Why Test With 0.20 but Recommend 0.25?

I was on Patrol Base looking for a gun to buy. (I did buy one :)) but I came across a common theme on their specifications for the guns I was viewing. So I am not sure how consistent this is with their shop but it brought a question to my mind. Why do they test their guns with 0.20 BBs and give the statistical data on the gun based on this, but then say they recommend a 0.25? Would it not make sense to use what you would recommend? or give the data of both BBs? 

I did try and find this question in the forums but nothing come up so thought ill ask it myself.

Simply because most sites chrono your gun with 0.20g's. However depending on your setup, you'd likely get better performance (accuracy and distance) in the game using a heavier BB.

Inertia basically - historically, .2 was used far more by far more airsofters than now. I got into the sport properly around 2011 and at the time it felt like a 50:50 mix of .2 and .25 being used by people.

 

It's the lowest weight considered usable in airsoft, so it can make sense to chrono at that level, to a degree.

Just how they Chrono your guns normally. It tends to give u a rough FPS figure. But most people tend to play with .25s.

But yea it’s just based off what most sites like to Chrono your gun with. 🙂

Because 0.20g bbs have been the standard for the longest time. They are uber cheap to buy and is seen as the lowest weight possible that is accepted for skirmishing. Idk who rolled it out but before that, 0.12gs were the go to lmao. Back when I started, people were still using 0.12gs. BULLDOG 0.12G THE BEST IN TOWN ONLY FOR 5 SMACKEROONIS WITH A SPECIAL FEATURE WHERE THE BB SHATTERS UPON FIRING WHICH PROVIDES AN INSANE BUCKSHOT EFFECT! BUY NOW!!!!

Appreciate the replies, they all make perfect sense too. I guess there isnt really a wrong answer it. @AK47frizzle full auto buck shot sounds devastating haha

Does most site only allow you to chrono with 1 size BB then? Only asking because the site I played would chrono you for your preferred choice and re chrono if you wanted a change.

 

I have only had the 1 skirmish game so sorry if this is common knowledge.

They tend to be more personal choice now but it’s still the “go to” for Chrono testing. It’s BBs you can just throw away  as mentioned etc. 
I use a mixture of .2s and .25s.

short answer because heavier ammo travels further for the same energy, we chrono on 0.2's because it's traditional and the numbers are what people are familiar with.

 

long answer is here:

 

I never thought they'll travel further to be honest. In my head it's added weight or size to the same internal firing mechanism would have a detrimental effect to the distance the projectile would go. 

 

I'll give your linked post a read though. I have seen some of your posts and comments. You seem to know a fair deal and appreciate your reply

That makes sense, I guess a universal method of testing makes sure no one misunderstands or tries to find grey areas etc.

what weight of ammo to chrono on is a matter of some debate.

 

one side of the argument is that if a site uses 0.2g to chrono all the guns then they know nobody's done the old "it's 0.2g honest guv" routine when they were actually firing say 0.4's.

 

the other side of the argument is that some guns (notably longer barreled gbb's and hpa's) are susceptable to what's known as joule creep, where a gun that's firing fine on 0.2's becomes much hotter only by changing ammo to something heavier. this means even an honest player might think his gun is fine because it passes on 0.2's but the 0.3g ammo he's firing in game is hitting much harder.

it is somewhat counter intuitive, especially to think that a round that's going slower will go further,  that's why i sat down and actually did the math to see if there was a definitive best answer.

@Adolf Hamster your explanation covers it so well in the post. I feel like a lot new airsoft players would gain a ton of knowledge from that (like myself). It also gives you an understanding on what upgrades you will need and how they will affect the gun too as I am not brushed up on upgrades and parts.

 

Feel like I just got a Airsoft + BB degree haha. Thank you

Might be a dumb question to ask as I've not experienced it yet but how does the process work when they test you on site? 

 

Do they give you 0.2g bbs? (if you are using heavier)

Do you normally keep a spare mag empty for it?

Depends on the site, some shove .2's on top of whatevers in your mag (they'll make you fire off a few rounds if its full), others will ask what weight of ammo your using.

To add to what @Adolf Hamster said, depending on the site and who's chrono-ing, and how bothered they are, they might keep a full STANAG and an AK mag at the chrono and get grumpy if you turn up with something less dull. ;)

 

If they're providing the BBs, then you should bring an empty mid-cap to chrono.  If you have a hi-cap, fill it with whatever you're using, but don't wind it up. They'll put BBs into it through the feed tube, then you wind it up.

 

Personally I think pre-game chrono is safety theatre.  It should be provided as a service for those with the sense to use it, but actual chronoing should be done in game, early and often, e.g. at respawn or pulling folk aside entering the safe zone.  Starting with the site owner getting his personal punishment pistol chronoed in front of plenty of witnesses, and work down through the marshals, marshals' mates, regular players, and new-to-the-site players in that order.

@Rogerborg yeah the place I went too, they got everyone to chrono with what they was using. Then random chrono'd 2 or 3 players at the end of each game.

i agree that random spot checks are a good idea, although i've yet to go to a site that actually does them.

The Grange in Coventry is where I witnessed them

Certainly weren't doing that when I played there. Also witnessed a whole load of uni guys sharing a single set of Dan Wesson power down shells for the chrono.

 

Needless to say, I didn't go back.

That is not good. Its no excuse but maybe it's because they only 30 players on the field at the moment that they are doing the random chrono? That's no good though, where do you play now?
