FPS testing

[GaryG]

I got my chronograph  today and had a lot of fun seeing how it works!  I don't know if I am doing it right,
but I did not use the clamping mechanisms provided, I just held each gun so I it shot through the sensors.
All the instruction were in Chinese, can someone translate for me?
I first tested my:

*Benjamin 130 pistol....3 pumps = 203 FPS, 6 pumps = 308 FPS and 10 pumps = 377 FPS.
*Benjamin 310 rifle....3 pumps = 544 FPS, 6 pumps = 685 FPS and 10 pumps = 774 FPS.
*Daisy model #25....1 pump + 305 FPS.
*Benjamin 317.....we will see!

The Benjamin test used Meisterkugeln 7.0 pellets and the Daisy 25 used Daisy BBs.

I think 305 FPS is a bit weak for a resealed 1960's Daisy No. 25.  I did it myself......  Is there any adjustment to increase the FPS on that air rifle?

Did you get the $30 one,  if so that chrono reads in meters per second,
there is a formula that you can use to convert to FPS, I am attempting to find it...............

Here is the formula for converting MPS to FPS = MPS x 3.28084 = FPS

I use a chrony made by Granny Smith Inc.

It work beautifully for my purpose of killing small game effectively.

From 20 yards & 8 pumps it needs to go right through the apple un-hesitantly.

The Daisy Model 25 uses a cocking spring with a striker Pin.....no seals! It's NOT an airgun The plunger pin strikes the BB and If that pin breaks...nothing happens! I found this out when I was 10 years old.
 A more realistic reading would be about 240 fps. for a '60's model.  BTW, the earlier '50 models had a more powerful spring. Just my 2 cents! dave

So it sounds like 305 FPS is acceptable for a 1960's Daisy 25!  It sure seems whimpy
compared to my Benjamin 310 or even my Benjamin 130 pistol.

There are quite a few mps-fps conversion calculators.............

so on and so forth.........

In this thread there is a translation of the chicom manual. You just need to read until you find it.

Your Chrony is reading fps. no need for any metric conversions! BTW,  My first BB gun was a used Model 25 my dad bought from my Uncle in 1959 for $5.00 . Next one was a Benjamin 312 I bought Brand new in 1964 for about $22.00. The two are apples and oranges. Sold the Benjamin to my buddy for $15.00 to buy a Crosman 180. Later I bought another 312 because I missed having one! Well, after over 20+ airguns now, I finally entered the big leagues laying down about $1700.00 for a Benjamin Marauder, 550 cu.in. tank, cases, scope...the works! The difference between the men and boys is the price of their toys  ;)dave

My crony said 92.9 MPS and I converted it to 305 FPS.  I assume that is normal for a 1960's Daisy No.25.

I'm going to stick with the old air guns that's nearly as old as I am!
