Yes throw away those fandangle bb's, I would sugest that you downlad a description of parts from one of the threads on this forum, the parts list shows actualline up of components and this may help you disasemble the drozd or give you the courage. I have never experienced jamming and have always used steel bb's, You mentioned roll-outs, you still have a problem as this is not normal behavior, At a glance from what you have said I think that either the barrel is loose or has moved or there may be something wrong with the timing / hitting power of the striker on the selunoid, Before we get carried away try replacement of the cells and dont use cheap ones ( Youll regret it in the long run ) I have seen when kickin out a few hundred rounds with cheap cells that every 5-6 hit of the striker the cell causes power loss because of exteded usage over single fire rate or 3 burst and this causes the striker to hit softer which then ends up pushing a smaller amount of Co2 through the mag - hence a wimpy roll-out! Try the N-size cell repplacement Mod before you progress to see if this cures that iratable problem. Oh- and you realy dont have to cut the selunoids cabled just unsolder from the selunoid! simple! Another hint is to retain the origional tightness of the barrel- Simply wrap a thick piece of leater round the big end piece and use some plyers with a curve in them ( Not straight nose ) to tighten to the max. Good luck padawan and may the force be with you! If u want to disasemble I will walk u through it just let me know. Simpatheticaly NEo45 | ||||

Forgot about this thread.
Changed to steel and no more jamming even if I run all the way to the end of a powerlet. Have had one roll out of the barrel on a few occassions, usually if I am running a 6 round burst and cut it in the middle. Still not as irritating as a jam. Threw out some expensive copper plated lead bbs. JustJim | ||||

Thanks all, ran out of time today, didn't even make it to the store for steel bbs. Will post again after I have a few minutes to try the things you suggested.
Really appreciate the help, JustJim | ||||

You might want to make sure the retaining collar on the end of the barrel is screwed back down tight also. This holds the pistol grip and forestock together tightly, though it shouldn't make a difference. HHMmmmmm .... interesting.

Okay. If you didn't actually unscrew the barrel then the washer is where it's supposed to be. I'd say it's coincidence that the problem so closely followed disassembly.

While driving around it ocurred to me that while I took the retaining nut off the front of the barrel, I never unscrewed the barrel (still don't know how I would grab it to unscrew it).
Maybe I didn't see the washer because I didn't get that far into the disassembly? So, is it even possible that I lost the washer? | ||||

I chickened out before I got the barrel out. Unscrewed it from the front and seperated the forestock from the pistol grip by an inch or two. Removed the cover on the solenoid just to get a look at it, and then decided that I really didn't want to cut the wires since I didn't have any connectors available, and put everything back together.
I may have incorrectly determined that I needed to take the forestock apart in some way to get the barrel out. I'm at the office now, but am going home to grab it so I can have it in front of me. I wasn't expecting such immediate assistance...THANKS JustJim | ||||

Also, that washer can't fall out unless you remove the magazine and the barrel at the same time. If you did that I'll pretty much guarantee the washer fell out.

There is a thin black oversized washer between the end of the barrel that goes inside the gun and the receiver in the gun that the barrel screws into. When you took your barrel out, did you just unscrew it from the front and take it out, or did you disassemble the forestock from the pistol grip?

No idea, didn't ever see a washer.
If I didn't lose the washer, where exactly would I find it during disassembly? I'll try taking it apart again tonight and see if I can find it. JustJim | ||||

People have done different things to solve the problem of the BB not lining up properly in the Mag. Personally, I used a little bit of JB Weld to fill up the gap in the "roof" of the clip. Now, when the BB hit's the top of the mag, it's lined up to shoot straight out of the exit hole on the mag. Some people have drilled a hole through the top of the mag and inserted a nail to stop the top BB. Way to much trouble for me. Using JB Qwik, I was easily able to solve the problem with little effort or time. And it WORKS PERFECT. It also helped up the fps a little since there was less resistance coming out of the clip.
Hope that helps And Swedish Dwarf is right. Make sure you didn't lose the wierd looking washer between the barrel and receiver inside the gun. | ||||

Although you should switch to steel, the way you decribe the timing of the problem makes me think you've got something put together wrong. Did you lose the washer when you had the barrel out?

Yes, the top bb in the clip needs to be pushed down quite a bit to exit the clip, and the bbs at the bottom do seem pretty badly abused. OK, I'm moving to steel.
I don't have a chrono, has anyone worked on a penetration standard for BBs? Something like: All tests performed 24" from muzzle to target. bb standard=Daisy premium Target = Campbells soup can (empty) held rigidly (screw it to a board) no penetration - less than 200fps single side full penetration - 300fps both sides full penetration - 550fps | ||||

They are deforming due to the nature of the gun and the way it works. Every time the solenoid strikes the power head, it blasts a BB out the barrel. Take a close look at your clip. You will see the top BB doesn't quite line up with the output hole in the top of the clip. As the BB is forced out of the magazine and into the barrel, it pushes down on the rest of the BB's in the clip. After 20 or more shots, the BB's in the bottom of the clip have been pounded enough that they really start to deform. The more powerful the blast coming out of the powerhead, the more pressure put on the BB's still left in the mag. Yes, after time, using steel BB's will start to wear on the inside edge of the barrel, but that is to be expected. IT IS THE NATURE OF THE GUN. It is a very simple procedure to remove the barrel, cut off the offending portion and rethread the barrel. Better yet, make your own longer barrel or buy one and you will increase your power by up to 250fps or so. This will really mess up lead BB's. When my Drozd was brand new and stock, it would shoot lead, no problem. But after switching to HPA, doing a full auto mod, solenoid adjustment, N size battery upgrade and putting on an 18 inch barrel, I'm now getting over 700 fps. A VERY NASTY little piece of machinery now!

I've considered that since the jamming seems to be caused at least in part by deformation of the soft bb, but if it is deforming because it is slamming into something inside the Drozd as it is pushed into the barrel, then won't using steel just cause more wear? Or perhaps the steel bb will jam in the narrow spot rather than deform as the lead does.
Even so, I'll pick up some up today and give it a try. Thanks | ||||

Quit using lead and start using Daisy Premium Steel BB's. The silver ones.

I've been lurking for a couple months and really enjoying the conversations. Have a single Drozd, got the all black version. No Mods yet but have emailed JimC about a barrel and bulk adaptor.
I've put maybe 2000 BBs through the thing, and have used only copper plated lead 4.5mm pellets. Initially had no problems, but then one day I decided to see how easy it is to get the barrel out for replacement, and ever since I seem to have less power and more jamming. Usually get a jam at the end of a clip. When I get the BB out of the barrel it's easy to see a dent from the follower, but it also looks like half of one side of the bb has been crushed flat. Having one or two jams per clip sure reduces the fun! Is it possible that I've got the barrel misaligned somehow? Any other ideas? Thanks all, JustJim | ||||
