AT THE RANGE
Exactly how long the wipes will last in the Aurora II goes far beyond the user manual. Supersonic rounds through a short pistol will wear out wipes faster than subsonic through a duty-sized gun. The more powder you have burning and blasting from the muzzle, the shorter the life span.
The original Gemtech Aurora was designed around subsonic Israeli 158-grain ball ammunition. We can confirm this load works very well, as does Freedom Munition 165-grain HUSH. Ammunition with truncated cone projectiles, like a lot of 147-grain on the market, will reduce the life span of the wipes.
Because we wanted to play with extremes, we used supersonic 124-grain NATO ammunition in a tricked out micro-murder Glock 43, and 165-grain HUSH ammunition out of a Glock 17. Differences were night and day. With a 165-grain from a full-size pistol, we were able to unload a full box of 50 before the wipes gave way — from the G43, about 17 rounds.
