Maybe even a .32. My rifle loves them, and it shoots around the 480 mark.

Get a bunch of bbs man and give them a try.

I really love the Bioval .27's. That is what I am going to be running in my TM L96. Great rounds and they are extremely easy to get the hop up set for them.

Thread jack (Sorry!): Can you see them like you can see a white bb when you fire? I have always wondered...

Are you talking about the clears?

Not really, but if the sun is high, sometimes they will look like a little ball of light, but not very noticeable. I'd recommend white bb's so you can see where your darn shots go!

Yes I was. Thanks!
I will never ever buy black BBs again. EVER!

I would go with Woogie's idea, just buy a whole bunch and see what works. (Hell, I might buy the ones you don't like xD)

I was thinking about the bioval .3's.

Biovals are pretty nice.

Have you looked into .29 Super Grand Masters?
