Chronoed my rifles yesterday with .20 bbs.

There are charts for reference (not 100% accurate) that will tell you the joules the different weights are running at powerwise but you need to chrono with those weights to check. Saying that some chronos have weight options too.

All but one site I've played make you chrono with their own ammo to stop people loading up to trick the testing. Part of me likes this but part of me doesn't as I don't like putting unknown branded BBs in my rifs but it is what it is and it stops fowl play (sort of). Again there's nothing to stop people tweaking post chono but it's a gentlemens game and if it seems a little off you can always ask a marshal to check. I've never asked a martial to check a players fps but I have in terms of MED that some players flounce.

As most sites are 350 max and the law is 370 fps (full auto) there's room for slight variance (and most sites have a + variance). <DELETED INCORRECT INFO - BRAIN FART DETECTED> Personally I will chrono at home with the weight I intend to use and check it matches the joules of the sites I play. Then I'll chrono with 0.2 and see if it's still within the fps limits the sites state. I do both joules and fps as some do one or the other or both. Sounds a little confusing but it makes sense with a chart but perhaps not in my description :lol:

The law is NOT in FPS, the law is 1.3j which is 374fps with a .20g BB.

AH I stand corrected. Thank you. ? Either way I stay within the limits.  :lol:

wind the hop-up on a quarter turn and you'll probably lose 5fps.

Get a grip, I'm talking about shaving off 1fps, not 20!

To be honest I prefer playing at sites that enforce this practice , you know it’s as close as you can get to a level playing field (bar everyone having to chrono with there hop dialed completely off) at the start of the day .

One would hope they do use quality BBs for chrono .

Indeed, it's about all you can do to safeguard players.

I remember one bloke at a place I used to play when I started laughing to his mate. He'd had his pistol run through the chrono on green gas and then switched to black gas and heavy ammo. Left a huge welt on my melon. I was unaware what he was saying at the time so didn't think much of it (first ever game). Didn't help that the same place also ran a chrono that was 100fps out so people turned up with 450fps pistols etc and got the green light to play. They knew what the score was but went with the moody chrono. Marshals son and his mates where allowed to run riot. Got a DMR to the face at 6m. Same little pleb shot my mates mesh face mask and it was only just stopped by a whisker. Again flouncing the MED.

Never been back there.

EDIT: This place didn't use their own ammo... players discretion.

The site I play at has the below limits

View attachment 42899

I chrono at 295 with 0.25g Bbs in my Predator, and at 315 with the same in my Co2 1911.

All guns are marked with a the wrap if they pass chrono, and there are random checks .

It never occurred to me before,  but should you chrono with the hop set, or backed off?

You should chrono with your hop set to how you will use it in game

That's cool, that makes sense and it's what I do
