crosman bb's: will they work?
 
probably doesn't belong in this section, but i couldn't think of anywhere else to put it...
so i used to have one of those really cheap clear plastic spring guns, and along with it, i bought a pretty large bottle of crosman 6mm bb's (i believe they're .12g's....or .20g's, who knows...doesn't say on the bottle).
i read on some thread a little while ago that in airsoft guns, you should use high-grade bb's, but i was wondering if those crosman bb's would work too? or would they have any negative effects on my gun? and if so, what's the worst that could happen? (i read that they could jam, but that shouldn't be too hard to clear......right?)

and another question...i've read in a few threads that ppl used propane on their stock tm gbb's w/out any damage because of tm's high quality plastic. can anyone verify the validity of this?

thx lots

yeah , of course they will work. The problem is : probably the AEG won't work anymore after using cheap 0,12g. But the BB's themselves , yes.


As for the GBBs , you can use propane for a certain time on plastic slides but it WILL break after a long use. TM slides are more resistant but they probably will break somewhen

high grade BBs are refined to a perfect sub milimeter finish, and are polished, crossmans arent and could damage the barrel, youll also find that with a light .12, your rounds will go anyways but straight.

Also, i can't remember when it was posted, but someone tried running them thru an AEG and they split along the mould. As far as i can remember it not only buggered his hop, but his inner barrel as well as a bunch of other not so nice things. Basically it's not a good idea.

Crossman BBs are .12g and as such as utterly useless in anything but shitty springer pistols (which happens to be what Crossman softair pistols are). You CAN however use them (and in some instances I would recommend it) in multishot shotgun cartridges (Maruzen shot shells) and 40mm grenades; heavier BBs group too tightly, for one, and the limited gas pressure won't send large volumes of BBs very far. So the lighter, wildly innacurate .12g BBs are actually desireable here to get a bit of extra range and a larger shot pattern.

BB-ejecting handgrenades, AP mines, etc can also use from them (they have no barrel, you just want "stuff" to fly out).

As for the plastic slide Q., it depends on many factors. SOME guns, specially the Taiwanese ones, are designed to shoot propane (despite having plastic slides). In fact some of them will not cycle properly on weaker gas. It's not just the quality of the plastic, there's physics involved here; those Taiwanese guns have much stiffer recoil springs, which absorbs the heavier blowback just fine.

Similarly, Japanese guns are designed to operate on lower pressure gas, but upgrade kits are available (stiffer springs etc) that make it possible to use green gas/propane in them.

And just to mess with you a bit more, metal slides CAN also crack; some (especially older ones) are made of pot metal, and aren't any better than plastic when subjected to heavier blowback with weak recoil springs (a perfect example is the old Zeke metal slide for TM Tac Master - don't know if newer models have addressed this).

So if you aren't getting a gun designed for green gas (propane), either stick to blue gas (134a) or make sure you perform your upgrades smartly. (by way of reference, I have a WA 1911 that I shoot Green with, which still has a plastic slide b/c i can't find an adequate metal one for what I want to do, and it's held up fine with an upgraded recoil spring.)

One of our guys put some through a stock TM M4 (no idea why...) Even with the slightest hopup setting, they curved up at nearly a 45 degree angle about 15 ft after leaving the barrel.

So not only will they possible destroy your gun, they aren't combat effective at all. Maybe save them for a springer or for filling an airsoft claymore perhaps.

I once had one of those cheap clearsoft aegs and i tried to use some .20 gram bbs and it actually striped one of the gear beacause they make them as cheap as they can and it just couldnt hold up to any heavier grade.lol

Crosman Premium .20?
 
I was just curious cause I was at the local shop and this caught my eye. now I usualy get my bbs from HK, but today I got them at the department store. they are Crosman Premium .20 gram bbs. so I bought them and checked them out. When I first opened it, there was this gawd awefull smell of plastic poo. but upon further inspection they seemed to be well made, no seems or anything, well pollished. I think the smell is somehting like lube or something. dono if that affects the gun though. let me know what you think for those who used these before.

PEACE!

Crap. Stick to known brands like Bastard that should cost less than what you're paying from HK.

P.K. June 23rd, 2009 00:29

will they be okay to just shoot around in the back yard? or will it have the potentialy blow my gun up? now you scaring me....

surebet June 23rd, 2009 00:33

Check for seams, and idealy, for width mith a micrometer.

Uneven and cheap BBs will eat through your hop-up, barrel and self-esteem.

P.K. June 23rd, 2009 00:53

n seems at all, lol, how do I check MICROMERs? my ruler only goes mm...

surebet June 23rd, 2009 00:56

You need a precision tool.

Suffice to say, ditch them in favor of Bastards or another local brand.

P.K. June 23rd, 2009 01:04

Im itching to SHOTO! NOOO! 5000 rounds and I have a risk of hurting my AEG. :( thanks for the heads up surebet. :D

surebet June 23rd, 2009 01:34

No problem, keep them for grenades and shells. They have their uses, unfortunatly not in guns.
