How are you setting up for chrono?

[TheHowitzer]

Just got my first HPA rifle this week and should be taking it out on Sunday

 

Not going to get a chance to fire it before I go so I'm just wondering how you guys would go about setting it up as it's obviously not got the hop set or any of the FCU settings dialled in. I also don't have a ballpark figure as to what the PSI should be on my regulator, I'm guessing it's just going to be a long while trying to dial it all in? 

 

Any tips or tricks? It's a p* jack if that helps

 

Thanks,

Buy yourself a chrono. One of the most underrated pieces of kit for an airsofter to own is their own chrono so they can test things like this at home, especially for HPA users and people who tech their own guns.

 

As you don't have one, what I'd say is set it to about 60psi and take it to the range early on the day, before chronos are set up. Get the hop dialled in, then once it's dialled in and shooting well, take it to chrono and see where it's shooting at. If it's super below 1.1J, adjust the reg a little, but if it's close to a joule I'd say leave it until you have your own chrono and can take as much time as you want fine tuning the reg and FCU, which you will want to do as you'll want to set the dwell and the psi properly to make it as consistent as possible. If you want to fine tune it, you could ask the staff if you can borrow a chrono and sit the first game out, but I wouldn't pester the staff before the games as they'll have their hands full chronoing everyone else. I have my own chrono so I usually take my chrono up to the range, get my m21 set for 1.1J on the money, adjust my scope, make sure the hop is right etc, then I go to chrono for the site once I've done all my own setup with my own chrono.

Chronos should be mandatory kit for HPA users. Why would anyone drop a huge wedge of cash on an HPA setup and not £50-£60 on a chrono is beyond my limited comprehension.

This right here is why I have some sympathy with Anzio's 1J limit on HPA.  Just not their method of conveying that and implementing it.

As impulse said, get a Chrono.

When i got into this sport and started Teching, i knew the first thing i needed was chrono to check my teching.

 

A Polarstar JACK, depending on nozzle would see about 60 to 80 PSI for 345FPS on .20g but there are many factors that can cause you to up to down your PSI.

 

I had a P* JACK in an MP5 and she needed 80PSI.

But my P* Fusion Engine in an M4 only needs 54PSI (red nozzle, red poppet and Lightning Banjo).

 

Point is no one is going to accuse you of running a hot gun if you go, chrono test it at site before anyone else to set it up, then at actual chrono test have it within limits and play at that.

Mr Howitzer, I do not have an answer or suggestion on the air setup, but I know harking on you about a chrono wont help you for Sunday.
