I think I'll make my own magazine someday, well, a 3D model at least, since I already designed a single-shot tray for various calibers for the RTI Prophet, I might as well make a rotary magazine too, now that I have the dimensions to do so... And by the way, I don't own an RTI Prophet or for that matter any PCP airguns, I only designed the tray for a fellow here on AGN.
So if you guys have any ideas for a magazine design, how it should be in terms of higher capacity (I know, that by making the capacity larger, the magazine is going to get bigger - greater diameter, as well), then I'd be glad to take that into account when designing one.
But as I've said, I'll get to it someday, I've got other things going on at the moment...
