Since there is nothing for the drawn string to transfer its momentum to, all the potential energy stored in the string gets dissipated throughout the bow. Dry firing is when the crossbow is drawn and triggered when there’s no arrow in the flight groove. The Barnett Explorer XP 370 is a Soft Lock that protects it from dry firing. To make the package more compact, it has two pieces, but the two pieces can be assembled in 30 seconds with a single bolt (included). The crossbow shoots arrows at a high speed of 370 feet per second (112 meters per second), which makes it a good choice. The Barnett Explorer XP 370 Crossbow is a compound crossbow, and you can bet it has a high draw weight. The package ships with two headhunter arrows, bowstring, lube wax, a Crank Cocking device, a quiver, and a side-mount adapter.īarnett is one of the leading crossbow producers and has been in the business of making crossbows since 1952. Unlike the previous entry, the Barnett TS380 is specially designed for skilled hunters. Hence the aluminum tract further reduces energy lost to friction and makes sure your arrows get as much of the total energy supplied by the bow as possible. This means that aluminum can absorb a lot of heat energy before raising its temperature. This is because aluminum has a high specific heat capacity which makes it pretty hard to heat it. This is where the aluminum track comes in.Īluminum, as you might already know, is often used to make heat sinks in electronics and other high-temperature applications. The hence heated tract may lower the wax’s ability to lower the friction. However, when the arrow rubs against the track, the kinetic energy lost to friction converts into heat. To keep this effect from slowing down the arrows, the arrow tracts are lubed with wax. The worst thing is that the faster the arrow slides, the higher fraction of the momentum it will lose to friction. This results in a force of friction which can significantly eat up the arrow’s momentum.
When you shoot from a crossbow, the entire spine of the arrow rubs against the entire arrow tract. The crossbow has an aluminum track which makes sure the arrow does not lose a lot of momentum due to friction. And Barnett TS380 definitely ticks that box. The bow also has finger safety reminders.Ĭrossbows with high draw weight need to be tough. This is almost a must feature to have in such a high-powered crossbow since dry firing can break the bow limbs in a single instance. The Barnett TS380 also has a soft lock that keeps it from shooting when there’s no arrow.
From Barnett, the TS380 crossbow is a particularly sturdy crossbow that is able to shoot at 380 feet per second (116 meters per second) with amazingly high accuracy.
