Just arrived by UPS tonight, Artemis PP750. Didn't have a chance to shoot it since it was dark already (and raining), hoping to get a chance to fire it off between the raindrops tomorrow and if not the following day. Looking forward to seeing how it compares to the PP700S-A/Mrodair Airmax2 pistol, just have to keep it safe from the thieving cats now 😋

Still waiting on mine from WesBob in Canada( sometime in April due to C-virus) You must have gotten yours from Krale- Have the PP800(Diana Bandit) & really like it for the price.Have my old friend developing a more effecient valve for it. But very accurate & fun to shoot.

Yeah, Krale was where I bought it. Took about 4 days to get here. Should also have an Artemis M30 coming too, just couldn't resist on that one for the sale price. Weather today is cold and raining, so probably wont get to try out the pp750 until tomorrow 😪

It had ended up getting flagged and initially denied when I first tried with our Mastercard, had to go through 10 minutes on the phone (mostly waiting for an operator) and then could go through and complete it. They already shipped out my second order for the M30, estimated for Thursday delivery  🤩 

The weather managed to break around 1PM today and actually was getting sunny so figured I'd go out and clean out the barrel and get it charged up. The barrel was definitely a lot cleaner cut than my airmax2 had been, good clean crown and aside from needing cleaning everything was nice and smooth and shiny inside after a brush scrubbing and some patches. Unfortunately, as soon as I charged it with pressure from the pump it had a most definite leak in it that was emptying out the cylinder pretty quick. Ended up having to just about completely dismantle the entire pistol before finding the culprit: the poppet valve between the hammer and regular had snapped (looks like some kind of hard but brittle nylon or something screwy). Thankfully we have a pretty good machine shop setup so I was able to just make a new one from some Delrin rod I had laying about. Got that machined out and back in, took advantage of the disassembly to degrease the internals (which was almost none to speak of this time compared to the airmax2 that was gobbed full of it) and get all the orings lubricated with some silicone divers grease and the various sears and slides with some moly grease. Got it all reassembled and it's now holding air like a champ.

So far I have some likes and dislikes with this pistol compared to the airmax2/pp700S-A. This one is easier in many regards to get disassembled to access all the internals, the shroud and built in LDC actually works pretty darn good (especially compared to dry firing it without the shroud/baffles in), the handle is great on it, and the side cocking lever (once moly-greased) is nice and smooth.

It was also pretty clever how they have the sliding rail piece over the shroud, which should be very importantly noted that you NEED that rail piece to align the front iron sight should you ever dismantle the shroud to access the barrel and whatnot (basically the two angled ends will notch into each other and more or less bring the iron sight back up to true vertical while you screw the end cap back on to firm it into place).

For cleaning the barrel I did end having to remove the whole thing since I didn't have a .22 cleaning rod to use in place of my pull through, so that was a bit of a negative there (but that'll be remedied in a few days). I also need to work on the magazine clip, that thing seems to be pretty poorly designed. Tried following the directions and it goes from either loosening the screw holding the clear plastic face plate on and having it slide out or when trying to fill from the second pellet on in the front tightening said screw as you slide the cover and not allowing you to turn it anymore. That'll be for another day of fiddling around.

You would also be pretty hard pressed to use the iron sights with the extending butt, works fine with a scope and high mount rails as pictured (provided your scope had a shorter field of view, that one there I need forwards about 4-5 inches more unfortunately so can't use it with the rifle butt).

Final little diddy of the day was running some quick shots through it at 25 yards using crossman premier domed (.22), 5 shots. Will get out the chrony and fiddle with the hammer spring some and see if that can't get cleaned up a little more when it's not blowing like a banshee and colder than a witch's areola.

So weather was finally nice today and got to do a bit more with the Artemis pp-750. Did figure out what was wrong with the magazine tray, ended up having a grub screw on the back side that needed to be tightened against the phillips head screw on the front to keep it the screw set in place. That being said you still have to be a little careful and cock the lever slowly otherwise the pistol probe had a bad tendency of catching and/or jamming the pellets and mangling the skirts.

The regulator seems to work pretty good (a nice improvement over my airmax2 that didn't have a working regular when I got it), although the first shot after a refill does seem to shoot high and left (which wasn't much different than the airmax2 pistol with the exception that the first 2 shots were usually dubious on mine). My chrony seemed to periodically jump around 130 fps for some shot strings which I think was just the lighting conditions since the pellets were keeping well grouped, so keep that in mind with some of the numbers. I did adjust the hammer spring about as loose as it was physically possible to get without removing material from the back of the handle (I'd be tempted to try a shorter/weaker hammer spring over removing metal at this point). Will try increasing the hammer spring tension another day and see how that plays out.

For not having any better grade pellets on hand than CP domed ultra mag I can't complain too much. I expect it will continue to improve as it gets more shots run through it, so far I've only run about 75 through. The chrony didn't catch the first two shots until I readjusted the position some. From the looks of things I'm getting around 28-30 shots per fill before it starts dropping off the regulator steadily.

Got a better chance to play around with the hammer spring today. It was surprising how little effect it had on the FPS between cranking it as far out as it could go and turning it quite a ways in, but had a fairly significant amount of impact on the accuracy. When it arrived the hammer spring adjustment screw on the back of the gun was pretty much flush, at that point you could turn it roughly a full turn and maybe a quarter back out and quite a few turns further in. It seemed to reach about the peak accuracy 3/8 of a turn past flush even, and would start opening up more in either direction past it. At this point I'm leaving at the most accurate setting, it will more than meet my needs (see bull 1 and 6 which were closely set to one another).

The trigger also had a fairly impressive range of pull strength available through the adjustment screw, down to an extremely light feather trigger to a fairly hard beefy pull with the grub screw further out.

Here's the chrony strings (some inaccuracies again as I was losing light from midway on). All were at 25 yards again using Crosman Premier Domed Ultra Magnum 14.3gr, and these all used the 7 round magazine tray. The + and - values are the number of turns past where the screw is flush even with the stock/handle/receiver.

Only other things I might do at some point would be to go in and debur/smooth the various edges around the air passages and ports to see if that helps clean up the shots a little more. Other than that I've been pretty pleased with how that little pistol has been doing (even with cheaper ammo).

The next little project will be fiddling with the new arrival: the Artemis M30 (and hoping that it takes air without having to disassemble and repair it lol). More on that in a new thread for another day.

@alex-from-upstate-ny. If you have not already check out Giles from the airgun show from England on teardown and clean repair of the m30

Thanks, he definitely tore that down more fully than I have so far, but he also had a lot more problems than I had with mine (everything pretty much was in good working order aside from the bolt being a bit gritty to draw back). I haven't had the heart to take out the regulator yet since they're usually a PITA to get all back together in working order again. Did get all the bolt and trigger assembly apart and greased up. His video definitely would have helped with the locktite notes for one of the screws holding the bolt, found that out the hard way later on down the line 🤐 

Other than that just waiting on a scope to arrive to see how tightly it can really group, 50 yards with a see all open sight isn't the best indicator since I usually don't do better than 2-4" groups with open/iron sights. Do have it whipping out 14.3gr pellets at around 940 fps currently though, don't think it can get a lot more than that without getting a beefier spring for it.

@alex-from-upstate-ny. Thank you for great report on pp 750. Been waiting for that. Will be my next purchase when they come in. Have the 700 , for the money a great little gun, although the stock  is crap. Also have the m11 which is a holy terror. No need for a 22lr any more . Reaches out and touches them at long range. Thanks again for your write up and looking forward for more.
