    I picked up my Bantam Sniper HR .22 today and it had been set-up by AoA with the Huma regulator pressure set at about 150 BAR.

    Do you know if AOA ships gun filled or with just enough air so that they won't risk moisture intrusion?

    That is a lot of good shots… thanks for the information. Keep it coming if you can, my next rig will be a Sniper.

    Bottle pressure was at about 215 BAR (as I recall) when I picked it up in person. And the Huma regulator was set to 150 BAR.

    After about 115 shots, the bottle pressure was down to about 150 BAR and the Huma regulator was no longer filling to 150, but down to about 125 or so.  I did not take note as to what the rifle's bottle pressure was when the Huma regulator pressure was no longer maintaining 150 BAR.

    NOTE: when the Huma regulator dropped down to about 125 BAR, due to the rifle's bottle pressure dropping to 150 BAR, the rifle seemed to be grouping tighter and more consistently with the 15.89 gr pellets.  My thinking is that those pellets may fly more consistently with Huma regulator pressure being at the lower pressure of 125 BAR.  At that point, I also had the power dialed down two clicks from what I call "Power 6" to "Power 4".  At present, I don't have a chrony, so I don't know the pellet velocity.  But my rifle seems to like the 15.89 gr JSB fired at these settings that I mentioned.

    When I refilled the bottle, the gauge on my Omega cylinder (which I believe to be quit accurate) read 240 BAR when the Bantam bottle gauge read about 250 BAR, and the Huma regulator pressure was back up to 150 BAR.  

    It is recommended to re-fill the rifle's bottle s-l-o-w-l-y, so as to not overheat the valve.

    I forgot to mention… I fitted a Huggett Universal moderator (that I had on hand already) to the Bantam Sniper HR .22 when I got home.  It makes a nice difference in keeping the rifle relatively quiet shooting. This moderator looks great on the Bantam and works well.

    No doubt that a DonnyFL moderator (which AoA now stocks and sells!) would perform well also.

    From a 230 BAR fill, 18.1 JSB Exacts, I need to get my tanks filled Gun can be filled to 240 BAR. If I filled to 240 BAR I would see a very consistent 85-90 good shots at this setting.The Huma Regulator does an amazing job at keeping velocity pretty consistent. Shot number 1 @892 , gun was filled and sat overnight, no shots where fired to stabilize regulator like I do with my Crown. If someone wants to do the math and calculate energy, and standard deviation be my guest.

    Shots   1-20    892-882-883-886-886-880-885-881-883-890-883-881-883-880-882-878-881-880-884-881

    Shots  21-40   881-884-879-881-884-878-886-881-887-885-885-882-885-883-880-884-875-876-878-878

    Shots 41-60    884-882-882-884-881-883-881-882-880-880-883-882-879-876-879-877-880-879-877-878

    Shots 61-80    880-883-878-880-877-879-879-883-876-874-878-880-872-873-873-874-871-868-862-865

    bzizzi373… for the above strings, what was the Huma regulator pressure?  And, about where was your hammer tension set at?

    O ring for .22 looks like a 009 size, McMaster Carr has an excellent variety of quality O rings. I use Viton O rings 

    Yes, for Daystate Red Wolf .22 and Brocock Bantam/Sniper .22, the breech seal O-ring size is 5mm x 1.5mm.  And Viton of 75 hardness seems to be the sweet choice for this.  Available from a variety of vendors.

    So I plan on refilling rifle at local paintball shop, but they only fill on Saturday and Sunday. If I'm running low on air, would you say hand pumping is a option? I plan on picking up one one those cheap Chinese compressors in the future, but was wondering if hand pump was even worth it.

    I decided to just take the money I would have spent on a hand pump and apply it toward two Omega air cylinders.  I knew in advance that using the pump would get old REAL fast and that at some future point, it would never be used again and would basically be a wasted $200.

    Hmm I was going to get a cheap Chinese pump for like $60. I was just planing on using it to tie me over until the weekend comes if I fall off reg pressure. Not trying to fill gun with it just to keep it above reg pressure. I've been looking for a relatively affordable way to keep bottle topped off, but with the pressures were dealing with it can get dangerous really quickly. I've seen some cheap chinese carbon bottles on ebay. I figure if they pass hydro they are safe. Not sure if I want to bet my life on it tough lol. I might skip the carbon bottle and go for a quality air compressor, but moisture is still an issue.

    Yes, moisture is definitely an issue that must be attended to.  For $1100 or so (what I paid for my two Omega 100cf and 75 cf air cylinders) you can buy a pretty high quality air compressor. Someday I will take that plunge.  In the meantime, my two air cylinders can carry me quite a long way on a fill-up.

    That's my problem with the carbon fiber bottles is they cost as much as a decent compressor and they still need to be filled my someone. They also need to be hydroed. Not sure of the life expectancy of a $600 compressor,  but the convenience factor is higher than a bottle in my opinion. Anyways I don't want to hijack the thread. I just had some first time pcp rifle user questions.

    Even with a compressor, it's really a great convenience to have at least one decent-sized CF bottle.  Does all of this get to be expensive?  Yep.

    Yeah I've already realized this is quite the expensive hobby, but it's the same as any specialized hobby. For now I think I will just drive to local paintball place, until that gets too annoying then I will decide on compressor or bottle.

    I bit the bullet a long time ago and purchased a Nardi Atlantic 100 compressor, fills bottle to 330 BAR, it was $1800 14 years ago, now they sell for $3195 at Pyramyd Air, this was money well spent, only takes about 10 minutes to fill bottle back up to 4500 PSI. It's a four stage compressor. Keeps all my PCP's filled. No more kissing ass to get my bottles filled Comes with refillable dry pack water/oil separator. Fire dept, Dive Shops, that was enough for me.

    Now that you all have your snipers and have started putting them through thier paces, do you find yourself missing side lever cocking?  I noticed some of the forum members have mention it is a little difficult to cock.  Mind you I've never operated a PCP, so i probably wouldnt know the difference.  I chose the sniper because it seemed to offer so much for a reasonable price.  They only boxes it didnt check was side lever and fully match grade trigger.  I'm very fussy about triggers in rifles, but it seems the sniper has decent trigger adjustment.  Weight isnt so much of an issue but i hate trigger creep.  What so are the trigger and bolt as bad as people make it?  Or are these guys just so used to there redwolf so much that anything esle is inferior?

    I actually like the bolt action, side lever is more compact but the bolt does not bother me. As stated in my other posts everything on this gun is adjustable, my trigger came to me at almost three pounds, I was able to reduce to just under one pound with a slight turn of a 1.5mm allen key. My trigger has zero creep. The bolt will smooth out with use, I lubed my bolt shaft with Moly Paste, I did try several other lubes but moly seemed to work best and stays put, other lubes wipe away, lube sparingly. I got my Moly from Air Rifle Headquarters, I think Macarri moly is some of the best out there. My bolt cycles smooth as silk now.

    Thanks for the info.  I have tools already but do you recomend any other consumables to pick up for air rifles?

    I like the bolt action, that said i have had side levers! Mine is real smooth and the cocking action is perfect do not feel its hard or difficult at all! I to have adjusted the trigger to a nice crisp feel with no creep just a clean break in the second stage.
