It would be very interesting to strap a Magnetospeed on the next time you run the radar.

They said that the remote triggers can have an impact based on where they are positioned. According to them, the best resultswhen using a remote trigger occur when the trigger is positioned on the barrel near the end of the muzzle. I didn't want anything on my barrel affecting accuracy so I was mounted on the stock hear the action.
When I go back, I'm going to shoot without the trigger and with the trigger mounted at the end of the barrel to compare data.
agreed. Unfortunately, I don't have one.
I have used my Labradar in an indoor lane with the JKL trigger. I've read that you need to set it at a lower power which was fine for a 458 Lott but would not clock a 300 Weatherby. In my indoor range (50m btw) I found it was the side baffles between benches that was the issue. I placed my Labradar more to the centre of the lane and got readings each time.
Also in terms of mounting I velcro my JKL trigger to a sling swivel and just attach that when I shoot. Never fails to trigger.
My readings have not varied between indoor and outdoor.
Without the JKL it was a bit hit or miss to get reading with muzzle brakes guns although I think it's the way the range is set up that creates the problems.
Hope this helps.

I'm getting readings, they're just slow. One gun/load I wouldn't be focused on the radar. 3 guns w 5 loads and all 50-75 FPS slower than expected….kinda hard to not think something is going on.

I don't buy that it's the fault of the trigger. Mechanically, either the trigger will "trigger" or it won't. I don't see how it could "sort of" trigger in a way that would affect the velocity reading. Maybe I'm wrong; following to see what you learn.

I routinely check my LabRadar against my Magnetospeed. I do this when shooting foulers, then remove the Magnetospeed and shoot the loads I am testing using just the LabRadar. The co-measurements usually agree to within the stated accuracy of the units, which is about 0.1% under good conditions, e.g. 3 fps for a 3000 fps load.

I mounted mine on the barrel about half way. If that affects accuracy then I'd would seriously consider getting a new barrel
I was wondering about any problems with indoor ranges a few days ago. Following
