I recently bought a CZ452 Special. It is essentially the Military Trainer, but with a walnut stained birch stock. It is actually pretty nice, someone mistook the wood for walnut and thought I had a Lux. Anyway, I was wondering if anyone owning a Lux or Military Training rifle had a specific ammo they preferred. I am sure that with the length of the barrel, any subsonic match ammo becomes super-sonic. I am actually somewhat interested in seeing how some of the 1400fps high velocity ammunition acts in the rifle. I bet some ammo would actually get around 1500fps. Guess its time to get a chronograph. So what ammo are you guys using, anyone try the 60gr Aguila subsonic?
