LOL!

Hello everyone!

After using my trusty Chrono for 21 years (a Competition Electronics Pact 1 model) I decided to buy a new Pro-Chrono Digital.

At first it was heartwrenching because it was supposed to be sent to me while I was in California, but it never got to the hotel in time, so I instructed the hotel to refuse the shipment and wrote Competition Electronics to send it to a friend in NY. Of course their first reaction was to charge for the double shipment, but when I told them that I had been a loyal customer for 21 years, they dropped the double shipping charge. I have nothing but good words for Crystal Bailey and the crew at Competition Electronics.

The new model does some good maths and also has memory, so it saves a ton of valuable shooting time as it remembers what you would otherwise have had to write down to process. Maybe some day I'll buy the PC interfase, but for now, it will do as it is.

I took the D-54 out to play and took the Chrono along. Even though the rifle is new and it still has to settle down with barely a tin and a half of pellets down the barrel, I had expected somewhat higher MV, but as I took the Chrono readings, I started seeing that the consistency of the rifle is very good.

It also became apparent that shooting at Tuna cans placed at 55-60 meters (60-66 yards) makes for good training and it also establishes good benchmarks for which pellets perform better than others. For this foray I had GAMO Rockets, RWS Super H Points and JSB Jumbos (the normal 16 grains ones).

Super H Points chronoed at 723 fps on the average, Rockets chronoed at 709 fps average and the JSB's chronoed at 700 fps even on average. All strings of 25 shots.

Notwithstanding the relatively similar MV's, JSB's hit about 4" higher than SuperH's and 2" higher than Rockets at the established distance. I have to assume that the BC will have a similar correlation. I could still hit the tuna cans about 90% of the time using "Arkansas elevation" and "Kentucky windage" with the Mil-dots in my Leapers.

But Chrono figures and tuna cans can only entertain you so far, right?

So I put 15 JSB's into my pocket and went after more interesting targets. ¿Result?

Here it is:



Count 'em! LOL!

Had a wonderful time and now I can put the Chrono back in the box and forget about it till I feel that good ole' "Katharina" has settled in and needs new chronoing. And before I change all the innards!

Anyway, happy camper here on all counts. Now that the weather is improving, get out and play!



Un Abrazo!

Those numbers seem kinda low.

is in or near Mexico City several thousand feet above sea level.


Herb

so, these numbers are at sea level. Quite hot and humid, but at sea level.

First Chrono Screen was 3" in front of muzzle.

The gun is relatively new, only a tin and a half through it. So it is settling-in, still.

Have not done anything to the innards, yet. I already have the spring, the seal and the lubricants ready, when the situation warrants it, I will put the JM parts in.

Probably net, simple message is that 17 ft-lbs is plenty enough to hunt big Keel Tailed Grackles at 70 yards.

HTH

Crows did not think so (LOL) What do think Hector, did you tune it?

are they all from Puerto Vallata, Jalisco? Hector

700 fps with 16 grain pellets are bad for crows' LOL

take care my friend

PS: found out air guns are completely LEGAL and I can take them to Costa Rica


and remember "it's 30% the gun and 70% the shooter"

Yes, they are all local. I needed three more pellets than strictly necessary for pure O-S-O-K's because:

I missed cleanly one shot at about 70 yards. The grackle flew away with less feathers, but flew away in complete health.
I needed to finish off two large grackles where the shots went slightly low and hit under the collarbones. The size of the grackles "lied" to me when estimating the distance with the mil-dots and the hits went slightly low. Live and learn.

Good about Costa Rica! They have some of the best natural places on earth.

Not yet.

Have all components on hand, will tune it when the situation warrants it, either because the original spring breaks, or because the factory guide begins to be too loose. It's a somewhat subjective question of "ear". You need to "hear" what your gun does so that you can decide when is the best time to tune it.

Partly you want to settle the barrel down with the factory spring, and make sure that when the moment comes to tune it, the time you invest in it will be good for a long time.

And yes!, Grackles did not mention anything about low MV's! LOL!





Un Abrazo!
