I have had four Crowns, moving from a MK1 Continuum and a MK1 600. I have migrated to still having two Crowns, but both are MK2s. I have .22 barrels in every length, 380mm, 500mm, 600mm and 700mm. In .25 I have 380mm and 600mm and in .30 I have 700mm barrels.
I agree with pretty much everything that was said by Long_Gun_Dallas and TMH. The 500mm is, for me, the sweet spot in the .22 caliber. The 380 is very very handy and easy to walk and swing, the 700mm is a powerhouse, but the 500 is what stays on my .22 everyday. In the heavier calibers I tend to want “more’ power, and for those I find the 700 or 600 barrels more useful, but then again these are not what I walk around with, but tend to shoot from the bench.
The Continuum is simply a great deal, and when I had only one high end airgun it made too much sense to pass up. Now that I have a bunch with many choices that I can tailor to specific needs its not as compelling, and of course I have all these barrels. If it was my first high end one I would buy it in a heartbeat… wait. I actually did that…
One word of warning though. After buying it and shooting it for a while, I sold my two Marauders and my AirForce Condor SS, and ended up, along with the Crowns, with a couple of Impacts, a Dreamline, and three Semi-Autos. I blame the Continuum.
