A5BLASTER Wrote:Think it's 1/8 of inch from bottom of bore line to top of bayonet surface. What I have found is you want your muzzle or muzzle device to stop just short of the long flat area of the bayonet.
i did notice the v3 has a rail mount, i could work with that. but at 399 i would question if i should just get a labradar for 559 or not

They are both what I would consider to be top line for the typical to above average shooter (what's top for serious competitors, I wouldn't know).
That being said, each one has it advantages and disadvantages.
I've been with the mgspd for several years and don't have any need to look elsewhere, I upgraded to the v3 about a year ago.
I use it for all of my load development work.
You can take any straight aluminum cleaning rod piece or a 1/4" dowel and lay it from muzzle end back into the barrel for several inches, and judge straightness and nearness of the blade to your bullet path.
The other thing I do is to periodically sight from bolt end down the tube to verify I see 0 of the blade...
For a nominal 0.7/0.75 inch diameter muzzle end the distance is fine.
Tapered barrels like bolt/ sporters tend to have some alignment issues but you can fix that with a small pad of duck tape, adjust to taste.
Also you can adjust the sensitivity of the blade if the distance seems a bit far.
Using the aluminum rod piece or dowel is the best way IMO to verify distance and alignment.

The V3 is more versatile than the Sporter. Like A5 said I intend to upgrade to the V3 as the Sporter doesn't take the adapters.

mdram Wrote:i did notice the v3 has a rail mount, i could work with that. but at 399 i would question if i should just get a labradar for 559 or notFor me, money wasnt an object. I dont see the V3 or the labradar being all that expensive. I went with the V3 because it suits me better. Once I get the load that shoots best for me. I load up several hundred. Then I chronograph five,and get an average.That number and my Ballistic app is enough to get me on paper at 600yrds.
But some guys like to chronograph every shot.I wouldnt want to shoot out to 600 yards with the V3 attached to my muzzle.And thats where the labradar excels.I used to think that the V3 was much better.But now that my shooting buddy got a labradar,I can see why people like it so much. It would be ideal if you knew people that owned one of each. So you can see the pros and cons of owning each them.They both have their pros and cons.
My choice will always be the V3. Because its compact and I can set it up just as quickly as I can pack it up(2min).But they are really two different camps. So you have to ask yourself,do I want to chronograph every shot? If you do ,get the labradar.

mdram Wrote:question about the magneto speed.
how much barrel is needed to attach it?
i have an 18" hand guard with a 20" barrel
by the tme threads are on i figre only 1-1.5" of actual barrel is available
Why not just attach it to the hand guard. I have the v3 and it's pretty versatile. Plenty of spacers for adjustment. I've attached mine to the barrel on my 20" Grendel and to the handguard on my 12.5" pistol.

First of all, I have no experience with a Magneto Speed. From what I have read it sounds like an excellent chronograph, but I shoot rifles and pistols. Might be a little hard to mount on a 1911 :-). There have been many stories regarding barrel mounting affecting group size and POI change, and just as many saying that it has no effect. I find it hard to believe that hanging anything on a barrel has no effect, just look at the conversations about brakes of different types. I just don't know for sure one way or another
The Labradar has a few issues of it's own, one of which is the more complex operation, and another is the lousy sighting system.
The settings and operation you just have to learn, it's not that hard. Sighting can be somewhat critical, the better you have it sighted the better it tracks. I set mine up with an inexpensive reflex red dot sight, made life much simpler for me and easy to tell at a glance if the unit has been shifted for whatever reason. Beats hell out of that stupid little V notch, but additional expense.
I like being able to shoot for group and sight setting and being able to chronograph at the same time and also use it for handguns, without lighting conditions affecting readings, as with optical types, and no way it can have any effect on groups. The more velocities you can record, the better data base you have for prediction. So it was Labradar for me.
My retirement income level means that I had to wait longer and squeeze things a little to get one, not sorry,

Mine works great. IAM assuming your talking about the sporter model. The only drawback is that the 9 volt battery compartment is not secured very well, but an easy fix.

speed measurement=LABRadar, anything else is waste of $$

I added a https://www.wiserprecision.com/products/chrono-mount to my sporter chrono because of having muzzle brakes on rifles with a 16 barrel with a 15 handguard and a 18 barrel with a 15 handguard. Still have less than a V3 model or a Labradar

I grabbed one of these as well. Fantastic and well worth the price.

Old Bob Wrote:The range for the R & P club I belong to is right next to an international airport. There are a couple of large radar stations on the airport. One of them is about a quarter mile from the firing line I would use for load testing. Could these large radars cause interference with labradar chronographs? I've never seen anyone at the range using one.
Interference should be minimal to nil.
Specs in the LabRadar manual list an operating frequency of
24.080 to 24.168 GHz, using 8 MHz steps for Doppler.
L band: 1-2 GHz - ATC centers, long range air traffic radar
S band: 2-4 GHz - TRACON (terminal air traffic control); long range Wx
C band: 4-8 GHz - Satellite transponders; Wx radar
X band: 8-12 GHz - Old missile guidance; marine Wx; ASDE-X aircraft surface movement
Ku band: 12-18 GHz - Police; Hi res mapping
K band: 18-27 GHz - Wx Cloud tops; Police
Ka band: 27-40 GHz - Airport Traffic Surface Surveillance; mapping
LabRadar would fall in the K band. Because it uses Doppler waveforms, it should be very effective at rejecting strong in band but uncorrelated signals. I wouldnt worry about it near an airport terminal radar - apples & oranges.

Thanks Growler. I just might invest in a LabRadar for my load work. Like I said, I've never seen anyone at our range with LabRadar or Magneto Speed either. Everyone I see is still using sky screen chronographs.
As for the K band frequency range, where the rifle range is, I doubt the police would be running speed traps!
