Unlikely to disappoint - Artemis CP400

Unlikely to disappoint - Artemis CP400

I was a late starter to CO2, being somewhat obsessed with FT competition shooting, but the more I have dipped my toe into this exciting world, the more I have come to appreciate what it has to offer. In short - I get it! Just insert a small 12-gram CO2 capsule inside the gun’s chassis, and you’re good to go for many shots, requiring minimal effort for the duration. Another huge benefit is the lack of weight since CO2 airguns are free from heavy internals like the mainspring and piston found in ‘springers’.

Simple design
Throw in the fast-fire repeater aspect, and it should come as no surprise that this sector of the airgun market has well and truly exploded in popularity in the last couple of decades. On test here is the Artemis CP400 pistol, which is a joint venture between Shaoxing Snowpeak Airguns in China and Sportsmarketing (SMK) in the UK, and it all comes well presented in a smart padded box.
The Artemis CP400 is a semi-automatic magazine-fed design, and alongside the pistol itself, we get three rotary-style magazines, spare seals, an instruction booklet, and two spare snap-on grip tools.
First impressions are definitely favourable, and with the entire chassis, including the integral trigger guard, being an all-metal construction, the resultant 1.5 lbs of mass feels good in the hand. The moulded grips are nice and dense, and it all just feels very solid.
The design is actually refreshingly simple, and whilst we can’t expect too much in terms of performance, given the vagaries of CO2, there’s no doubt everything needed is here for some good clean fun.

Grip removal
One 12-gram CO2 capsule powers this pistol, and as is so often the case, the capsule is housed inside the grip. To gain access, first unscrew and remove the tension bolt at the base of the grip. The moulded grip can now be slid down and off, to reveal the CO2 chamber. Insert a new capsule into the chamber and use the tension bolt/tool that we removed earlier to apply pressure to the capsule via the screw at the bottom. This will pierce the capsule. Replace the grip and screw back the retaining bolt. On test, I then pulled the trigger just to check that CO2 was feeding through, and it wasn’t initially, so I needed to tension that bottom bolt a bit harder to pierce the capsule. No problem, but checking you have power before trying to launch any pellets always makes sense with CO2 hardware.

Rotary club
The CP400’s semi-auto system relies on a plastic rotary magazine, of which there are two supplied. The mag is accessed by pulling the ambidextrous spring-loaded mag retaining catch (just above the trigger) to the left. The mag then pulls straight out. Pellets are simply pushed into each chamber, but all I would say here is that several pellet brands were loose in the mag, so be aware of this until the mag is returned to its slot. I initially searched for pellets that would be tighter, but replacing the mag then felt tight in its slot, and the skirts of the pellets were slightly flattened in situ. Therefore, the pellets need to fit flush so that the mag is free to rotate unhindered, and it’s worth noting that once the mag is in position, the design ensures the pellets are prevented from falling out.

Power & performance
With a few exceptions, it’s rarely worth getting too worked up about consistency with CO2-powered guns since the emphasis is on the fun element, and on test here, I put a few shots over the chronograph, just to get a rough idea of velocity and energy at the outset. Using 7.5-grain pellets, the power band started at 405 fps, and this equates to 2.7 ft/lbs of energy. Thereafter, I kept a record of how many 8-shot magazines I had emptied, to get some idea of the shot count, whilst gauging accuracy over my 10 yard range.
The CP400 comes with non-adjustable open sights, and they offer a pretty good sight picture. I stuck with these during the test, but for the record, there is also a small run of dovetail rail on either side of the magazine slot, so a small red dot sight or similar could be utilized, if deemed necessary. On test, groups of 1.75” were encouraging, and that sort of accuracy means a tin can alley speed shoot is definitely on the cards. I shot with deliberate aiming, then faster to get the shots off quickly, and the results were much the same. The shot cycle is free from kick, as you would expect, and it’s also pretty quiet, which is an indicator of an efficient valve that’s not wasting gas.
The trigger is half decent too and whilst we aren’t talking ultra refinement here, pulling through the shot, and taking up the initial creep, leaves a very reasonable point of release, par for the course, and all very usable. If you hadn’t noticed, there’s also a manual push-button safety set into the trigger blade, and whilst this seems a weird and slightly unsafe place for it, it’s there if you feel the need.
Now back to the shot count. Well, I couldn’t quite believe it, but only after 23 mags did the impact point start to print downwards at 10 yards, which equates to an astonishing 184 usable shots. That’s pretty amazing from a 12-gram CO2 capsule, and well above average for this style of pistol.

Verdict
So yes, you could say I was impressed by the Artemis CP400, as it is simple, straightforward, wholly satisfying to shoot, and unlikely to disappoint. 
Thanks to Range & Country Shooting Supplies in Sleaford, Lincs., for the kind loan of this pistol.
