AA s410 Chrono test results

[markha 99]

Today saw the arrival in the post of a combro cb625 Mk4 chrono.

This thing is fantastic, so simple to set up and use.

 

I have probably put around 200 slugs through my new AA S410, so its not run in yet. I did ring AA yesterday to ask them what the factory test was, he said it came out between 550-560 ftlbs edit:hahahaha FPS, Well spotted Phantom I took his word

 

AA Diablo Field 5.52 16.4gr

av 550fps

av 11.1 ftlbs

 

H&N FTT 5.53 15.1gr

av 561fps

av 11.6 ftlbs

 

Premier Ultra Magnum 14.3gr

av 548fps

av 10.3 ftlbs

 

So Im very happy that i dont have one of the rogue low power guns.

Cheers

Mark

Well I was a bit quiet work wise today so decided to run a whole heap of shots through the chrono.

 

Started at 190 bar fill and finished at 100 bar.

 

starting ftlbs was 10.92

finishing at 10.68

 

Lowest was 10.52 and highest was 11.47

 

All with AA diablo fields 16.4gr

 

The sweet spot was definately from around 25 shots in from a 190 bar fill right through to the 65th shot at around 130 bar, Or a starting fill of around 175 bar to be on the sweet spot. So a possible 40 consistent shots.

 

Boring but true and I only had to do it once, now what else can the devil do for idle hands

How did you reach that pellet weight mate?

AA fields are listed in chairgun at 15.9 grains... I have weighed thousands of them and usually varies betweem 15.8 and 16.2 so I use 16grain as a good average.

If they are really 16grain then your readings are really around max 11.2 min 10.2

Thats interesting Stevieskin as Air Arms factory quoted the 5.52 diablo field ,over the phone , as being 16.4gr so thats what I based the chrono on, i havent weighed them myself as I dont have scales, and bow to your weighing of a lot of them and will call them 16gr as an average.

 

Cheers for that info.

here you go mate, on the lid of AA field 5.52 it says weight is 1.037 grams

If you use this converter it comes out at 16.0033grains.

40 consistant shots sounds about right

 

Fill to 180 then let a few go at the paper before you begin your hunt once you've put 3 to 5 in the bull, your in and ready

I always used 15.9 grains as the weight of the AAF pellets (thats what it says on the tin)

 

Glad to have been a help, now I certainly can think of a million things to do for idle hands goes like this:

 

1. Refil Gun

2. Pellets in pocket or pouch

3. A few at paper

4. Mooch until target spotted,

5. Load and make ready.

6. Aim

7. Fire,

8......... you get the picture lol

Thats good results then! My 2007 model s410 carbine pushes out a healthy 11.4, but my mates anti tamper one only pushes out 9.something.
