It's about time I treated myself to a new rifle, for a long time I've wanted some kind of Air Arms and some kind of underlever for the collection - not massively keen on the looks of the TX200 but I've always though the Pro Sport was a beautiful rifle.
Definitely going for the walnut stock on this one, but the question is do I go for .177 or .22?

I tend to prefer .177 for its ballistics, but is there a noticeable difference in the firing cycle between the PS in .177 and .22? Is it at all fiddly to load and does caliber make a difference?
I know some springers run much better in .22 and it would be handy to know if the PS is one of them.
