TM MWS with HPA drum mag help needed

Recommended Posts

Have come across a bit of a problem with my MWS when I'm running my HPA drum mag.
It's running at just under 50psi, at under the DMR limit of 298 fps on .36s.
BUT it's utter wank.
No range at all. Really slow bolt and poor recoil. No shot to shot consistency in range or accuracy.
It's operating probably 50-60% of the range I get from using mags / red gas.

Here's a link to some vids:

The vid of the lower fps is from the drum mag, whilst the higher is red gas mag (the mags were warm when I did the test, hence the higher fps).
The other vids are so you can hear/see the difference in the bolt/recoil...

 

Can anyone give me a clue as to wtf might be going on? Because I have not got the foggiest!

I'm probably asking the obvious, but does it perform better with higher psi?

I had a we scar that if the psi was too low, the recoil was sloppy and range was bad as there was not enough air to cycle correctly.

Yup, works much better with higher psi- but power goes up and is no longer site legal 😞

 

I think it might be the reg, so @rocketdogbert had kindly lent me his to see if it works any better.
