Can be any size you want! Download HGDT (http://thehalls-in-bfe.com/HGDT/) and have a play aout with the settings in that.

I would go for something around 2L, anything more than that won't give you much increase, but you'll need a nice long barrel to accompany it.

Take a look in the combustion showcase and use the advanced search to have a look at guns other people have made for ideas.

Also, do proof-read your posts after you write them, I somewhat doubt a tennis ball gun needs a 100m chamber, and I think a 65ml barrel is a little small.

Nice to see you are using metric though :)
