What's the chance of this thread not smelling of vomit, spilt lager (which smells different to unspilt lager of course) and BO at the end of the day?

The global nature of this forum probably means it's drinking time for at least one member at any one time, and Crawlhomedrunk o'clock for someone else.

I broke it two times with a pneumatic. (BB piston rifle, at 330 psi. 0.12 grams projectile.)

Btw, what kinda noise do you get when shooting it at 6x mix? and, did you get to test it under chrony?

That's quite a claim - have you a topic link to evidence of that?

I am currently working on a MEGA high pressure cannon (well, thinkng about) that fires those RAP4 airfin darts. It will also be hammer valve actuated....

i feel like i should be able to get the speed of sound out of that. either that or ill just modify an airforce condor to 6mm. not sure how but it would kick.

The noise when fired at 6x with a light projectile (2 grams) is somewhat similar to a small rim-fire rifle, it makes your ears ring like for about 3 hours.
It feels so cool firing it because it is hand held.
I would love to chrony this but that will have to wait until i have access to one.

For Ragnarok, i don't have evidences of what i say. You can only trust me or not. But i can give you details, both how i did it, and how i observed i did it.
The gun was the pneumatic piston rifle, 6mm bore, 60cm barrel. pressure was 330 psi, projectile, 6mm airsoft BB (0.12 gram). GGDT predicted an initial velocity of 363 m/s, but the audio recording i id at the time showed approx. 390 m/s when taking every factor into account. Now i don't ask you to believe me, if someone was to come and claim that, i'd be sceptical. but i hope you know i'm not a liar, and i personaly see no ultimate goal in breaking the sound barrier.
