The problem is, I keep running across all these damned guns that look like semi-autos but are actually revolvers, with a revolving pellet/BB cylinder in them and these simply won't do for my purposes. These things seem like a really crappy idea, as it's almost impossible to get a good gas seal on both sides of the rotating cylinder and so you lose a hell of a lot of CO2 with each shot fired. I'm looking for fairly low velocity guns, preferably nothing more than 400fps or so. Any ideas/recommendations?   Posted: Fri Jul 31, 2009 4:16 am AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6929 Location: "Out There" Walther PPK/S (BBs only) is one...   Posted: Fri Jul 31, 2009 5:05 am broommaster2000 Moderator Joined: 10 Mar 2007 Posts: 5714 Location: City of Groningen, Groningen, The Netherlands It's to bad it's limited, but not really strange. With semi-auto, it's almost certain that a lack of accuracy will occur. It's just inviting you to pull the trigger. FX made a semi-auto airgun, but that's a real full size rifle. Because of this system, wear and tear is increased causing failure much earlyer then one would expect. Of course, you also fire a zillion more pellets so technically you "use" it more in the amount of time that you would be firing a manual rifle. Being a rifle you don't feel like putting down doesn't help either. They're so much fun, don't you ever shoot them. You'll want one. These rifles are so darn expensive that they're hardly worth the money. They also consume a great deal of air, because it's not really the best mechanism. Funny fact is that you can automate them. _________________ BIG GAP   Posted: Fri Jul 31, 2009 8:24 am fritz Silver Status Member Joined: 25 Nov 2008 Posts: 2442 Location: New Jersey- outside of Philadelphia That's why it's hard to make a true autoloading airgun. Because of the inefficiency of air. IIRC an English company made an airgun cartridge, it held Xpsi of air and the pellet inside it so that you would not need an airtank in the field. It probably wasn't that powerful, but if it was could easily be made into an autoloading system. IIRC it was VERY expensive, also. _________________ "I never set out to be wierd, it was always everyone else who called me it" -Frank Zappa Speed is impressive, accuracy is deadly.

(what few there are, tend to be quite pricey) it would be my guess that the demand is not really enough to justify manufacturers to design and build them; costs would soar dramatically. keep in mind, right now, the airgun community is not as regulated (read that as "feared") as is the firearm community simply due to the lethality/ability to inflict damage factor...if the airguns become as prominant and efficient (not to mention, powerful) as the current generation of firearms in the semi-auto catagory, there will be more governmental regulation. generally speaking, the single shot is all the average airgunner needs at one given time...you know: "one shot, one hit/kill..." IMO, semi-auto plays more of a role in defensory shooting...full auto, military assault roles. JMO...

That's why I prefer to keep Uncle Sam out of my gun cabinet (or rather house). What he doesn't know won't hurt him. _________________ "I never set out to be wierd, it was always everyone else who called me it" -Frank Zappa Speed is impressive, accuracy is deadly.

LEP revolvers work like that: http://www.co2air.de/wbb2/thread.php?threadid=37572 It's in German, but the pics should tell tales enough. 7.5 Joule, as the German limit wills it (unless one has a permit). I'm not sure if you can get much more power out of it, perhaps with bigger cartridges. I have seen a rifle that used cartridges 3 times the size of the ones on that site. It did pretty well at 30 yards. Also known as "Brocock" cartridges. _________________ BIG GAP   Posted: Fri Jul 31, 2009 3:53 pm Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND Hi Buster, what you need is a SKIF A-3000 28 shot CO2 repeater see: http://www.pyramydair.com/blog/2006/09/anics-skif-a3000-co2-pistol.html It will shoot pellets or BBs the mag holds 28 pellets and is a rotary belt that slides up the butt.

The main reason there are no true autos is the shape of an airgun pellet "Diablo", this makes it very difficult to load from a normal powder burner magazine they are to delicate, I have seen a design that uses a brass tube about 10mm long to hold and protect the pellet, these are spring feed from the magazine and the bolt loads the pellet into the breach, then ejects the tube when loading the next round. This was expensive on brass tubes as they were invariably lost.

I assume they figure kids will be the only ones using them and therefore an impossibly heavy trigger pull decreases the chances of an accidental discharge. And that your finger will get sore after a while so you'll not even want to shoot the gun for long, thus decreasing the odds of an accident. That's why serious aigunners get crosman pistols first, before all else. Because you can easily fix their turd triggers. _________________ I done been assisted by the trees and rivers.

Yo Buster, check out the Crosman C11, its a 18 shot CO2 repeater, true magazine style clip, but its over 400fps , so might be a bit powerful. Price is right too at $35. I had the airsoft one like this and it jammed on soft bb's but this steel .177 version is supposed to work very well. http://www.pyramydair.com/p/crosman-c11-bb-gun.shtml AirCube   Posted: Sun Aug 02, 2009 9:49 pm RatcatcherDino Member Joined: 14 Jul 2009 Posts: 76 What about the Beretta CX4 Storm? ________ S360 Semi-auto CO2     Air Gun Home Forum Index » General Air Gun Questions and Topics You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT - 5 Hours   Page 1 of 1   All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First  Select a forum Main Forums----------------AirGunHome Q&AGeneral Air Gun Questions and TopicsPicture GalleryTarget Shooting: Casual, Fun and CompetitionHunting, Pest Control, Varminting People/Events/Airgun Issue Discussion----------------Introduce YourselfThe BS TopicClubs/Events/Regional/Political Airgun Issues Maintenance, Modification and Reviews----------------RiflesPistolsAntique, Collector and Novelty AirgunsBB GunsPellets/AmmoOpticsAccessoriesAirgun Smithing Buy, Sell or Trade Forums----------------For SaleWant to Buy   Note: If you are seeing "Please enter your username and password to log in."
