If they are such a good do, get sown in then and buy one. I will be interested to see the improvement in accuracy at 25-30 yards, the improvement in velocity consistency over a ten shot string etc. etc. etc.
I don't think I will be bothering.
Just another thing. Whenever I have been interested enough to have a look at a fired airgun pellet I haven't stood over a bucket. I've shot into a trough of water, or the village beck at around twenty yards at an angle. Amazingly enough you can retrieve the pellets with no deformation at all. But I find it a lot easier to slug the bore.
