250 vs 300 bottle and shot count

[hunterroark]

I think I must be misunderstanding something. Would a 300 bar (working pressure) 300 cc bottle give you more shots than a 250 bar (working pressure) 300 cc bottle? If I'm correct, Where can I get a 300 bar (working pressure) FX compatible bottle with latest valve?
Your thoughts are welcome. (1st. reg set at 150 bar) .30 M3 Compact.
Thanks,
Hunter Roark

Is my thought process correct? Higher pressure equals more shots?

If your M3 is at 150 bar on the front end and you fill it to 300 bar instead of 250 bar you should have a 50% higher shot count than what you currently have.

Appreciate the input. I was being conservative and estimated 40 % increase because of altitude and temp. variations. I ordered one shortly after seeing your response. The nice thing is being able to switch it between my .30 Maverick and the .30 M3. What ever I feel like hunting with and keeping the 250 bar as a back up.
Thanks again,
Hunter

My m3 .25 500mm 940fps with 300 bar 580cc bottle. I've been getting almost 200 shots per fill. With 250 bar u are looking at 100 to 120 shot, maybe. Huge difference.

That's the same reason I got mine as well.

For what pressure your gun orings are designed for? 250 bar or 300 bar? Shall be some engraving on the action block, and this what warranty the OEM will honour.

Did someone from FX tell you that?

I have a 2+yo MK2, I learned all the tricks with it I can disassemble it with closed eyes. But 250 engraved beside the gauge so I will not challenge that.
Also my compressor is shooting down about 285 (or 4300ish), so I am on a safe side.
And the very last, I am tethering all time BR, with 185 bars.
Just saying.

This is not quite true. You will get a higher shot count, but it will not be the same as the difference in the pressure available (150 compared to 100 Bar). I have long since forgotten the exact law involved (I think it’s Boyles Law) but the bottom line is that you lose a little efficiency going to the higher pressure.

I believe what Big hun is saying.... is just because the bottle is rated for 300 bar doesn't mean the rifle is.

IIRC... my impact had 250 bar stamped on the side. mswp maximum safe working. pressure. Believe it was also in the manual.

Should the valve in the bottle fail...the gun designed for 250 bar would be subjected to 300bar. And out of its designed parameters. And why 250 is stamped on the block.

I understood completely what he said, but you did not read what I posted above. If you disagree with what FX's advertising, I would advise you to call them and ask them why they are selling carbon fiber bottles that would void the warranty of all their current airguns in production.

Alls I saw were 2 styles of carbon fiber bottles for sale.

But not going there bra.

Have a good day.

Impact is all good with 300bar.

300 bar only for 2 regulator guns?

Fx seem to make the new norm as 300 bar fill can only be use on guns with 2 regulators. But im looking at 300 bar guns and I see most only have 1 regulator. Example AEA guns do not have 2 regs and they are fill to 310 bars or 4500 psi. Umarex also makes 300 bar fill guns with single reg. The...

The conservative or safe choice is to assume that if the action is only rated to 250 bar then that is all you should fill it too. Even if you add a reg. you should assume that the reg will fail at some point. Paintball guns usually have a burst disk to protect the action if the reg fails.

Bingo. In the 150cc to 100cc differential question it certainly won’t be 50%. More like 25% if that.

 

[Jlowe]

We're about find out for sure if they ever decide to ship it. I have a 580cc version on my Maverick Sniper, but I don't feel like shooting that long of a shot string just to see. I've been waiting for the 300cc 300bar version to come out.

 

[hunterroark]

After reading everyone's reply and the response I got from FX I cancelled my order at Utah. FX has no plans as of right now of offering a 300 bar bottle.
