Re: Lost River\'s J36 terminal performance?

Bubbas,when a conventional jacketed lead bullet gets pushed forward by the chamber pressure,it actually conforms,or gets swagged into the bore causing an exact fit.the lead is soft enough to allow this.a solid copper bullet on the other hand is not soft enough to do this.it will not expand to fit the bore and gases not only escape around them,usually they are escaping from one area at the muzzle as the bullet exits.if your bore diameter fits the diameter of the bullet perfectly,they will probably shoot very well.this is why barnes came out with the triple shock. the grooves are actually smaller than the groove dia of the barrels but the bands will fit almost any barrel as long as it's close to what it's supposed to be.the grooves also allow someplace for the copper to go as the bullet is engraving in the rifling.
