    Shooting chronograph-chrony

    I searched for active threads on chonographs, but didnt find so i opened a new one. I need your honest feed backs, personal experiances, price and availbility, which one is over rated which one is under rated which to buy which one not to buy and most importantly from where to buy ?
    I just need an idea about there usage and market, I am not buying one for time being but will definatly buy one in near future.
    Regards.........

    Go with an Ehler 35 P. It is expansive but if you use one regularly this will save you money. All the friends I know have shot their Chronies 2 or 3 times and then bought the expansive one making it more expansive.

    Salam,
    Very true Skeeter60, sir... but the main thing is price, the oehler 35p costs around $600 in the USA, while the shooting chrony can be had at around $120. But care needs to be taken not to shoot it

    I received my chrony day before yesterday. Its the Alpha Master version. Also tested my airguns. Will post the results in a while.

    Regards.

    Hi

    Magnetospeed (I use one of these in load development)and Steinertsensingsystems do chronographs that cannot get shot or damaged - certainly more expensive to start with but more versatile with minimal risk of damage..........would be worth considering in my opinion and experience.

    Salam,
    Have been playing around with the chrony with some very astonishing results.

    The 34 averaged 691 with Gamo match. ES of 18

    But...... the most mind boggling of all:

    It averaged 670 with H&N FTT with an ES of 32.

    Honestly, I was shocked. I then thought maybe it was because of the 5.53 head size, and a pretty tight fit in the barrel. I then tried some Crosman Ultra Mags(since they are tightest fit in the barrel), but got the following results.

    Averaged 712fps with the Crosman Ultra magnums. Extreme spread of 12, so pretty tight.

    So, I did some research. I found out the following

    1. The advertised weight of the FTT is not correct. Reported weights vary from 14.80 grains to 15.60 grains.
    2. Earlier FTT tins were usually over 15.5 grains

    Ok, so maybe I got an old tin. But I am now searching for a digital scale before I open a couple of new tins that I just recently got. Hopefully, will get some meaningful results.

    Last, but not least, I now have new respect for the term "Ignorance is Bliss"

    Salam All,
    A quick update.

    1st about the FTT's...well the tin that I had, whose results are given in the previous post, was marked 25 joules. That was probably a bad batch or something, but the newer tins that are marked 16 joules are more consistent, and the unexpected flyers are gone.

    Its been a few days that I have been thinking of detuning the D34 to a lower power level to reduce its hold sensitivity, since I also own a D52 if I need extra power. I thought that since I have a brand new spare spring, why not experiment with the current spring, maybe cut a few coils off, to bring the power down. So I got my log book out, added the pellets shot after I installed the new spring and lube tuned the gun. It added to a total of 2443 pellets. I then proceeded to chrono the gun so that I have starting data before any mods. The test was done with pellets straight out of a brand new box. The results are unbelievable. I was first shocked and then extremely happy.

    Pellets : H&N FTT 14.66

    1.680.9
    2.682.4
    3.683.7
    4.682.6
    5.681
    6.682.5
    7.683.4
    8.681.3
    9.683.3
    10.682.6

    Low 680.9
    High 683.7
    Ave 682.4
    Extreme Spread 2.77
    Standard Deviation 1

    In all honesty, even regulated pcps dont have a shot string that's so tight.
    Now, I'm having second thoughts about messing with it at all. Lets see.

    Regards.

    Can you send a link sir, we have to borrow cronies from people when we field test local ammo. It would be great to get hold of a something on our own

    Just saw this post, I have a Diana mod34 too. After basic lube tuning the weapon, I also checked the velocities on chrony.... After about 1500 shots or so it was shooting at around 720 fps and the spread was pretty much the same as what you have mentioned... I too am facing similar kind of observations as mentioned by you. The rifle is capable of great accuracy, just extremely hold sensitive... I have shot excellent and evenly pathetic shots on the same day using the same pellets. I have been experimenting with the FTTs and Crossman

    Can you email me your contact details at deathrow.pg@gmail.com, Perhaps we can share some valuable information with each other to get the best out of this airgun.

    Salam ED Bro,
    Hope you're well. Here's the link, but i dont know whether they'll ship to Pakistan, and what the custom charges will be...since a friend of mine got it for me when he was visiting Pakistan.
