out your barrel prematurely with excessive heat. I wrecked an LMT 10.5 inch, chrome-lined, barrel in less than 7,000 rounds with a silencer and an abusive firing schedule.
