TYLEETESS - I assume you are using an autoloader. Whenever an autoloader jams when using factory ammo, you should normally look to the gun for the problem. Some autos don't handle different size loads well, and the Fiocchi may just be one that your gun doesn't like. One thing you should do is measure the overall length of a loaded shell...sometimes European ammo measures closer to 2 2/3" rather than 2 3/4". You may also want to take apart your gun and give it a thorough cleaning and lube job.

If you do these things and the gun still jams, I would look for a different ammo manufacturer.
