Labradar velocity??

[JPeelen]

Brian,
I looks like you are in the happy situation of only shooting outdoors.
On the concrete floor of a covered range, you will find a lot of unburned kernels in front of the shooter positions. Its enough to require sweeping up after each day of shooting to avoid fire hazard.

All the powder has burned in the first foot or so of barrel.

If that was true, then there would never be ANY muzzle flash.

Regardless of the cause of your problem I would call them over there. They’re great with customer service. I was having a problem and they actually told me to call them next time I was on the range and they would work with me in real time to resolve the issue. All is good with mine now. Turns out it was a positioning issue and they just help me tweak it.

Muzzle flash (in rifles, anyway) is generally caused not by unburned powder, but by the reignition of the powder gases when they suddenly encounter extra oxygen upon exiting the muzzle. The powder gases themselves are combustible and the additional oxygen allows them to flashover. This is also why most flash suppressors are designed to break up the large cloud of these gasses as they exit the muzzle. Spreading the cloud can often prevent it from reigniting in one large mass, thereby preventing the very visible flash from occurring.

After setting up again I have not had a repeat of the high Velocity #s for my larger bores.
Now I cant get it to track my 204R shots!
Are they too small to detect?

Could be either too small or too fast I.E. 3,900+ Also small boattail could be hard to detect.

I have never had this issue but a guy at our range has had a similar issue. He ended up bumping his reading range out to start at 20 yds and that seemed to fix his issue. I have mine starting at 10 yds. with no problems.

I've been able to reliably track Sierra 39gr bullets fired from a 20p. Velocity is under the ~3900 fps ceiling for the LBR.

 

[Lefty Trigger]

Mine is getting my 22-250 50gr, 55gr, 60gr bullets at around 3500-3700 without issue

The Labradar will not measure past like 3900fps. The folks at Labradar told me this was a mechanical limitation that they could not extend. (They May have said 4000fps. Been a while and I don’t remember which).
