    Air Venturi Regulator Creep

    Thanks... I haven't Chrono'ed the first after letting it settle (since this tune). I have done it several times before. Even though the reg would read that crept up 2900, the first shot velocity was always a little less. Off the top of my head, I think only 20 fps at the most. It's...

    Air Venturi Regulator Creep

    Hello Again.... I just thought I'd report... I repeated the same 1st shot process a couple more times now with the same result. The first shot is dead on. It's really got me wondering. The crept up reg pressure on the first is 2900. After that shot, things really equalize and settle on...

    Air Venturi Regulator Creep

    Ok ... I found some time to cut a few loose. I put it on the bag, pinch bag in rear. Same I used to zero. (I really need to get a proper setup as you described in the last, but for now....). The reg was sitting at it's usual overnight creep of 2800-2900. Fill was 3500. I had filled it...

    Air Venturi Regulator Creep

    I see what you're saying. I'm sure you're right; I'm fixating on the gauge. I'll target the first shots and see how they land. I'll have to wait till morning but that's my next move. Do you shoot from a bipod much? When zeroing I was on sandbags, all was tight. I put on this $40 Bipod...

    Air Venturi Regulator Creep

    THANKS !!! I'll try that later today. The only problem I can foresee is the overnight reg creep. It always likes to settle at 28-2900 and stay there. I usually dump 2 dry and it finds it's home (2500). Yesterday it stayed almost spot on (2500) thru 4 full strings/fills. My last morning...

    Air Venturi Regulator Creep

    ...Chrono. I'm guessing this means I could back off pressure but for now I left it. Took 2x then adjusted. I moved in 1/2 turn increments. *The 'knee' wasn't nearly as obvious as it sounded to be. I am using a cheap Chrono but it seems consistent. I ran it up nearly 3 turns to...

    Budget Scope AO Scale/Adjustment

    Thanks for the info, just not sure I understand. My understanding of "Paralax" by definition is when the reticle and target image are not on the same final plane. So, if they're in different planes moving your head/vision changes the angle you're looking thru the 2 separate points/planes...

    Budget Scope AO Scale/Adjustment

    Thanks... Game changer is putting it mildly. How I went 54 years completely unaware blows my mind 😂. Especially for the price, I love this rifle. I really enjoy learning it all. The only problem is now I've only just broken this in and I'm already thinking what I want next. 😆

    Budget Scope AO Scale/Adjustment

    My understanding is that magnification change doesn't create any more/less parallax error but whatever error there is becomes more obvious. This definitely means sense as I was siting with minimal and when I went to my max of 10 is where I noticed it.

    Budget Scope AO Scale/Adjustment

    Hello All, I'm still pretty green around here so forgive me. My first PCP I got the A.V. Avenger Bullpup (2), 25 cal. I got a budget CVLife 2-10x32 AO. It's compact, illuminated, came with a nice cantelever mount. It's seemed to always hold well. My question is regarding the parallax...

    Hello Lefties

    Thanks for this... Like I mentioned, I absolutely love this rifle. When the reg failed AV was incredible with tech support and then only 2 weeks turnaround. They did offer to send the reg but the gun was so new I preferred they do it. I'm not really so much wanting to move on from this...

    Hello Lefties

    Thank You !!! That's good to know about the Maverick. That was actually one of my short list "Next" guns. I'm very new. I got the A.V. Avenger Bullpup (2) 25 caliber as my first. I love it. From the bench there are no issues really. Otherwise, I guess the safety is awkward but otherwise...

    Hello Lefties

    Hello to all the lefties out there. I just had a few thoughts and questions. I have always been VERY left handed and even moreso extremely left eye dominant. I'm always pointing out to my wife the many ways this world is right handed. When it comes to shooting, this presents many...

    Air Venturi Regulator Creep

    Well guys here again ... While reading more about tuning, I ran across another method. Basically it suggested selecting a desired velocity, max out the hammer, find the regular pressure that corresponds, then dial back the hammer 5%. Soon as this rain let's up I'm going to revisit the...

    Air Venturi Regulator Creep

    Ok ... I have at least a little data to get started. I plan to go thru the tuning procedure next but thought I'd verify what's going on now. You guys were 100% right. Even though the reg creeped up overnight to 2800+ (Fill: 3800), the velocity of the first shot was less. 1: 918.8 2...

    Air Venturi Regulator Creep

    Wow, ok... More than I bargained for. I should point out this is a 25 cal. At the moment, it's shooting 25.39 gr JSB at 910-920 fps. (I have a follow-up post coming about that). So, I'm pushing 45+ ft-lbs . So far I've taken 4 of them. 3 prior to reg failure and one recently. The first I...

    Air Venturi Regulator Creep

    Thank You... I do have one question. Could there be a situation where the velocity (even at this 5% less than max level) is faster than the max velocity the particular pellet maintains stability? I've read too fast they can 'keyhole' or tumble at high velocity? Can the rifling effect...

    Air Venturi Regulator Creep

    Follow-up question (first of several I'm sure 😊): You mentioned ideal being Hammer spring set so velocity is 3-5% less than the max for that regulator pressure setting. While that makes perfect sense to me: Where is that data available? or is this something I calculate based on...

    Air Venturi Regulator Creep

    THANKS A TON GUYS !!! It's allot to swallow. I plan on sitting down in the next day or two and give this a try. I really appreciate it and will report back.. Thanks again

    Air Venturi Regulator Creep

    Hello, thanks for asking, I can use all the advice I can get .. So I'm shooting the Avenger Bullpup (Gen 2) 25 caliber, Barrel 22.75" I'm targeting the raccoon invasion on my chicken coop. My position is at apx 30-35 yards for the best angle and at least some concealment. I put out a brick...
