I made a rule to myself not to own more than 3. One for each caliber. Works good so far. Heck you can only shoot one at a time anyways. I want to get me another one but have to sell one first.
Wow! you have SOME self control! I usually have 8 pcp rifles at a time. Before I beat the ssp addiction, I had 6 of them, and at the end, all six were FWB300 juniors in different generations. I sold all the ssps. I did sell two pcps so now I only have six of them, but that's temporary most likely. One for each caliber? no can do! I have four .22's let's see,
An HW100 FSB .22, two FX Royale .22, one 1st gen with no adjuster or regulator, one newer with both, one Brocock Bantam Sniper HR .22.
In .177, I have a Crosman Challenger 2021, and an Airmaks Katran L.
From my way of thinking, I'm short two .177's
And now, we've come to my one and only rule of buying airguns...... I only do two calibers, .177 and .22. BUT, I have once or twice went for a .20, but it didn't last long with the limited pellet choices, and at the time I had one or two, the pellet shortage was going on which made it even more frustrating, so I'm guessing I won't go there again.
