Thread: Chronographs, what's the story

Yesterday I shot some new powder for groups, chrony readings reasonably steady, I mean not to much variation, sorted out a couple of loads that looked interesting and took them back today for a recheck.
Same load , same sort of grouping but readings near 100FPS faster the readings were as reasonably steady as yesterday.

Had the sun shields on both days, sun not out as much yesterday, but still there, but bright today,
then clould cover came over and the speed dropped 50-80-fps for the same grn weight.

Drives me nuts, anybody got a solution.

Validate at distance is the only solution I got, it's a real piss off as it happens to me every time I go out and not willing to spend big bucks on a flash chrony...

Your right, thats the only true way, but it just drives me fuken nuts cause it happens time and time again, you think you have it sorted, then bugger the damn things are supposedly going faster.

Glad I'm not the only one that doubts the chronograph ha ha

Now you know why I got an Oehler

You still need to validate at distances but at least I know the speeds are about right.

Shame about the $$$ not worth it unless you are doing heaps.

These sonic things, anyone have an opinion about them yet?

I only trust it when it's sunny. The numbers from clear, bright sunlight seem to line up at long range.

What brands are you guys using? I use a Competition Electronics one, it seems to be more reliable than my friends shooting chrony (the Canadian made ones). The numbers seem to stack up at distance, and it's never thrown a hissy fit on me.

F1 shooting chrony

Shooting F1

it's been shot, hit with fragments from an exploding suppressor, and still works

it just needs bright light to be accurate

i have got an oelher and a pro chrono which reads to with in 4fps of the oelher so mainly use the prochrono and then verify by shooting

My 338 Lapua blast blew the front off my F1 and rolled it around a tad I managed to fit it back together still working but I use a Magnetospeed now seems simpler but it has affected my grouping and point of impact.

I modified mine with a 480gr round ball at 1200fps. Rolled the bugger in the dirt too... On comparison to all my previous loads, it's still spot on and I still use it.

still works?

Sure does. Amazing as it still reads consistent to my loads.
