"Smaug"Done? There's no such THING as done. It's only a matter of whether you lose interest to move onto another hobby.
I just bought several airguns after selling an expensive camera rig. Trouble is, air rifles take up a lot more room than a camera lens. I'm overflowing. Need to make some tough choices.
What I do is to have an airgun for each category in which I like to shoot. I find that I'm slowly upgrading over a period of years, until now, I have some pretty high end stuff, that I can't think of upgrading much from here. (for example, one guy in the PCP forum is thinking of buying a Daystate Pulsar, which is arguably the highest of the high end, in sporting airguns. Only dedicated target guns can be more high-end.)
I started with a Chinese springer with a German brand name. Then, I bought a Marauder: quieter, more powerful, and more consistent. It shot great; I was happy with it. But I get tempted by higher end stuff, and replaced it with a Brocock Compatto. Wonderful gun. But I had a couple of iffy kills on bigger pests. HAD to have a .22 PCP. Got the Hammerli. Shoots great and is regulated, but is ugly. Can't I have both? Bought a Air Arms S510. It's beautiful and shoots lights-out accurate at several power levels. It's kind of loud though, at FAC power level. Just ordered a moderator for it. ...and it's not regulated.
Meanwhile, I happened across an offer for a tuned, regulated Kral Puncher Breaker. This one (on paper) has everything. Tuned, regulated, power adjustable, and a Turkish walnut stock. First true bullpup. One of those .22s is going to have to go. Then, maybe I'll invest in a quality scope. Maybe I'll shoot some so much more than others that I'll sell the others?
That's a long-winded way of saying that its an evolutionary process.
