Aaarghh! Another problem. .23 gram BB's jamming

Thanks for the in-depth reply, this is all a good read! In regards to the last paragraph, the dry firing is happening even in Semi auto :( I've adjusted my firing style so i'm not "Snatching" the trigger as much and correctly squeezing. Hopefully i'll be getting a bottle of .25's later today so I can see how they work.

There's something else I've just noticed, maybe this is how it's supposed to be? When you fire on semi, the nozzle retracts the whole way, when you fire on full auto it seems to end it's cycle with the nozzle out, not all the time but more often than not. if you switch it then back to semi the first shot doesn't move the nozzle but from the second one it does. Again, I'm new to this so go lightly :)

Well it's good to pass on stuff people passed on to me and the bits i've picked up for myself; paying it forward, etc. but also i'm not a well man so rabbiting online helps take my mind off what would otherwise be a fucking depressing situation :lol: so yeah, you're welcome!

The reason the nozzle behaves like that is because when you pull the trigger on semi the motor only spins long enough for the GB to complete one cycle, no matter how long you hold the trigger down. On full-auto the motor spins until you release the trigger, so it often ends up stopping part way through a cycle, with the nozzle partially, or fully retracted. It stays that way even though the main spring is partially compressed because the anti-reversal latch does what it says, prevents the GB from spinning backwards. Come to think of it, if i ever knew if there's a mechanical reason why that would be bad I can't currently tell you, but electrically spinning the motor backwards generates a current which can damage the windings.

There is one other often forgotten part which we have so far... forgotten :lol: the latch of the mags. I can't think of a reason why it should behave differently for different BB weights, but I can't think of a good reason for this phenomena full stop. It may be worth oiling them (a single drop will more than do it) and giving them a good wiggle. Obviously this catch has to function correctly for BB's to even leave the mag. It's also the case that different mags interface with the hop unit feed tube ever so slightly differently, which may be why the hicap is working. Hey, it's a theory and whilst it only holds slightly more water than a sieve, for the cost of a few drops of oil, it's worth a bash...

Did you try oiling the BB tubes of the midcaps?

Sorry to hear you're in a bad way, believe me when I say you've been a great help with getting this sorted :)

As frustrating as it may be I don't think my new bottle of BB's are going to turn up today so it'll now have to wait till tomorrow. I've used a digital caliper on a couple of those .23's and they reading as 5.92-5.94 mm compared with the .2's that are coming out at 5.88-5.89. I assume all the time it's under 6mm they should be working fine?

I've put a small amount of oil in the tubes, not done the latch though so that's be next :)

Just a quick follow up, I recieved a bottle of Blaster .25's today, I'm pleased to say that this has resolved the issue :) Crazy that I have a duff pot? are there batch numbers on the bottles at all? (I can't see one) as it may help others to know what batch this came from!

 
Where did you buy the 0.23g Blasters from?

 
you get this I'm afraid....

and everybody has different experiences as we all got different guns n stuff + different batches

plus if you are really paranoid - is it better to buy them sealed in bags rather than in bottles

as you could think those bastids refilled jar/tub with Lidl / Kwik-Save cheapo fire damaged stock bb's

it seems to be firing much better so that is what matters in the end I guess

(cheaper to replace some duff bb's that overhaul your gun/barrel etc....)

the bottle is sealed lol so you know when its open. but on skirmish day always put into a bag, I learnt the hard way and found out that in a bottle, as soon as a few are missing you become the easiest target to hear when your run :)

 
Bulldogs are not sealed - blasters yup but many others are not sealed

Some places sell bags that are not crimped or welded/heat sealed and I

have wondered - yeah are they the genuine articles in there or any old

crap you can find to refill empty tubs/bottles

plus there is always the thought of them sourcing stuff from other places

if usual supplier runs low, happens in many things that the original supplier

can change from time to time

but I guess I am a little paranoid sometimes - well most of time

think perhaps for peace of mind I like to buy in sealed bags of 4 or 5k

and kinda think they are what they say they are

One thing I did notice was the smell! The .23's smelled (in the bottle) like melted plastic! Compared to the 3 other bottles I have, the smell is there but they reaked of it! I'm wondering if they've been heat damaged?

 
possibly heat damage, maybe left in the sun/hot store room for months on end because no one buys .23g BBs!

lesson learned though, only buy .25 and above!

 
I honestly don't even know why .23g BBs exist! people buy .20 because they're cheap, I get that, people buy .25 because they're reasonably priced and are more accurate than .20... but .23?! what niche does it fill?

 
Seeing as how every site chrono's on 0.20's it would seem that is the usual expected ammo and my experience in my local sites is that most people seem to use 0.20g BBs.

 
^^ yep at my site the only ammo they sell is .20s . I have a dilemna in that my mate is renting a sniper this weekend, and I think they will give him .20 bbs -_- well all I can do is give him some of my .25s. Never used .30 and above so don't have any of them.

Sites chrono at .20 because it's a known quantity and the marshals only need to remember one number!

I honestly have no idea why anyone uses .20g BBs for anything other than chrono, .25 cost a fraction more and the performance gain to be had is significant.
