EDgun Matador is the #1 PCP in the world...

Postby mamcrackin » Sun Jul 11, 2010 8:48 am

EDIT: This was not a gun problem after all... It was a problem with my adjustable magnification scopes... All 3 scope (Leapers 8-32X56, Nikko Stirling Diamond 10-50X60, and Leapers 4-12X40) were losing their zero and shifting the Point Of Impact every time I moved the magnification adjustment wheel from the lowest setting to the highest setting and back again to the lowest setting...


Eduard, here are some 65yd groups I shot this morning.... It seems that
sometimes it is a laser shooting 3-5 shots on top of each other and then shots
start to fly everywhere... I cleaned the barrel very carefully and shot some 100
shots before shooting these groups... The wind was absolutely zero... My
Combro is on the blink so I could not get any FPS information.... This gun has
well over 10,000 rounds through it. It does not make a difference what
the psi is in the gun and I removed the shroud/mod to make sure it was not
causing any problems. (See group on bottom left that says "No mod")
I also pulled out my Rapid to make sure that it was not the conditions.. The
Rapid shot a 10 shot sub 1" group at 80yds. The EDgun shot 2 sub 3"
groups so I know it was not the wind nor the shooter causing the wild
flyers.... I ordered a new Chrony this morning so I should have FPS info
next week....

Try to chrony to find out the pellet speed.

did you perhaps switch pellets or get a new batch?

I have always used JSB 18.1gr... I shot the rest of one tin yesterday under
windy conditions with the same results... That is why I decided to do some
testing this morning when the conditions were perfect. These groups are from
a new tin. The Rapid had no problem with them so the pellets are good.

beware of different batches of the same type of pellet...

anyway until you can verify velocities over a chrony there is no point in speculating further.

Well, just to get another reference, I just shot 1 X 10 shot group and 1 X
5 shot group with JSB 15.9gr. The first was about 1.3" @ 65 and the
second was about .97" with 3 shots touching and 2 fliers. Seemed to be
working fairly well so I increase the hammer spring to get the 18.1gr
shooting faster. I then switched back to 18.1gr and shot 2 fliers and then
a .5" group. After that the groups would open back up then get tight
again.... Something is not consistent... I also replaced the probe orings
to make sure it was not loosing any power....I will have to wait for the
chrony to see if my FPS is erratic...

All shots not designated are JSB 18.1gr

Shoot it over a chronograph to see what the fps is :P

Mam, I'm te thinking you might want a chrony. Just to find out what the fps is. I'm just guessing here.

I think a chrony would help in this situation as well.

Lol, it just hit me. A chrony mam' !! Its as simple as that. You find out the speed, then that will probably be a good place to start. Try the Combro. I know I've never mentioned it before, but its pretty good. It tells you how fast a pellet is going. Like a chrony F1 or something. That also tells you how fast a pellet is going.
In actual fact, I reckon you could do with one of those. It will tell you how fast the pellet is going, that would be a pretty could place to start.

Most people won't tell you this, but what you really need to do is shoot it over a chronograph to find the speed it is shooting at. People will probably tell you otherwise, but it will help to find the speed and you will also be able to check for consistency between shots.

They really help. You should look into getting one.

Suggestion...

Postby Hoot » Sun Jul 11, 2010 3:14 pm

Has anyone mentioned tightening all the nuts?

With 10,000 shots, vibration can make make things loose.

If that doesn't work, try tightening your nuts just before you pull the trigger. It may not be the rifle at all.

Look carefully at the end of the barrel, looks like you could damage the place where pellets going out the barrel. It should be sharp. Use magnification glass to see if there is not any damages on the edge of the barrel.

Quit the coffee years ago... Gave me stomach cramps. :oops:

I shoot the EDgun a lot... Might have been a few weeks since the last
session... Yep, tried changing the speed but could not tell what I was
doing because I did not have a CHRONY.:shock:

If I only had a chrony, I wouldn't be so moany.
I could shoot all day as the people say, and never be called a phoney.
Thanks Lama.. You're the man....
