Other than the trigger and pilot it's a fairly standard co-axial muzzleloader. I've had it up to 240 psi with no leaks but more likely I will be plinking with it at 150psi.
Weight: under 5lbs with scope
Materials: ABS reinforced with Kevlar main tube, aluminum .64 cal barrel, pine and plexiglass stock, pultruded fiberglass bar, pvc endplugs (and maybe valve I can't remember), PMFG saddle-blanket (holds main tube to stock via screws), Kydex clips, poplar ramrod, mineral reinforced PET scope mount, brass pins, phenolic trigger, aluminum trigger guard
Power:
marbles @150 psi 630fps 79 ftlb
marbles @240 psi 750fps
.625 steel @240psi 500fps 140 ftlb
This launcher lives in Canada so it is stored with a trigger lock and I have the appropriate license.
I am quite proud of the pilot which is easy to fabricate with primitive tools (saw, file, drill) and operates mechanically so it feels like a real trigger. Also quite happy with the reinforced pressure tube... I happened to have Kevlar and aircraft epoxy laying around
The texture coating is made by painting on Titebond 2 and sprinkling on cork powder, then priming and painting.
I preserved the overall shape of the original stock (I recently shot through that old stock:) but from a design perspective I've moved on.
Too cold for video but I'll get some up soon and hopefully some heavier slugs.
