Supporters Sitting Duck Posted May 24, 2015 Supporters Posted May 24, 2015 With regards to cheating chrono I often wondered at the chrono - no mag required hold gun upright - marshall drops in his own 0.20bb the bb would roll down barrel stopping just other side of hop up holding gun at a slight incline to prevent bb rolling forward NOW chrono it - deffo bb is 0.20gms, the hop wouldn't really matter if it was wound right on coz bb stops just in front of hop now Readings should be slightly higher than a gun setup to fire 0.20's with hop on a little but suppose site could allow say 360 - 365 max as their own 0.20 bb was fired with no real hop/spin on it This would also save people who have their hop set just perfect for say 0.30 or 0.25's having to wind it fully off just for chrono As a few sites demand zero hop off I am lead to think Really never saw any joule creep on aeg's like I said - but maybe gas - green gas/propane may expand or behave differently as it propels bb Maybe - and this is just pure bollox maybe when it reaches end of barrel is reacts slightly as it exits the barrel pushing the bb hit the air outside Dunno about CO2 guns - they might also or might not have joule creep Would be interesting to see if the HPA guns have any joule creep as they are using normal compressed dry air - unless they add anything else so in effect what is being expelled is the same stuff an aeg fires so to speak If so then in "theory" if HPA's didn't suffer creep then it would point to the type of gas used in propelling the bb and would point to Gas Guns would only have to watched for creep But yeah end of day the chrono is not 101% perfect but it is a rough basic test to start to ensure we have similar powered guns within the limits of site Still could run a hot gun but that would mainly down to deliberate cheating rather than some gas guns having a bit of creep proffrink 1
