For some MilSim's at PRZ they had 400FPS for AEG's using 0.2g.

For HPA and GBBR you had to chrono with a 0.4g BB and shoot under 1.5j.

I don't know why the fuck people are so biased. I know as well as anyone that HPA can joule creep like mad, but so can an AEG.
Someone purpose built a gun as a demo that shot 1.6j on .20s and 3.2j on .45s

Because one in a hundred AEGs creep (not an exact stat), and only with a certain setup you don’t need to have. EVERY HPA unit creeps, and not just with slight effect, but many don’t lose ANY velocity with heavier weight rounds. In fact, some gain velocity once crossing up over a certain weight. So your creep ability is not just there, but always high and easiest to abuse out of every platform. AEGs that creep rarely climb much above the joule standard, just a slow increase per BB weight.

Here’s a real example of HPA creeping:

- HPA unit on 0.20g = 2.26 joules
- HPA unit on 0.40g = 2.69 joules

That’s huge and retarded.


Here’s a real example of AEG creeping:
- AEG unit on 0.20g = 0.95 joules
- AEG unit on 0.40g = 0.97 joules

There’s worse examples, but nothing like HPA or the worst GBBR for that matter.

Swap into the wrong mag, or the temperature goes up and your gun jumps WAY above field limits. That’s without trying to cheat or doing it on purpose.

EVERY gun, when it steps on the field after morning chrono, should be set to handle all BB weights and temperatures without going over the field joule limits. It’s the gun owner’s responsibility to make certain this is the case.

Why bother chronoing AEGs on .20s though?
Its not accurate, and if someone does want to cheat by abusing joule creep then you're asking them to use AEGs.
If you chrono everything on .30s, you only need 1 bag, 1 fps scale, 1 method.
Simplifies everything, and makes it more accurate.

It’s fairly accurate for AEGs, but there’s a lot of HPA users running 0.36 to 0.46 BBs. Also, we’re talking about holding all guns to the same field standards, not cheaters. Someone can still adjust their gun after chrono. That’s a separate issue.
