whats the lowest deviation on your springer

[wastrel]

OH, OH, THAT WAS MY 100TH POST, do I get a-
never mind.

can I just say, if you lot don`t mind, that
I have NFI what you lot are on about
suppose I should use the embarrassed icon now, but I won`t, out of stubborness, so there!

They are discussing the speed of a pellet in fps (feet per second) and how it can vary (deviate) from shot to shot on a particular gun. It is desirable for this variation in speed to be as low as possible for consistancy.
So with Tim's figures:-
775,775.776.778,773,778,778,778,778,775,775,775,775,778,778,779.774,775,775,775
The slowest speed is 773 feet per second and the fastest is 779fps, a difference of 6fps and halve this for the deviation figure +/- 3fps.
So if you take the mean speed, this is the half way point between the highest and lowest speeds, you will get 776fps with a deviation of +/- 3fps over a twenty shot string.

Here you go Eddie, this was a shot string from my Prosport while I was experimenting with a TbT guide and tophat last year sometime. The pellets were AA Fields in 4.52.

very good, do you always use the fps and not the fpe read outs for divination results , as i have all ways used the fpe as mine,

Always used FPS figures, not sure why really. probably because it's round figures and no faffing about with decimal points.
