My wish has come true. The shuttle is more than deep enough to handle them with room to spare. I've included a picture of the shuttle with a 17 grain DYNAMIC in the loading groove ready to slide into the shuttle. To use as a single shot, all I do is load a pellet in the shuttle, let go of it and the shuttle slides to the left. Close the bolt and it's ready to shoot. To load the second pellet, I would first chamber pellet number one, and then pull the bolt back a second time. Push the shuttle over and load another pellet, but instead of letting go of the shuttle I continue to hold it to the right and close the bolt. When I let go of the shuttle it slides to the left a bit so the second pellet doesn't fall out. I can then fire the first pellet and as fast as I can cycle the bolt the shuttle moves the second pellet into position to be chambered when the bolt is closed. It takes way longer to explain it than to actually do it. It makes for a pretty neat two shooter. The build quality is typical FX. First class all the way.
I've only fired it a few times in the garage to see how the shuttle mechanism works. The trigger is very nice. I'm going on an airgunning rock chuck, prairie dog safari this summer, and this should make for an excellent rock chuck rifle. Hunting chucks in the high rocky mountains is a low volume kind of hunt. The gun with the leupold 3x9x33mm EFR weighs just under 8 pounds, so even with the digicam mounted it will be just under 9 pounds. Not a bad weight to hump around at ten to eleven thousand feet elevation where some of the best chuck hunting can be found.
Anyway, even if you're not into airguns, most everybody can enjoy looking at a nicely built rifle. Here are a few pics.
