Sniper Pew Pew

[HimmelChef]

Guys, in your experience what would you say is a safe zone for spring power(fps ranges) for game play rules and such. From what i have been reading seems that there are rules stating, 400-500 fps range, with a .2g and there is a certain range that your allowed. and do most games out here allow .3g for sniper rounds? because i am loving the accuracy i get with it.  Sorry if this is a repeat thread but i figure i drop it in here, tried to search but didn't find what i was looking for.

You must follow the rules that the field and organizer set out.

Most of the time you can use whatever bb weight you want, but you must chrono with a 0.2g bb.

Your FPS will go down with a higher weight bb proportionally so that the energy imparted to the shot is the same.

Thanks, okay thats what i was thinking, it varies based on the event coordinators.  
So by chrono-ing at a say 500+ and the range is 450-500 for spring with a .2g, but if i state that im using .3g then it should be fair enough right?(knowing that the fps does drop with larger weight bb, but not sure how drastic it can fluctuate) or would i have to swap out my spring or change mods to where im making the regulated fps range with a .2g?
Im not sure what mine is chrono-ing at atm, i just upgraded a bit based on reviews and what people seem to like to use as a setup mod list. but my guess with a .2g im with in a 475-500+ range. but with the .3g idk.

Saying a gun must shoot at a certain muzzle velocity is kind of miss leading. The reason guns are chrono'd with 0.20 is because we are using it to calculate the energy out put of your gun. A gun shooting 500fps with 0.20g BBs has a much higher energy output then a gun shooting 400fps with 0.20g BBs. Simply changing the weight of your BB only slows the muzzle velocity but the energy output is the same. It is the energy output that causes harm to people so consequently it must be regulated. So to answer your question, you would have to change your spring out to bring down the energy output of your gun.

I realize i could have just said you have to change the spring but i thought it would be a good idea to explain why this must happen so you may answer future questions about this your self. Hope this helps!

You have to change the spring in your gun so that with a 0.2g bb it will meet the fps limits. Do not change it back after that, or the fps will be higher than is allowed.

A 0.2g bb at 400fps would approximate a 0.3g bb at 327fps.

so... if you pass at 400fps with a 0.3g bb it would be the same as if you were shooting 490fps with a 0.2g bb, which is far above the limit (if the limit is 400fps).

The energy has to be the same.

get it?

BUT, a lot of organizers have special provisions for spring guns, as was asked about, where they can shoot hotter with a minimum engagement distance. Just make sure you know what the gun is shooting, and make sure it's below the limit specified by the game organizer.

This is what i was looking for. so to determine energy of the projectile from my weapon, the .2g is used to gauge via chrono.. Got it!
And how to correctly fix and help meet the standards, simple spring swap is usually good enough.

This is the other one, do they always give a engagement distance? even after you have already chrono'd in?

Great! You guys answered it! lol    Now i get it fully. thanks all!

The engagement distance is usually set before game play and is not adjusted after you chrono.

There is no gradient of engagement distances based on your fps.

FYI you should know what fps you gun shoots at in general. Most games have similar fps rules so if you plan on fielding your gun, get it to fit in those rules and leave it alone. The gearbox has a chrono that you can use for free.

Yeah thats my goal, seeing that most people/skirms/games are sitting around the 400-450 ranges for springers so. thats what i'm heading towards, just need to play around with the chrono a tad.

A. I have no idea what this is supposed to mean. I'm sure it makes sense, but I'm not interpreting it right.

B. Most game organizers, if they have provisions for higher FPS guns over the normal full-auto rules do have different minimum engagement distances for different fps ranges.

i.e. 25-foot MED for AEGs under 400fps, 50 or 75 foot MED for single-shot over 400fps but under 600fps, no MED for pistols.

sorry, what i mean is that from what i have read and seen from most sites about skirmishes/games played, the rules usually state that spring rifles(snipers) usually have to fall into the 400 to 450 range of fps. and now i'm trying to gather and figure out if i should keep in the 150 spring in instead of the 170, to keep that range of fps with the .2g's. because from the forums for the spring snipers, the 170 with my list of upgrades atm(listed below), shoots high 400's and a bit into 500 fps' with a .2g.

laylax:
spring guard, 150 spring*, 170 spring*, damper cylinder head, teflon cylinder, zero trig w/ HP piston, 6.03 barrel 303mm
* and no im not using both springs, just a list of parts that i have atm for my gun.

as far as the engagement distance i'm asking from a snipers POV, and trying to get a feel on how i'm going to have to play. never really been to a real skirm/game, usually just hop in the desert with friends and shoot out.

@ Ganef - do you mean the shop in Tempe named Gearbox?

[axisofoil]

FPS, gotcha.

Honestly... the whole idea of a sniper for a newer player is a bad idea to begin with... for exactly that reason, as well as a couple more. You don't know how to judge that distance, and it's a much harder role to play in the first place... well, different at least, maybe not harder to some people.

On AA, the FPS limits seem to be somewhat lower, but they're not all the games in the area. If you're worried about FPS limits for everything... then stay under 400. If you want games with higher allowances for Sniper category weapons, check out TAC (http://www.tucsonairsoftcoalition.com/forum)

And, I don't know about what parts will get you to what FPS, but it sounds like you've done quite a bit of research into that. Props to you on that mark.

Yes, Gearbox in Tempe will be able to chrono your gun for you.

[HimmelChef]

Well, I gather what your saying about judging distance, but i have been and still working on that, as well as adjusting for weather ailments. I have been reading/watching vids heavily and studying lots on the role and what actions to do as a role of the sniper class.

I used to play with an AUG (don't remember info on it) back in the day, when we had neighborhood teams, and would do urban. kinda go sick of offensive assault, i like the concealment and snap a kill with no idea where it came from as well as relaying info for the players/team via com's.

I have checked out TAC. The do have a higher rate, but i would like to get into something closer to phx.

I will have to stop by that shop this weekend then and see what info they gather, maybe pop a vid for all. idk.  I have to see what range i will fall in. then i guess will have to pick loc's to play.

As for Upgrading your spring to a 170. I would not advise that.(most sites will but a 170 spring at 580-600 FPS) It would put your FPS far above the 450 standard (not that all games are 450 for springs) I would suggest a 140 or a 150 spring that would keep you well in that range. I have an AEG DMR(marksmen) that i am going to put in mine but it will be allowed because i will be disabiling the full auto on it so that it will be in the same class as a spring powered. As for a chrono i'm not sure what it will be at. but as was said the gearbox will chrono it for you

AEGs fps ranges for spring numbers are different iirc.
for example, I have an AEG shooting 470-480 w/.20's with a 130.
