    Was kind of surprised to only see an 88fps increase going from M855 to M855A1. I thought it was hotter than that?

    That said, haven't they lowered them from the original M855A1 loading?

    My 2¢, having read the directions: It's totally counter-intuitive for anybody who's ever seen/used a regular chrono. Putting the muzzle right next to it just seems wrong, but I guess that's the trick...

    I've had a LabRadar for about a year now, and I love it. I use it for my firearms and for archery. I just have to remember change what triggers it when I switch between the two.

    I bought mine shortly after they first came out. Making sure the settings are correct is imperative. I also always use the remote microphone & it works flawlessly that way. For a power supply, I use a solar rechargeable battery pack that’s Velcro’d on top.
    The only problems I ever have are related to the Bluetooth communication disconnecting from the phone app. I’ve found it’s not worth the hassle so I just track the data on the SD card & not mess with the phone app.

    That Lab seems like the dog to buy. I like it.

    Thread jack.... But, does the length of suppressor impact the variation in velocity?

    It can. Here's an example of how a suppressor can increase muzzle velocity as the result of a barrel not being long enough to facilitate the complete burning of the powder.

    Fast forward to 11 minutes.

    Played with it some more yesterday. Cronoed a bunch of a buddy’s handloads, but thought y’all might have more interest in factory fodder from here on, unless I decide to build up a really nice load.

    62*F, Same 16” BRT Optimum Light 1/8 barrel, now with 5.5k rounds on it, same M4SDk, adding a Sig MCX Virtus 11.5”

    *Fed XM193

    Not much more than the 11.5”. I noticed that the lighter we’ve loaded our handloads, the less difference in barrels. When we approach max, the delta grows. Dunno yet if that is a universal rule.

    16” +can
    Av 2929

    Sd 73.9
    Only added 33fps, but doubled Sd.

    Good Grief. Not to sound snooty, but those spreads and SDs are huge.
