Murdoc Posted January 16, 2017 Report Share Posted January 16, 2017 Hi! I have seen, somebody made here 3-4 BB shells for "over-fps" CO2 revolver (it shooted over 400 with one BB shell). What about the accuracy? Terribly bad, because all BBs had mach lower and random fps??? What about shooting 10 BBs with one shot with custom HPA gun??? This is just brainstorming after seeing friend's 1/3 shot Umarex fake Walther shotgun... Any comments welcome! Link to post Share on other sites
renegadecow Posted January 16, 2017 Report Share Posted January 16, 2017 I'm assuming Win Guns? They end up patterning like a shotgun which isn't all that bad as the original shoots just as accurately but with one bb at a time and even with a custom hop up installed. The bigger contributing factor to inaccuracy in those are the shoddy aluminum barrel and the rubber tipped shells. Use a brass barrel (even from a stock ACM will do better) and the metal shells and they can be made to group a lot tighter. Link to post Share on other sites
Murdoc Posted January 16, 2017 Author Report Share Posted January 16, 2017 It seems (APS shell ejecting) that my theory is working except I want to store the "gas" in my HPA rig, not in the shell. And I don't want shell ejection... Link to post Share on other sites
renegadecow Posted January 17, 2017 Report Share Posted January 17, 2017 I'm confused. Did you want to make a revolver or a shotgun? Link to post Share on other sites
Murdoc Posted January 17, 2017 Author Report Share Posted January 17, 2017 One shot (but 10 BBs) HPA bolt action shotgun! Similar to Mauser GEHA, or Mossberg 385... We can call it rifle too, if the shell would be less similar to shotgun shell (depends on the construction). Reloading method is quite slow, but would work like a mini grenade laucher with less BBs but much more range, and I could carry many-many shells. 700 nitro express shell would be ideal (it could hold more BBs); the only problem, I don't like the double barrels.

renegadecow Posted January 17, 2017 Report Share Posted January 17, 2017 Without using shells you'll need to use the gas system of Marushin's M500. But even those only hold 5 bbs in line. Link to post Share on other sites
Murdoc Posted January 17, 2017 Author Report Share Posted January 17, 2017 I will use shells anyway, but shells can look like shotgun shells, or like shells in DBoys Kar98K. So you say max 5 BBs... Link to post Share on other sites
renegadecow Posted January 17, 2017 Report Share Posted January 17, 2017 5 if you limit yourself to cannibalizing an M500 system. If you use shells, Apple Airsoft shotshells can be made to hold more (9-10?) as Catgut Violin has done. Another system exists which doesn't use shells and shoots 10-12 bbs at a time by Mad Max (the guy behind AI) but we'll have to wait until it's actually out first. Link to post Share on other sites
Murdoc Posted January 17, 2017 Author Report Share Posted January 17, 2017 I have lathe so won't buy anything, but happy to hear that 10 rounder shells exist and work. Link to post Share on other sites
