Is there a bulk fill CO2 .22 or .25 you know of that would fit my needs?

    Here's the situation I'm in, I like to travel for 2-3 months a year in a travel trailer and since I don't know if I'll end up in States with strict gun laws a powder gun is out.  I would like something that could potentially have some limited use in self defence (can of worms open I know) and while I could see a .25 semi auto PCP having that ability PCP really isn't practical for me with limited space and power so I've let go of this idea.  I do carry a 10 pound bottle of CO2 in the event I need portable air or a tire fill in remote locations so the ability to bulk fill would be ideal and I've accepted that it will just be used for some plinking on lazy days. 

    I was actually pretty dead set on the Diana Chaser as it would be ideal for my needs and space and so on but there doesn't seem to be a bulk fill option.  I really don't want to be spending an additional $25 a year on cartridges. 

    So, any ideas or suggestions?  QB79?  Moding a QB78, Umarex or something else?  I can drill and tap and tig and mig something if needed for sure.  I did talk to Mike shortly today and he said I could us a Xisico Sentry PCP on CO2 if I wanted but I haven't seen anybody doing this. 

    Anyway, I would love any suggestions or ideas you have in response to this fragmented post.  Thanks in advance, I wish I had a more clear headed thought to start with but I rarely do ( :

    You might look at the Air Force platform-there used to be a Co2 option for their guns.

    I think I just figured it out, I have an Umarex Gauntlet already and while I would prefer .22 and it's in .177 all I have to do is screw a 12oz bottle on the front and I'm done.  I guess I thought there was more to it but that's fairly easy and the route I'll go unless you know of a better option.

    ^This is actually a very very clever idea. I have one of the AirForce CO2 adapters kicking around somewhere, and it worked great allowing either the use of CO2 or building at the time was the cheapest regulated gun option possible by attaching a paintball HPA tank. The one fly in that ointment though is that the AirForce guns are all single load/single shot which is not so great for follow-up shots. 

     

    As an aside, check the laws on where you're going, because various airguns aren't legal everywhere either. I'd also add that while an airgun may work as a deterrent, the stopping power of virtually all airguns would be considered very poor by comparison to firearms. We consider "high power big bore airguns" to be over 150 foot pounds, generally speaking. That is less power than some .22LR loads. The self-proclaimed "most powerful production PCP in the wold" the Umarex Hammer is claiming a max of 700 foot pounds. That is just a whisker more than the handgun loads I carry, which I should add handguns are woefully inadequate when it comes to stopping power as well. And the velocities of airguns straight rule out hydraulic shock as well, so (handgun, or airgun) you'll have to hit CNS to drop a target. Even then it is questionable, as I've seen video of a law enforcement officer taking a 9mm round to the head, passing through his brain, and he continues to function. I believe it was ball ammunition, probably at subsonic velocities, but something to keep in mind. 5.56 NATO is considered an inadequately powerful cartridge by many hunters, and there are debates within the military constantly about whether it is sufficiently lethal for their uses as well. (the round was designed with a wounding protocol, the idea being that disabling and wounding enemy soldiers drains more resources than killing them outright) Those rounds are about 1200 foot pounds. .308 is where you finally start getting into real man-killers, and that is just the low-end of performance, and those rounds tend to run 2600 foot pounds. 

    My point in all this? I don't want to tell you how to live your life, however you might want to reconsider the wisdom of carrying an airgun as a self-defense weapon. A really powerful flashlight which you can use to temporarily blind an opponent who is at a distance and run combined with some bear spray/pepper spray/mace/etc (check the laws about which class of what is legal) for someone in a closer-range situation might be a better thing to bet your life on. 

     

    Just my opinion, worth what you paid for it, which is to say nothing. Also don't misconstrue any of this as legal advice, because it is most definitely not that.

    Oh, I'm a powder gun guy by nature with decades of shooting experience in that realm.  You're way over thinking it, for self defence in my situation I'd just take the Mossberg 500 pistol grip pump loaded with buckshot that I currently have sitting next to my bed and call it done.  It's cheap, effective, the sound is a deterrent and unlike a .308 I don't have to worry about 2,000 feet of of backdrop.  

     

    I do agree with you but this isn't a viable option for travel and so there has to be a plan b.  I do think few people would pursue somebody well getting shot with a semi-auto .25 which is delivering roughly the same FPE as a .22 short of sub-sonic but that would depend on the person and situation.  I do know that in a crunch I would choose a BullMaster .25 over a broomstick though.  I've never been in the you're better of with nothing if you can't have optimal camp.  I mean, I carry an LCP in my car for example as a .380 fits my many needs and situations and while none ideally it still works for all. 

     

    Anyway, like I said I've given up on that idea, I just need to find a good fit for my adventures.

    You might go ahead and order a full set of oring and a firing valve. Factory orings may or may not tolerate Co2 well if not replace with proper Co2 rated seals & it should work just fine tho a bit low on power.

     To convert a QB78 you simply replace the end cap.
