Gun Heaven Full Metal Brass Shells for WinGun / Dan Wesson 6mm Series Airsoft Co2 Revolvers - Set of 12

"There is much to like, or even love about these Gun Heaven shells. They are high quality with much eye appeal in terms of realism. Unfortunately, compatibility with revolvers they are supposed to fit in is somewhat of an issue. I own both the Dan Wesson 715 and WinGun G731 which have interchangeable shells. The Gun Heaven shells fit just fine in the WinGun revolver, however, the same cannot be said of the Dan Wesson. The rim of these shells is slightly thicker than the Dan Wesson\WinGun shells, and as a result, the rim rubs against the inner frame of the Dan Wesson revolver causing friction. The quick fix is to file the rims down, but at the price these shells cost, compatibility should come right out of the package.
