Average vilocity of Diana 52 .22cal

[Maarodigro]

Hi every one ، i have Diana 52 Springer .22 airgun

I need to know the average vilocity speed of this gun for strelok pro.

I know the max velocity of this gun is 850 FPS,

But i want to know average velocity of 10 shots,

If any body knows

827fps average with 14.3 CP's out of the one I had, which, from what I have seen over the years is about the averaged expected. Some a little more, and some a little less. It is hard to push them past the 850fps with a 14.3 pellet range. Max velocity with non-lead pellets that are lighter are way higher than 850fps.

I get 826fps average with the JSB 14.35 with my 52 that has not been shot in over a year. My 54 shoots them slightly slower.

Dear jasmlowe,

You can measure your twist rate by:

1) put a tight fitting patch on a cleaning rod.

2) insert the rod into the barrel. 

3) make a circle around it with a sharpie where it goes into the barrel

4) make an index mark on the circle that lines up with something on the rifle.

5) push the rod into the barrel until you get one full rotation, note the direction of rotation.

6) mark a circle on the rod where it meets the barrel.

7) remove the rod and measure between the circles, one turn.

Now you know direction of rotation and distance per turn. (Someone correct me if I am wrong) Clockwise from the breech towards the muzzle is right hand twist.

I thought it was 1/16 twist but that could be just a number swirling around in my head. Sorry.

Sir jasmlowe,

Thanks for your help
