Erster Schuss fällt ab...

[Banzai]

So ich habe mich nun eingeschossen mit meine Impe und bin mehr als zufrieden. Ist so Geil .... :hammer: :hammer:

EIn Problem habe ich aber. Wenn ich eine weile nicht geschossen habe, macht es beim ersten Schuss nur pffft und die Kugel fällt nach 5m auf den Boden. Die nächsten Schüsse gehen dan wieder normal. Kennt Ihr das ? Was kann ich tun ?

ALLES KLAR ICH HABS GEFUNDEN :

Just wanted to give some input to the low first shot problem that a load of members seem to suffer from. After having no evidence of the problem on any one of my team guns for the last few months, this weekend we had 4 out of the 6 guns used in training develope the problem. Now I know there are a million different cures that fly around this forum, including cleaning lube off the back of the hammer, use a 009 o-ring on the ram, etc, etc. Now I build and maintain all the Banzais team guns (as player on Banzais and worker at Planet Eclipse, it makes sense!!!!!) and I obviously know the history of every single gun on the team. So during training I did a couple of experiments to isolate the problem down to one specific area or component. I felt it had to be one specific problem for all the guns to develop identical symptoms, simultaniously. The final test that gave me the conclusive evidence of the culprit (sounds like a who-dunit!!) was this:-
Chrono the gun with several shots, and note the highest and lowest shots. Now let the gun sit. Let it sit for the period of time that you know usually causes a low first shot. For some that may be a minute, for others it may be 5. Now you can switch the gun on and off if you want, but it is better to leave it gassed, obvioulsy. Now, after that period, push on the back of the bolt, or the bolt pin, just far enough that it breaks any contact with the ram and bolt in the rear position, and then let it spring back into the rear, cocked, position. You don't want to push it all the way forward, or you will push a ball into the barrel, and another will fall in behind it when you let it go. Not Good! What you are doing here is breaking the "stiction" of the bolt, hammer, and ram system, and "simulated" a fired shot in those components. If you now fire the gun, straight after pushing the bolt, you will find one of two things. Either the next shot will be at full velocity, or not. If not, it will be lower than the lowest shot in the string before you let the gun sit. If you find that that shot was full velocity, it means you have a sticky bolt, hammer or ram. Clean them all and re-lube, and I always prefere Airlube to Dow33, but that's just me (less sticky).

However, if that shot is still low, like every one of my team guns was, then it is stickyness in the solenoid that is causing the low shot. After further testing it was definately the solenoid that was causing the first shot low problem in every gun we tried. I took out the solenoid, cleaned the spool of ALL grease, cleaned the pilot ports in the middle section of the solenoid with strands of wire and wiped clean the plunger and spring. I then LIGHTLY greased the spool with Dow33 and re-assembled the solenoid and gun. After doing this to every gun, the problem was completely irradicated. We left all the guns for up to an hour and saw not even 5 foot drop in velocity for the first shot. For your interest we have a complete mix of stainless, delrin, titanium and aluminium hammers, bolts and shafts, and a mixture of LPR set-up guns and regular run Impulses. The problem and the cure was universal. No set-up seemed any more susceptable than any other.

So, I hope you all understand what I am saying.

Many thanks
