Are 300 bar bottles worth the effort?

Jump to latest Follow Reply
Another thing a lot of guys in the north deal with is pressure drops from cold weather. It is a significant change going from filling a tank indoors at 70° odd degrees to an outdoor shooting match or hunting in 40° or below weather. Fill that gun to it's max 300 bar in freezing weather and watch that gauge climb way past that when brought back inside.

Though I rarely fill my 4500psi airguns past 3600-3800psi, the option of being able to fill to 300bar or 4500psi is welcome. Much less opportunity to accidently fill higher than their rating.

I think the attached reservoir/bottle should be sized such that a 250bar or 3600psi fill will give a sufficient number of shots for the intended purpose, even if it's rated for 300bar.

I have two 9l tanks.... Idk anyone who is competing with 22lr that is trying to compete with some tiny scba tanks.

Compete with a different setup if you need to. Nobody is holding you to shooting with a panthera shooting 40g slugs. Shoot lighter slugs.

Has AGN turned into people crying about what they can't afford to do?

Damn dude. Shoot what you have. Enjoy it. If you wanna compete with a certain setup... Work some overtimee and buy it. 🤦

"Is it worth the effort?"...at the level you are at in this sport I would say yes...do what ever it takes, I always heard aggravating tasks referred to as "labors of love" in hobbies/sports, like servicing compressors or working a second job to afford one...lol. Myself...like fishing tournaments...always made a pass time hobby more like a job...competing in shooting contests the same...for me...I would get beat anyway...I crave more shots at lower pressure myself...I have a Styer Pro X .22 on the way...advertised 200 to 140 bar for 65 shots @ 30 fpe...I'll believe it when I see it...hope to bump it down a little to shoot CP domes for more shots/fill as I have a lifetime supply of them (at my age anyway) the name of my game is to have fun...not to make a chore out of it...just sayin'.

No real desire to push my guns that hard, but your answer is an Altaros booster. You can fill your bottles with them using a garage compressor and you can use their portable kit to take your one tank and boost the air fills from it up to 300 bar. The other great thing about boosters over compressors is they do not heat the air anything like a compressor, so there is no big drop of pressure when it cools.

@Centercut - Seems like a lot of people really missed the general point of this. I have thought a lot about this too, even before the 300cc bottle part of the question.

As you mention, it is hard enough just to fill to 300bar and get many fills to that high and see the benefit. I had the same question when considering a 580cc/300bar bottle. How often can I even take advantage of that extra 50bar before I have to again take the tank back to the compressor? Am I getting any advantage?

I think the first few responses really hit it… a portable compressor becomes much more necessary if you really need that 300bar, especially if you only have a 300cc bottle.

The other thing I have noticed on several rifles, is that filling even to 250bar put extra pressure on the reg of the rifle and it didn’t shoot as well filled that high (much higher extreme spreads). Hopefully the rifles are keeping up with the high pressure requirements.

I bring this up because I've been thinking on this for a while, and just filled 7 SCBA tanks yesterday, 3 from 0 to 310 bar, and 4 from 200 to 310 bar. The ones filled from empty are now at about 275 bar due to cooling off, and the ones "topped off" are at about 295 bar. So, let's say I filled to 320-ish, and then set them aside to cool, all 7 of them. Yes, I could go back today and fill them to 310 so that they would have 300 bar-ish when I get to the range or wherever I'm shooting...

OK, now let's look at the new gun(s) that some feel needs 300 bar bottles, or actually will need 300 bar to shoot a match in NRL-22 with the new P. In order to shoot 40 grain .22 caliber slugs at 1050 fps (remember, this is the "revolutionary" thing where the gun performs the same ballistically as the .22 LR subsonic rimfire). I think maybe 12 shots between fills are required for some of the longer stages, correct? So, if the gun (Pursuit of Accuracy video) gets 10 shots from 250 to 190 bar and the reg is at 175 bar with 34 grain slugs at 1040 fps with 250 bar bottle, and a shooter wants to shoot 40 grain at 1050 fps he'll most certainly need a 300-bar bottle. This means he needs to fill to 300 bar between EACH STAGE.

Now stay with me here. Your tank you bring can fill the first fill to 300 bar, since it started at about 300 bar. But what about future fills? How about the 5th or 6th fill (stage)? Certainly not 300 bar, maybe 250 to 260? Now how does the shooter get the shots necessary to complete the stage? Sure, he could bring more than one tank, and cart them around with him, but that's a big PITA. Things that make you go hmmm...

In the usage scenario you describe (NRL-22), an emphatic no for me. Would pack my Tikka T1x, a brick of Lapua, & call it good. And this is from a guy who decided long ago that he prefers air to powder, despite the added expense (& at times, aggravation) of the ancillary equipment HPA requires. Even sold most of my rimfires (the Tikka is all that's left) to partially fund my air arsenal.

For other pursuits- hunting, bench rest etc - no downside to having the 300 bar option. Would want to see a shot count based on 250 bar fill before buying, since I'd rarely (if ever) fill it past that pressure. Some would do so regularly though, so as others have stated, nice to have the option.

Exactly and good points. Yes, quite a few comments either never read the OP or totally missed the point. Thanks for picking up on what I was trying to say…

Whoa... Let me break down the OP...
1. Can the P shoot 40 grain .22 cal. at 1050 fps and get at least 12 shots from 250 bar (factory bottle) fill (.22LR rimfire ballistics - this is the FX advertised performance)?
2. If not, can it do the same with an aftermarket 300 bar bottle?
3. If 300 bar bottle is necessary, can you fill the bottle enough times to 300 bar from a 310 bar SCBA tank to complete an NRL-22 match?
4. If not, what are your options?
Hope that helps, there seems to be some confusion... :unsure:

I'm a 300 bar only guy. I like the extra shot count. I don't use a secondary fill tank. I carry around my compressor and a Honda eu2200, if i feel the need. With 185 to 200 shot count .25 running 25grain pellets or 26 grain slugs running 940fps either way. It's win, win for me.

I was curious and wanted to share, just in case anyone else is thinking of the practicality of dragging a generator from lane to lane at a PRS match.

I'm not a PRS guy, BUT I am a field target guy and dragging 50lbs (gotta have some fuel in there) of generator from ft lane to lane would really suck the fun out of the match for me. And you still got the compressor, and the gun, and other shooting parphernilia to haul......again, call up the Himalayan Porters.

1) It should be able to with a 700mm barrel.
2) assuming 600mm barrel, maybe not. But should be able to with a 300bar bottle.
3) no
4) Options: 700mm barrel - or - a slightly longer bottle - or - dual bottle adapter? Maybe not what you want, but reduced performance is an option - lighter slugs (30-36gr) and/or lower velocity (880-980fps).
