How to test weapons in Battlefield 3 without affecting accuracy score?

Do you know of any time when the game is [not] counting the bullets you fire or registering any hits or misses? Would the time when there is this "Waiting for players" message be suitable? The reason I ask these questions is that, as mentioned in the main question in the title, I want to be able to just change weapons, test them out with different setups, suicide the kit character, switch to a different kit or weapon, test again, and rinse and repeat. My best guess is the "Waiting for players" screen, but I'm not 100% sure that firing bullets in the air during that time really doesn't count; I hope so. Can anyone confirm this or give me a different tip to test weapons? Many thanks for anyone taking the time to offer tips or information.

You can play on unranked servers. On unranked servers

• all weapons may be unlocked (depending on server)
• nothing counts towards your stats
• dogtags taken still count

You should be able to test any weapon there.
