BB Weight/FPS Range Comparison
 

Ok, so here's the deal. I want to spice up the sting of my rifle a bit just by using .25gg BB's. But I really value my range. This is my question, requires only a simple answer.

If I fire a .20gg BB at 400 fps, and from the same gun fire a .25gg BB, will the range be comparable?

Range will be better in most situations with the .25. Heavier weight means more stable trajectory, less effect by wind and brush, etc... You should try bringing a number of different BB weights to the next game you play, and see for yourself which works best with your gun and playing style.

Have fun.

Ditto, 0.25g are by far the best performance BBs out there. I've tried 0.30g BBs in my MP5 and the results weren't that impressive (BUT, using them in my G19 extends my accurate range to past 100ft) but with my MP5 shooting around 370fps w/0.20, I can still get kills out to 150ft easily.

I wouldn't say use them for more sting, I'd say use them for better brush cutting (as Harley said) and for wind resistance and more accurate long range shots. BUT, add in that they hit harder, eliminating a good chunk of people not noticing they got hit. And they make a louder sound too, so you can yell them out if they pretend they didn't get hit.

After I upgraded my MP5, during a game my cousin was under a tree, prone, behind a thin chunk of dead grass. He was about 50ft away. Took me a locap and a half of 0.20g BBs to get a couple to go through to make him call hit. After that I went for 0.25g, that same scenario I could more than likely fire a quick 4-5 round burst, and each one of them would have gotten through.

In the end, just realise that it depends on what you mean by range. Range can be where the BB ends up on the ground, regardless of the path it took to get there, or range as in how far you can get BBs onto a guy. 0.20g will more likely end up farther away, but reduce the effective kill range by being less accurate past 120ft.

I use .25's in my G&G R5 with great sucess now.

Anyone run with .28's? Wondering how much of a difference it will make in accuracy.

In my experiences, it makes shit all of a difference. We are talking about things that weigh less than some feathers. I have used .2's and .25's and found no difference accept for the fact that I got 750 more .2's for wither the same price or 5 bucks cheaper. I know all of the scientific comparisons look good on screen but when you actually get out there and play, you'll find it makes no difference.

The effects of wind and the environment are pretty harsh on things that weigh in the .xx gram area. Is .05 grams going to make much of a difference up against a 20 km/h gust wind or a leaf that is potentially several mm thick? I don't think so.

The only place I found them to make a difference was inside the gun where they are effected by equal force. .25's lower your speed and the way I hear it, things that move and hit their target faster, stay on course much better. I preffer to get more FPS because in the end, things that make impact harder seem to hurt more so people notice it. I grant it will be slightly, ever so slightly less effective through gear though.

I think all the differences people talk about are more just...well, perhaps a comfort factor for believing something gives an edge. No offence though. Again this is just me talkin'. Mabey some of you truley do get better results with .25. Only way to find out is to load up mags with either and test them without knowing which is which.

As for me, I'll stick for getting more for what I pay for. .25's either comming in packs of less or costing 5 bucks more kind of a rip off anyway.

Guarder bottles and bags are the same price for the same count of .2, .25 and .28.

Intresting. You only get 2500 though for how much?

I think AE are still the best value. Plus they have those sweet black bb's.

I find there is a big difference in accuracy between 0.2g and 0.25 g at as little as 50-60 feet. So i am not too sure where or when you have tested or compared the two because there is a big difference. And 500BBs less for the same price is not that big of a deal, well to me anyway.

This is what I use to help calculate for different weight BBs, or can even be used for different size BBs (8mm) for that matter.

Rumplefelt can say what he likes, but I got the experience of running both in my guns, and the 0.25g wins hands down for reasons I already stated. 0.20g sucks ass, 0.25g are much better. Yes, small weight difference, but good performance upgrade. I'd rather use 3-10 of the heavier BBs to accomplish what would take twice as much with the lighter ones.

Now, if the comparison was the difference between 0.12g and 0.20g.................. this:

then 0.12g would be your ideal ammo. :confused:

Thanks for the help everyone. I'll get some .25's this weekend and try them out.

Just remember: Don't buy Black BB's from the get go.. It makes it VERY hard to set your hopup right :D (Not to mention, people will think your mags are empty)

And I second the fact that the difference between .20 and .25 is astounding. After a while, .20's just go ass-wild and spin every which way (with and without hopup), whereas I find .25's a nice decent long range round..

If you're using something short ranged like a MP5K or a pistol, then by all means: Buy in bulk with .20's.. But if you're planning to hit something at distance; stick with .25's.

.20 for indoors, .25 (maybe .28/.30?) for outdoors.

I would assume so. However that it may just get alot worse if you go even lighter. But the fact remains, noone makes GOOD QUALITY .12's but if they did I'd be trying them out.

But hey whatever floats your boat. I know what works for me so that's all that matters to me in this circumstance.
