22 Wolf Match Target          966 fps, SD=10.1 fps
22 SK Pistol Match Special   969 fps, SD=14.5 fps
22 Eley Target                    987 fps, SD=5.3   fps
22 CCI SV                          968 fps, SD=14.3 fps
22 Fed Gold Medal 900B      992 fps, SD=18.1 fps
22 Blazer                          1135 fps, SD=23.6 fps

What is considered the standard distance for chronograph use for pistols?

6 ft?
10 Ft?

It is only a number....as long as you always use the same number it does not matter.

Dr Don's rimfire numbers reflect the testing I did a couple years back, with the exception of the Eley Sport which I didn't have.  Ten round groups were fired at 25 yards with an M41 and the chrono set at 10 ft.  I found the best ten round group was with Eley Target, X-ring size.  The largest grouping was with CCI std vel which grouped one inch. The Blazer grouped about the same as CCI std vel, much to my surprise.

If it is of interest, I have a file of some chronographing I did many years ago:

Excel Version of .22 and .45 Ammo Testing

Note: There is some link that may try to update from a different file - tell it No - I've never been able to remove the link request.
