BBs and their dimensions..

Postby jonjon87 » Tue Apr 14, 2009 7:49 am

I received my new package from ASGI and was confused after a second. I ordered a bag of C&G BBs .28g and Madbull buckings. I saw that the BBs are not 6mm but 5.95 (+/- .01mm) and thats when the confusion started. After searching on the web, I found some really good info about BBs (manufacture specific) and wanted to share with everyone else. I could not find this info through searching, but if its a double I am really sorry.

I have been using Airsoft Elite BBs for some time which are actuallu 5.95mm, never knew. Here is the link and some excerpts from it.
http://www.lonestarairsoft.com/forums/showthread.php?t=3956

Evike .25: - Smooth and shiny; injection gate was visible; not spherically consistent at all; fairly hard
AVG = 5.909mm
Std. Dev. = 0.0194

KSC .25: - Smooth and shiny; consistent spherically; good hardness
AVG = 5.908
Std. Dev. = 0.0085

Maruzen .3: - Semi-shiny; semi-smooth; can see speckles; somewhat soft
AVG = 5.904
Std. Dev. = 0.0218

Infinity .28: - Smooth and shiny; not consistent spherically; good hardness
AVG = 5.905
Std. Dev. = 0.0114

AE .25: - Smooth and shiny; very consistent spherically; very hard
AVG = 5.95
Std. Dev. = 0.0086

Matrix .2g tracer: - smooth; sinks at the injection gate visible; not consistent spherically; very hard; did not bother measuring these yet because I was annoyed at the sink marks

Matrix .2g whites: - very hard; very inconsistent roundness....saw variance on individual BBs of up to 0.1mm (example: 5.88-5.98mm); shiny; slight surface texture; found a sprue in the bag; one BB had very noticeable sink mark
AVG = 5.919
Std. Dev. = 0.0199

Straight .3 silvers: - Smooth and shiny; fairly consistent spherically
AVG = 5.904
Std. Dev. = 0.015

G&P .28: - Smooth and shiny; not consistent spherically; some noticeable rogue BBs; good hardness
AVG = 5.935
Std. Dev. = 0.019

Toyjet .28: - Smooth and shiny; fairly consistent spherically; good hardness
AVG = 5.895
Std. Dev. = 0.008

Toyjet .3: - Smooth and shiny; speckled; average roundness; a couple rogue smaller BBs; good hardness
AVG = 5.873
Std. Dev. = 0.009

Maruzen Super GrandMaster .29: - Smooth and semi-shiny; exceptional spherical roundness; very consistent size
AVG = 5.931
Std. Dev. = 0.005

Guarder .28: - Very shiny and slight surface roughness; average roundness; seemed slightly softer than other brands; good consistency
AVG = 5.904
Std. Dev. = 0.0086

AE .28: - shiny; smooth; good hardness; good roundness; very large in diameter average
AVG = 5.962
Std. Dev. = 0.0106

Straight .25 tracer: - Smooth and shiny; injection gate was visible; seam lines perceptible; not spherically consistent at all
AVG = 5.906mm
Std. Dev. = 0.0106

Tokyo Marui .3g Precision: - Smooth and shiny; no seamlines, injection marks; very consistent roundness; excellent hardness

AVG = 5.937mm
Std. Dev. = 0.0048

AE .23g: - Smooth and shiny; good average diameter, but varied in roundness; several would measure consistently but then a rogue BB would be mixed in; good hardness
AVG = 5.931mm
Std. Dev. = 0.0136

PHX .28g: - Slight surface roughness detected and shiny; great average diameter and very consistent in size, but they showed some variance in roundness; they were easy to crush compared to others
AVG = 5.952mm
Std. Dev. = 0.0063

ICS .25g: - Surface roughness apparent, but fairly smooth; good average diameter, but they were middle-of-the-pack at best for consistency; good hardness
AVG = 5.935mm
Std. Dev. = 0.0121

KillerBeez .25g eco-friendly (tan): - Smooth, shiny surface; average diameter listed is a bit small because roundness is sketchy but the BBs physically measure on large side which has them chrono on the high side; great hardness
AVG = 5.916
Std. Dev. = .0063

KillerBeez .25g eco-friendly (tan) are middle-to-high of the pack in terms of size, but the roundess compared to some other brands is poor so they cause some accuracy variation in AEGs. Some local players have reported bad feeding and gun jams that were immediately rectified when they stopped using KBeez. They look like an average BB overall. (Neutral)

KillerBeez .25g whites: - Shiny, smooth surface. Pretty good average diameter, but roundness was not good; also variation between BBs was large, as one BB would be 5.94mm while the next would be 5.91mm. Very good hardness.
AVG = 5.929
Std. Dev. = 0.0085

KillerBeez .2g whites: - Very shiny, smooth surface. Large average diameter, but roundness and consistency from BB to BB is fairly poor. One BB would be down at 5.91mm, while next would be 5.96mm. Very good hardness.
AVG = 5.939
Std. Dev. = 0.0137

KillerBeez .28g whites: - Smooth, shiny surface; Middle of the pack average diameter, but consistency from BB to BB is terrible. Roundness was ok. Very good hardness.
AVG = 5.92
Std. Dev. = 0.0159

G&G .28g bio: Fairly smooth, some very light roughness; a bit on the small side for diameter; excellent diameter consistency from BB to BB. Roundness was excellent also. Very brittle as they crack and fragment easily with pliers, but decent hardness.
AVG = 5.909mm
Std. Dev. = 0.0054





Cool eh? Thought he had some pretty nice info. Credit goes to him.

::edit:: added some more and underlined the Brand and added spacing. more readable?

This is great, thanks :D And plz add ICS BBs to your chart if you can get info on them, I think their like 5.99mm exactly, which is perfect in my option. And also, if you can, plz add Golden Ball BBs. :D

I dont have a caliper nor did I make that list. Simply stumbled on it. I may have access to one, but then I dont have those BBs. Perhaps we can find some unlucky soul to send a sample of BBs to. If I can find a caliper good enough (father inlaw may have one - machinist), im game.

I could probably send you some G&G .25 bio's and TSD .20 nonbio's :/

Dono how much it would cost to ship though lol

Should cost the same as a postage stamp. You would just have to wrap them in something to they dont make a hole in an envelope. We are going up to my wife's parents this weekend (airsoft rally up there with friends). I will see what I can get my hands on.

Just think about the difference between a 6.01 and a 6.03 barrel, or a 6.04 and a 6.08

.2mm + is large in terms of airsoft and Cody... jk
