[QUOTE="swampratt, post: 2503555, member: 15054"] The first link i posted stated this in testing. During the development of the Tango 51, Tac Ops took a standard 26-inch barrel and cut it down to 18 inches in one-inch increments. Between 10 to 20 rounds were fired at each increment. They found that a 20-inch barrel provides for a complete propellant burn and no velocity loss when using Federal Match 168-grain BTHP, a cartridge that has become something of a law enforcement standard. Going to an 18-inch barrel only resulted in a loss of 32 feet per second (fps). I do not shoot very far i mainly plink paper to work up a good deer hunting load. The loads i use now are good for fall turkey season.. can harvest them at 250yards easily. I do not really stretch it's legs..The fast loads i build are not accurate it is happy with 165gr at 2630-2700fps. For longer range shooting i have my 30-06 that will shoot the same bullet 150fps faster. [/QUOTE]
