Tuning FX Chrony - best / most reliable / accurate "spot" for it?

[jdanvers]

Curious -- at around the 2:10 mark in here - Gert states that he gets the best results out of his at 4-5 inches in front of the barrel. I'll assume he's shooting an inch or so above it - he doesn't state that. I've got one but honestly . . . I like my older competition electronics one better - with the light kit - it's extremely reliable and rarely ever misses any shots. My FX portable on on the other hand - it's kind of jekyll and hyde'ish - and it can sometimes drive me up the wall.

Just curious.

I built a stand for my chrony, yes I has issues getting good repeat accuracy. I used a four ft long board, mounted overhead lights that are in a consistant position above the sky screens. I also built a stationary platform above forvthe barrel to rest on, this way the barrel is always the same height over the chrony as well as same distance back from the sky screens. The whole unit is portable, mabey a little awkward but easily moved to wherever as long as I have a 110 outlet for the lights. This way I always have a reliable reading with no regard to lighting or distance from or how high over the skyscreens. A pellet trap is attached to the back to collect all the lead. Been getting accurite readings for more than 25 years with this setup.

I hang it from below the barrel butted up against the bottle and its flawless. Works out to 4 inches back or so if I had to guess.

What Glem said. I hang mine from the suppressor via rubber bands about two inches back from the end. Works consistently on every weapon I have put it on including pistols.

The best part about hanging it is you can point it anywhere and it'll read! And yeah Charlie mine works well with pistols like that too

Thanks guys. After a re-read of my original post and a re-visit to that video -- looks like I misunderstood - I'm guessing Gert is doing pretty much the same thing as you guys - 4-5" BEHIND the tip of the barrel. NOT in front of it as I had initially interpreted. In the video he indicates with his hand pulling the chrony BACK which jives with what you guys indicate. I'll have to spend some time playing with it.

Gert spends hours behind his rifles testing airgun ammo. He would most definitely have found the perfect placement for the chrony.

 

[Glem.Chally]

Yeah no big secret, its contoured to fit against the barrel and was advertised as such.

As others have said - I mount it to the barrel (no shooting for accuracy when chrono mounted) about 3-4" back from the muzzle. It misses maybe one in every 50 shots this way.
