52nd ISSF World Championship in Changwon

Interesting, full of colours and content opening ceremony. The firework lasted 19 minutes and was very beautiful. To say the truth - I have never seen such long firework. Amazing.

I find the organisation very good. Amazing volunteers' courage. Very helpful and nice people.

You can find some photos in this album. I hope it will be updated daily till the 8th of September.

What we see on the bottom of the grip? Blinking blue led. I suppose it is adapted Walther SSP electronic module. What else...

Revolver Taurus 76 (.32 S&W Long)

Finally got it. From the third attempt.
The first one – my bid lost online auction in October. The second one – potential seller didn’t answered. The last and final successful attempt – bought on the eGun.de.



Since I have never seen Smith & Wesson K32 Masterpiece for sale somewhere near me and Manurhin MR32 is too expensive and also hard to find – tried to find Taurus 76 and now I have it. I am impressed. The quality is better than I expected. Fine surface finish and beautiful bluing.
I hoped that my grip from S&W 14-3 will fit the Taurus’ frame. It fits for 95%. Minor changes are needed to make the grip «interchangeable» but don’t want cut this grip anymore. Taurus will get own grip someday.


I tried to measure the endshake and I got variable results. Endshake varies a little bit for all six chambers and lays between  0,05 and 0,08mm.




Today was the first test shooting. The trigger «as is» (2 or 2,5kg pull force in single action). The original grip. Shooting with one hand at 25m of course. Used very very old reloaded ammo (treasures from late 80s or early 90s?). Bullets are completely oxidized. Brass dark and dry.




Taurus will be my competition revolver for ISSF center fire event (first time with standard factory grip). Shooting revolver makes fun. And no need to used case catcher or pick every case around me after shooting.

ELEY Tenex Air pellets

Update:
ELEY announced new product - Tenex Air.
Also. We tested Eley Tenex Air. Not Eley ventus.


Preamble.
Measurements and tests – is thankless job. Too many factors may vary. I will try to exclude subjective factors and will operate only with observed numbers. At the end of the day shooter will decide what ammo to use.


I was allowed to attend the ammunition test at ELEY shooting range in Birmingham. «The guest» was an air pistol of a good shooter.
ELEY Team tested own new product – Tenex Air pellets – 19 different lots. As some of You know – the ELEY ammunition test consists of two phases. The first phase – 10 shots group test to eliminate obvious «no go» lots. The second phase – several 10-shot series for selected lots (lots passed first phase) to detect constancy pattern and exclude good groups by luck during the first phase. Of course the team also tested currently used ammunition by that pistol shooter (the ammunition is believed to be very good with tight groups). The detailed test took 4 or 5 hours. Vice with clamping tools specially milled for that type of air pistol, chronograph and Meyton equipment to get X,Y coordinates :-)
Compressed air cylinder was refilled every 40-50 shots (pressure range during the tests 190-120 bar). But it doesn't really matter I think... the velocity was constant according to the chronograph (most of the tests approx. +/- 1m/s... and the best observed test approx. +/- 0.5m/s). I have never seen such constancy with my typical pellets for hobby shooters like me. Good selected air pistol or premium ELEY pellet quality? Or both? I don't know.

JSB Match Diabolo. Labeled on the tin as 4.49mm.
Measured with laser (contactless) – 4.5099mm.

RWS R10 Match Premium Line. Labeled on the tin as 4.49mm.
Measured with laser (contactless) – 4.5020mm.

The measurement with the caliper will show 4.49mm I suppose.
To say truth – I forgot to ask ELEY for measurements of Tenex Air (printed results like above). Therefore I don't know if Tenex Air caliber declared as 4.49mm, 4.50mm and 4.51mm are real. The competitor pellet's weight was OK (+/- constant and as declared on the tin). The chemical composition is approx. the same according to the ELEY lab results.

The numbers for that particular pistol/barrel and other conditions on that day (all groups are measured edge to edge / the velocity was approx. the same +/-):
  • 19 Tenex Air lots (4.49, 4.50 and 4.51mm) and two competitors (JSB and R10 both declared as 4.49mm) were tested
  • R10 - best achieved 10 shot group was 8.3mm and the average was 8.7mm (3x10 shots test)
  • JSB - best achieved 10 shot group was 7.0mm and the average was 8.4mm (3x10 shots test)
  • 7 Tenex Air lots passed the first phase (<= 7.4mm - absolutely free selected criterion) and were tested once again in the second phase.
  • In the second phase 6 of 7 lots of Tenex Air outperformed tested competitor's pellets:
    average values were 7.6, 7.3, 7.7, 7.6, 8.9, 7.7 and 7.9mm.
  • The Tenex Air lot with the average 7.3mm also showed best 10 shot group of the day - 6.8mm.
Conclusion:
Typical 10 or 5 shot paper target tests are not sufficient (forget it now). You may think that your gun shoots «hole in hole» but it's not true. Additionally we have to exclude any «good» group by luck. Long tests needed.
ELEY invests much time and efforts in .22lr TENEX tests with customers. The same approach for .177?
Plastic box divided in several sectors is OK. Prevents the pellets from damage if the box is't full anymore (do You remember metal tin with 50 last pellets? Yeah... let's shake it baby :-)).

Other impressions:
I had a short factory tour. ELEY automatically tests .22lr cartridges in so many ways during the production cycle. So much efforts to make Eley shooters happy (especially Tenex shooters from ISSF pool).
