Best BB weight for 450 fps gun (with .2's)

[Neved4eyes]

Hey guys, I play alot of airsoft on private fields where there isn't a large emphasis on fps limits, as long as everyone abides by a 50 foot engagement rule.

My main reason for this thread (and it may possibly be in the wrong category) is to get some information on BB weights. I am trying to achieve maximum accuracy, and hoping to reach out about 150 feet with my gun. All the internals are upgraded to achieve this, but the last issue I'm having is finding the best BB, without having to spend loads of money on every kind of BB trying them all out, and having to sight in my gun every time.

As stated, my gun shoots 450-470 with .2's on average, so I am curious which BB weight would suit the gun best, to accede greater accuracy.

Any input is much appreciated. Thank you!

Deven.

Will give them a try. Thanks alot man, do you know of any calculators that will tell me what my gun will be shooting with .36's? Let me know, Thanks!

Rule of thumb is 0.36g will shoot roughly 100fps below what 0.20g BBs do. Don't focus so much on velocity though, the last few years of my playing I ran my M24 at 395fps w/0.20g, and used only 0.36g Bastards, never before did I have such range and accuracy when shooting at higher velocities. So yes, I was flinging the 0.36g Bastards out at about 300fps.

Its very true, my friends all tend to think that FPS>everything else.... But its funny how a TM VSR10 that shoots 320 FPS out ranges a big l96 that fires 500 fps!

Back to the subject tho, I have used nothing but .36's in my guns, I find that anything lighter doenst do a good job for a B/A

When I had my aeg's set for the 395-400fps mark they really liked shooting 0.30 bb's. I was very consistent 300 with them. The .36 should do you good for 450. I tried my one aeg at that speed and the 0.36 was good. I liked the madbull flavour of the .36's (and most bb's in general)

In my experience .40's perform better than .36's in most situations.

+1 to .36g
You might want to think about going down to 420fps so you can use .30s though, you'll find .36g's are pretty pricey.

Once you have the right BB weight, upgrade your hopup rubber. The single most important part of your gun for achieving maximum range and accuracy is that $10 rubber sleeve.

Like the others, I find that heavier BBs mean lower FPS, but higher accuracy in general.

I use .20s because I can find a steady source but I'd take a bag of .3s over that anyday.

Heavier BB's don't technically affect "FPS" as an airsofter sees it.

FPS in airsoft means more hitting power, Using a heavier BB will make the actual speed that the BB is traveling slower, but the impact energy remains the same.

Wait a minute...I thought FPS meant feet per second...and that defines speed, not hitting power as far as I know...
Isn't the energy measured in joules?

Exactly. And, in fact, heavier BB's will actually mean more energy on GBBs.

Yes, it's measured in joules, just look at it the other way, as Amos explained it, we look for energy retention to get longer ranges and be less affected by wind and air currents, so we focus more on that than the velocity. And the faster the velocity, the higher the spin put on the BB, the greater chance it'll veer off course due to the overhop. Is a balance we try to achieve, which is what sets us apart from the AEG guys, they want the BB to hit as soon as possible so they can get the kill.

I'm talking about in context, not literally.
