From Wikipedia. I found this info very interesting:

Quote

6mm pellet weights and their usage

0.11 g - Manufactured by HFC, same use as .12 gram. Uncommon.

0.12 g - Used by all low grade weapons such as some spring pistols (which can use .20) and mini electrics. High velocity and low stability. Not to be used in high end AEGs such as Tokyo Marui and Classic Army. These pellets usually have a small air pocket in them.

0.15 g - Same uses as 0.12 g. Uncommon. Not to be used in high end Automatic Electric Guns (A.E.G.s) such as Tokyo Marui and Classic Army

0.16 g - Essentially the same as the 0.15 g pellets. Very uncommon.

0.20 g - Standard weight for most weapons. AEGs use these or slightly heavier pellets. These pellets are usually white.

0.22 g - Apparently no longer in production. Used to be available from KWC and Western Arms.

0.23 g - Heavier pellets for AEGs. Blends speed of 0.20 g with range and accuracy of 0.25 g. Made popular by Tsunami Airsoft

0.24 g - An oddity. Only known manufacturers are Airstrike (a subsidiary of Daisy) and Crosman

0.25 g - Heaviest weight for standard AEGs, blowback and spring guns. Tokyo Marui standard AEG, gas, and spring guns are set at the factory for 0.25 gram BBs, and they usually include a package of 200 of these with the gun.

0.28 g - For upgraded AEGs or sniper rifles. Significantly cheaper than 0.30 g but yields similar performance

0.29 g - Maruzen Super Grandmaster BBs, designed for their Air Precision Shooting series of guns. One of the most precisely ground and accurate BBs available but cost more than other alternatives.

0.30 g - Standard weight for most sniper rifles. Western Arms pellets for their gas blowback pistol series. Uncommon.

0.32 g - Also standard for sniper rifles. Offer best balance of velocity and stability for most spring and gas sniper rifles.

0.36 g - Heavier pellets for sniper rifles. Very slow but have high stability.

0.40 g - Heavy pellets for airsoft sniper rifles. Mad Bull is a known producer. Even slower than 0.36g but even more stable and maintains kinetic energy better.

0.43 g - For the highest level of upgrades in spring and gas sniper rifles. Usually graphite coated.

0.88 g - Possibly the heaviest type of BB available. Usually made of steel and comes with a polished finish. Rarely used and often hard to find.

So in our pistols it's looking like 0.20 gram or 0.25 gram. Why might we choose one or the other, I wonder?

And accumulate practice to improve that ability. Consolidate, build strength where you feel weakness. We cannot raise our ability until we accept our current limitations. Practice dissolves limitations. Matches simply define where the current limits exist. The game of shooting is all about redefining our limits.

The .25g pellet, like the 147gr bullet, might help reduce some of the snappy recoil.

:unsure:
The truth is that there is no choice between the two. You line the sights up in the A-zone and let it fly at the absolute soonest moment that you see what your experience tells you will put the hole where you're aiming it using the amount of trigger control you need to keep the gun lined up in that spot. There is no concern about accuracy or speed - either one is an illusion from behind the gun. There's "where do I want to hit" and "is the gun lined up there or not"... followed up with "did the sights lift from where I wanted to hit". To assign an "either/or" to the equation is to deny the fact that the gun can be shot ridiculously fast while shooting all As - but it won't be done while you're determined that one must be sacrificed for the other - and it also has the amusing side effect of pressuring the shooter to ignore "the shooting" in the name of "the speed" - XRe

I have been told if you shoot outside get the heaviest ones you can find. Just alittle wind will take them off course. That little bit of weight helps some, not much but some.

0.20s get to the movers and swingers faster. 0.25s knock down plastic bowling pins and aluminum poppers better. :)

Is there any harm in using the .12g in a gas blow back? I'm new to the air soft thing, and I bought some .20g with my guns, but was given a bunch of the cheap .12g.

Other than less accuracy, will using them harm the guns in any way?

Thanks

Joel

The .12g are normally hollow and are prone to breaking. This leads to jams, and jams with airsoft guns are not as easy to clear as a regular gun. .12g almost always have seams, too. This also leads to jamming.

Interesting indeed. ;) I'm using the .23g right now and find them noticeably more stable than the .20g.
I'll be using .25g next.

Very interesting. I had heard that you wanted to stay away from cheap pellets because their seams could lead to failures to feed and interfere with hopup thus degrading accuracy, but I had no idea that "cheap, poorly feeding, inaccurate pellets" and "12 grain pellets" were synonyms. Thanks for the info.

The manual that came with my gas gun says in comical broken english to not use 0.12 g pellets. I can get 0.20 gram pellets fairly cheap at local sporting good stores but I've never seen any heavier. I'd like to try 0.25 gram but would have to mail order them.

I tried some of the cheap .12 grams out of my TM 5.1 and my WE 1911 MEU. My 7 year old was shooting some of Drazy's small scale poppers at 5 yards. He was hitting about 1 in 4, which, I thought was fine for him. I then switched to some .20g that I got from Evike. He was then hitting 5 out of 6. I tried these and got about the same results. I don't know if the .12 POI was that far off from the .20, or if they were curving irratically or what. Need to shoot some paper to see if the POI changed that much, but do like the .20 a lot better, regardless.

Thanks

Joel

I use .25 seamless they are pretty stable but anything round like that is going to curve pretty quick. The faster it goes the longer it may fly straight but the sharper it will curve after it slows. Also the shorter the barrel the more likely it is to curve sooner. My hicappa curves after 3 or 4m inside with propane
