Ballistics and how less power is more energy delivery.
EDcase replied to AirSniper's topic in Off-Topic Discussion
Perhaps I misunderstood your original point but if you're saying less speed equals more energy at the target then you've got something wrong there. -
Ballistics and how less power is more energy delivery.
EDcase replied to AirSniper's topic in Off-Topic Discussion
BBs don't deform on impact so the energy dissipation is not equivalent to hollow point bullet dynamics. Energy dissipation is proportional to projectile cross section area which is why hollow points dump all the energy so quickly. Energy = 1/2mv² Where m=mass and v=velocity Because it doesn't deform the energy dissipation of a BB will not change so lowering v will result in less energy at the target. -
SkyRC and Turnigy are trusted makes of chargers. Stay away from Nuprol Have a look through this thread:

I don't think the video has any relevance to BB ballistics. First off he's using hollow points which don't have an equivalence in airsoft. What he's 'discovering' is the well understood projectile speed vs impact damage trade-off. This is the fundamental dilemma between the two most common military rounds. Slower 7.62 will do more damage to un armoured target but less penetration to armoured ones. Higher speed 5.56 has more penetrating ability for armoured targets but less damage to unarmoured ones. But none of this applies to BBs using the magnus effect. -
Yeah Tim, don't fiddle if it ain't broke. Adding buffers to short stroke is easy enough if you want to do that but its silly to throw money and time at a pistol when you're new to it all. Use it as is for a few games and learn by talking to others. Then you'll have a better idea if you want to upgrade a specific part or buy a new base gun and go from there.

Yeah, that's a good charger (Same one I have) Use 'Balance' charge mode. Hop rubbers may have deteriorated so be prepared to replace those but they're low cost and relatively easy to replace by you or a tech. Fitness is another matter ?
-
Welcome back Simon ? Yeah, if they charge with an intelligent charger they're fine. (What charger have u got?) You can get Lithium Ion (Li-On) batteries now but I haven't used any so duno if they're better. BBs will be fine. (Bios might be an issue so test a few to be sure) Nothin new except airsoft pew pews are much harder and more expensive to get with Brexit and Corona messing up supply. Very few European retailers ship to UK anymore. (Gunfire is the only one I know of that will)
-
Hi and welcome Yep, that will be fine for outdoor and indoor games. (Bit pricy in my opinion) Size doesn't really have as much effect on range unlike real weapons. Of course a longer rifle can shoot further but not always the case as there are many factors involved apart from barrel length. Do lots reading on the forum because most of these things have been discussed.

Absolute Airsoft in Reading. What Is it Like?
EDcase replied to Groot's topic in Skirmish Sites, Stories & Reviews
@furylemon97, try somewhere else to compare. Absolute was actually my first site and got my first UKARA there. I thought it was OK until I tried other places. 'Red Alert' is good nearby and so is Skirmish Wycombe' a bit further. -
That's the first video I've seen of his. I'll be looking through his others ?
-
Essentially it cannot be seen by the public even in your own property. (Actual case of police being called because a person saw a pistol through a house window)
-
Appreciate the thought Oneshotscott ? As said plenty of times in different ways ? FPS vs Joules both rely on correct BB weight being calculated and this is almost impossible to enforce. (Sites can hand out test BBs but time and cost make that very rare) The best thing we can do is make sure the sites you go to actually chrono and encourage random testing through the day. Boycott sites that do not chrono so they get the message.
-
Sorry to hear that gasman. Not the best time of year for it anyway.
-
I think its more of an issue using the players BBs because with both testing methods you can't be sure they tell the correct BB weight. It would be ideal for the site to provide some BBs for testing but the cost and added time at chrono makes it difficult. (I know some sites do it) Anyone who wants to cheat can still do a bit by setting hop to max before chrono anyway.
-
Same thing. Changing an IF to a RIF.
-
You can own a RIF without UKARA if someone gives it to you as a gift. Changing an IF to a RIF by painting it black or changing parts is technically illegal but if used properly for airsoft no one will care. But if its ever spotted by the public and police are called, you'll have some tough explaining to do...

? Is Sam still playing?

DON'T use it with Co2 ? That will end with a catastrophic failure. A pistol has to have a Co2 nozzle valve to function properly and a strong slide to withstand the recoil. Pistols sold with a Co2 mag will be configured for their use. Is THIS the magazine you need? According to THIS, the HFC can use TM, WE, KJW and Taurus mags. Some may be a bit tight but will cycle. I applaud your scruples Maybe keep it for spares. Certain parts may be reusable with other pistols...
-
It does sound like its not filling properly. How did you purge it? Its quite normal for GBBs to vent as they use the last bit of gas when there isn't enough pressure to close the valve. Don't use WD40 except for cleaning things as its more of a de-greasant than lubricant. Take out the valves and soak in silicone oil. Check O-rings and replace if you can. (Spare generic O-ring packs are available) Worst case, you can also try to find a replacement output valve. I think KJW might be compatible but best to check that. Take apart the piston and clean it up. (Its not very difficult) Ragged nozzle indicates it hasn't been feeding well but shouldn't affect actual firing. Check the Hop rubber hasn't been damaged. For everyone I'd advise getting some fill valve O-rings, also known as silent fill O-rings. They fit into the outer fill valve and prevent any leaking while filling. You can find them in airsoft supplies but THESE are the same for a lot less money.
-
Yeah, just enjoy what you've got ? Mid caps are a good compromise between ammo count and cost.
-
I'm using a Lonex BAW (L4-01) which is amazing but unfortunately really hard to find now. Alternatives would be BOLT and TokyoMarui NGRS GBBs do tend to destroy themselves after some time but parts can usually be replaced without much difficulty. Again, TMs tend to be made from better materials that last longer. The downside of GBBRs in games is the expense of magazines and lack of ammo compared to the one-man-army hi-caps.

Not heard of any incidents in airsoft but there are many cases of Li-Po's in other devices catching fire from phones to 'hover' boards. Sometimes while charging and sometimes just being used normally. I've set one off by hammering a nail into a puffy battery to kill it before throwing away. It did actually explode but I think that will only happen with such extreme structural damage. ie shorting all layers at the same time. In most cases its a rather violent chemical fire that builds in intensity as the battery is consumed. It may be very rare for airsoft sized batteries but its not worth taking any risks with something that could end so badly. I use a baking tray because I don't like the idea of a potential build-up of gases in a bag if something goes wrong. My desk is near the charging area so keep an eye on things when charging and have a powder fire extinguisher next to me.
