Ballistic Coefficient Data Eley Contact 22LR

[InTheSticks]

Can't seem to find much on this even on Eley's website, I am trying to load up iStrelok with the data for this bullet - any ideas where any charts are ?

Am just starting off getting to grips with this so that's about where my knowledge and experience sits. thanks

I think I measured the BC of some standard 40 grain RN Sub Sonic at .121 @ 3000 ft above sea level on a 70 degree day. Don't bank on that number as my memory is not what it should be. It's probably close though.  How far are you planning on shooting?~Andrew

There's a whole list of .22lr BC's here - not sure how accurate they are. I've found that to get accurate results with Strelok and .22lr ammunition you really need to run a few of the same batch through the chrony, the results often don't relate to published velocity and there is often quite a wide ES. Ok up to about 70 yards then the guesswork creeps in.
