I thought it might be useful to have a thread where we can discuss our shared experience of CO2 replica guns. I currently own four and have had mixed results compared to both my expectations based on manufacturers' product descriptions, and Andy's reviews. More often than not I'm shooting them in my cellar at a range of 8m. The temperature is a pretty stable 10 degrees Centigrade. I usually load the CO2, pre-warmed in my trouser pocket, just before shooting and put a dab of silicon oil on the tip of the cartridge. I store the guns empty. I don't yet own a chronograph, but do intend to purchase one at a later date. I'd be interested to know if other members own the same guns and whether or not they've experienced similar levels of performance. My own experience is briefly summarised below... Though before continuing I should tell you that I'm fairly new to this type of gun, my eyesight is far from perfect, and I'm by no means an expert marksman:
Umarex Mini-Uzi .177 BB
I'm generally pleased with the performance of this gun. The one I own is entirely made from plastic, unlike the Swiss Arms version that Andy has reviewed. I'm getting around five clips worth of shots per 12g CO2 cartridge which equates to 140 BB's fired. The accuracy is quite good over 8m and I can hit a 4cm wide x 8cm high target around 8 times out of 10 from a standing position.
ASG 1911 Dan Wesson Valor .177 Pellet
Again, I'm generally pleased with this gun. I'm getting up to 60 shots per 12g CO2 cartridge, though the power is decreasing significantly after about 50 and the last few shots are effectively being lobbed out of the gun barrel. Every so often a pellet gets stuck in the barrel and has to be cleared and occasionally the pellets don't line up properly with the barrel and won't fire. Both problems are mitigated somewhat by taking care over loading the pellets into the the cartridge and making sure they're well seated. The accuracy is pretty good and I can hit 4cm wide x 8cm high targets around 8 times out of 10 from a standing position at 8m. It should be noted that though I love this gun, it doesn't have blowback and is the quietist and least exciting to fire.
Umarex Walther PPK .177 BB
This gun certainly looks the part and feels good in the hand, but I do have some concerns over it's accuracy. I can get up to eight clips or around 120 shots from one 12g CO2 cartridge, but the power levels drop significantly towards the end. I was initially disappointed by the accuracy of the gun, but put it down to having a short barrel and firing BB's. I can't hit a 14cm x 14cm target with it from 8 metres, but can do so consistently from 5 metres. The gun is very low powered and, even with a brand new cartridge, you can almost see the steel BB's flying off in anything other than a straight line. It wasn't until I saw Andy's review for this that I wondered if it might just a problem with the particular gun I purchased. His results on the range were certainly much better than my own and I'd be interested to know how other members have got on with this gun.
Gletcher P08 Luger .177 BB
I love this gun and was very happy with it until recently. It's definitely the most CO2 hungry of the guns I own and I can only get two or three clips from one 12g cartridge. That's around 40 full-power shots and then another 20 indifferent ones. The trigger was very heavy at first and the BB's often didn't feed cleanly, but a bit of oil helped significantly with that. Initially the accuracy was pretty good and I could hit a 4cm wide x 8cm high target from a standing position around 6 or 7 times out of 10 at 8m. I suddenly found it impossible to hit these targets though and couldn't even hit a 14cm x 14cm target without deliberately aiming high. On investigation, I've found that the BB's are now hitting a good hand-span below the point I'm aiming at, at 8m. I can't check the power at the moment, but I'm wondering if it's dropped for some reason. The gun has never been dropped or otherwise knocked about and the only gas seal that I can see easily looks fine. I'd be interested to know what any other members think might be the cause of this problem.
So that's it for now... I hope to start hearing from you soon. Both about the guns I've mentioned above or the various CO2 firearms you own yourselves!
