i think a marble of some sort fits in a 15mm barrel. i think most barrels for marble fits in a 15 or 16mm barrel. im not fimiliar with millimeters though. i just go by what it says on the pipe.

if its 1/2 inch or 3/4 inch the half inch fits marbles and 3/4 i shoot lincoln logs out of.

basically make the millimeters inches.

I ordered 2000 marbles off ebay cost 40.00usd delivered most of them fit in a 16mm barrel some are alittle big but with some wadding they would work in your 22mm barrel

What are lincoln logs?, I'll just test different ammo and barrels easier than measuring it all

umm.... you dont know what lincoln logs are? well for one they sound like the best ammo. and secondly they are little logs that you can build mini log cabins with and have cowboy and indian wars in. they are extremely fun too.

lead fishing sinkers are devastating... i shot through 3 pieces of 1/2 ply at 150psi with a 5/8 sinker.

Wouldn't it be easier to just use ice?

Of course, one could always just use rocks.

I assume that because those are the numbers you used, you're talking about metric copper.

In which case, your bores are about the following (as recently measured by my brother):
15mm has a 13.5mm bore.
22mm has a 20.2 to 20.4 mm bore
28mm has a 26.4mm bore.

From that, you can start experimenting...
