    Where to buy Yong Heng?

    How necessary are the water/oil filters like https://www.amazon.com/TUXING-Compressor-4500Psi-Molecular-Separator/dp/B07Q221JFX/ref=psdc_3753811_t1_B07NQ8X9PJ or...

    Where to buy Yong Heng?

    I see that this has been asked before, but I just wanted to get a current vote for where/what vendor to get a legit YH compressor from. The only reason is i've finally saved enough to purchase one and being the cost is, at least for me, significant; i don't want to get hosed. Thanks all!

    10m anyone?

    On rimfirecentral, they host many different shooting competitions/challenges. Its all on the honor system for rule following and such, but it sure looks fun and those who participate in it do seem to enjoy it. Is anything similar hosted here?

    Moly grease.

    I'm not sure how much aluminum is in the various air rifles around, the couple pcp's i have make it seem to be the metal of choice, so this should be of interest/concern to most. Graphite and aluminum do not get along! The two materials will cause galvanic etching/corrosion. That said, I...

    Up Close Look @ the DonnyFL Fat-Boy 2.0 (Multi Caliber LDC)

    A little extra mass is not always a bad thing. I built a super lite 10-22 that is too lite to hold steady. The mass is what your muscles work against and there has to be some or there’s just no resistance. I am hoping to see a few more reviews before I make a decision. Hopefully it works...

    Tuning Air Arms Diabolo Field .22 cal 16 grain - what would be the optimal speed?

    Everything I have read says 800-950 fps. I imagine it depends on your elevation to avoid trans-sonic speeds within that window. ...

    Tuning PP750 low tune

    I finally got back to working on this after nearly a year - things move slowly for me. This pandemic and home life are taking a tole. I have hit a wall and am not sure how to solve it - I think I have an idea or two, but not 100% sure as to the proper route. I have, through regulator and...

    Tuning Talon P on CO2

    Hello all, I was adjusting the power wheel on my Talon P powered off CO2 the other day, and found that as I increased the pre-load from the default setting, I didn't really gain any velocity but my extreme spread got smaller and smaller. I've got to say, I was expecting the velocity to...

    Tuning PP750 Tuning - Help request

    No, all good info. Thank you much for the pointers. A while back I found an exploded diagram of the pistol and ordered o-rings. I have something like 20 complete rebuilds worth of o-rings now. I was going to just replace all the prints, but will definitely inspect that one under the...

    Sweet! What you said verified what i was thinking and filled in a few bits I hadn't thought of. I know a complete disassembly is in order, but it is needed as I lose half a 250 bar fill overnight. thats a lot of pumping for naught! I have seen in another thread that Thane polished his...

    Tuning PP750 Tuning - Help request

    I finally had time a couple nights ago to shoot my PP750 over the chrony and get some data so I can start to tune the pistol for max shot count. I'm shooting 5m at paper in my garage and would like to see how many shots I can get from it. Below are my shots, all in one line. They were done in...

    Tuning PP750 low tune

     Bambuino- below is the shipping list from the O-ring store. After considering the minimum quantity for the different part numbers, I think I ended up with enough for twenty rebuilds. That’s for normal people, for me that’s about 10 after all the screw ups. I think it was right about $40...

    Tuning PP750 - broke the poppet, need the parts

    I’m not 100% on this; but somewhere I read that the regulator in these pistols has about 1 turn for the full range. You may have turned it too much by giving it 1 turn. Hopefully someone smarter with them than I can give advice.

    Tuning PP750 low tune

    I would love to actually know, but my chronograph is giving me troubles in the garage. I haven’t been able to sort the lighting out for it, so may just have to set it up in the driveway. I don’t care for that route though as I live in town and am concerned the neighbors may get crunchy. I...

    Tuning PP750 low tune

    Hello all, a coupes months ago I got my PP750 and love it! But being I only use it for paper at 5m, I would like to tune it down to 350-400fps, and maybe even get a few extra shots out of it. I’m thinking most of this will be accomplished by lowering the regulator set point, correct? I...

    Tuning PP750 mods?

    I am struggling to find two of the required o-rings for a rebuild. The ones i cannot find at www.theoringstore.com are pn49 OD-27mm x 3.1mm CS and pn54 ID-3mm x 1.8mm. All other o-rings were found in NBR 70 Durometer. Really hoping 70 durometer is adequate. Any leads on the two missing? I...
