Anyone heard of Magnetospeed LLC chronographs?

Pretty cool looking concept. Uses magnets just under the barrel to clock speed. They are a local to me company and seem resonably priced if they work as advertised. Link and picture from their site below. No affiliation, just curious.

[Bear24]

Yes! I have had mine for a few months now and it is really awesome! Very easy to use and no worries about going down range to set it up or worry about lighting conditions.

 

[shoot4fun]

Go for it!
Great product.

 

[Joey Dean]

Great piece of kit. I have the V2.

 

[HobbyShooter]

Would having it on the end of your barrel like that affect barrel harmonics? Does it seem to affect accuracy?

 

[bodywerks]

Not sure about harmonics, as is not much weight. It doesn't seem to affect accuracy for me, but three is a rather predictable poi shift. Some have speculated that it has to with high pressure gases from the muzzle reflecting off the magneto speed and bouncing back up against the bullet as it leaves. I tend to agree, because the impact is always high and right with it attached.

same results for me as well, in my 308 the 155's are shifted about 2 MOA high and the 178's are about 1.5 MOA high

The magneto speed V2 has been my best purchase so far. It's great to not have to worry about weather when going out to chrono loads.

 

[damoncali]

Do a search - there are a few threads floating around that get into various sources of POI shift that are theoretically possible. I'm looking into one now, and was concerned about adding weight to the end of the barrel, but after some thought, I doubt it matters that much (this is pure speculation) because the strap that holds the dohicky on the end of hte barrel is very soft relative to, say, a threaded joint. That could in theory alleviate the impact of the weight.

From all of the threads across the net I've read, there seems to be no consensus as to a reliable POI shift. Some report one, some don't. Sounds like you need to verify things without the chronograph on to be sure.

I have one and love it!!!! However, I don't know why people worry so much about accuracy when doing work with a chrono. You really need to just worry about getting your numbers and then use them to get your accuracy.

 

[TAF070]

I can 2nd Dutch405 I have used his several times at the range and have never missed a reading these are 100% reliable regardless of the weather! Great chrono!!

 

[smschulz]

Love mine, easy to use, easy setup and appears to be accurate.

+10 to Jim on that one. Need numbers on yer load before trying to shoot for accuracy. Could save alot of time at the range and wasted dollars.

 

[Paulyr450]

I got my magnetospeed about 3 weeks ago and it works great. The best thing is the setup and the fact there is no more light problems.

Awesome product. I have one with a V1 bayo and a V2 bayo.

Accurate

Easy

And like bodywerks said, predictable POI shift. For me same as bodywerks, up and slightly right.

 

[BC 6.8]

I have one and really like it. It never misses a measurement regardless of weather, and I don't have to go down range to set it up. The POI shift is predictable as said above.

 

[Bluesop7]

Has anyone done an identical OCW with and without the magntospeed to see if the results are affected by the bayo being attached? Obviously you will have a POI shift with it attached but I dont necessarily think that would skew an OCW. I sure would be nice to do an OWC with it attached.

Did you see the thread here
http://www.snipershide.com/shooting...t/118495-magnetospeed-chronograph-review.html

I like mine

 

[TXLEO]

I did not. Good thorough review!

 

[Sniper Uncle]

I used on from a friend of mine. I can't say I really saw a POI shift at 100 yards on my 30.06. I also wonder if the POI shift is as pronounced with a good muzzle brake on that diverts the blast sideways and up??? I was chrono-ing with my chrony and his magneto, and they were close in measurement. I liked it very well, and would like to buy one, but have other priorities first. Maybe someday I can afford one....

 

[fx77]

Have owned every (that's right every one ) chrono on the market...
Love the Magneto Speed..so easy to setup and to use.

 

[Bear24]

I am fairly new to the precision rifle reloading and I bought mine after i was gettin frustrated with load workup. Things made much more sense after I started using it and I get the same groups with or without the bayo just a slight POI shift.

All you have to do is work up the load and test it with the bayo on, once you are good to go, pull it off and zero... DONE

 

[Bluesop7]

I finally ordered one after months of deliberation. This will be my first chrono, so I'm pretty excited. I will definitely be trying with and without the bayo attached for OCW load development.

 

[Squid284]

Wish I would have bought one before the other two I've purchased... but it didn't exist back then. You won't regret it. It had a little bit of trouble picking up my AR rounds but I just had to tweak the settings a little. My 7mag shoots about 1 MOA higher with it on.

 

[bolt56]

Has anyone compared it to other chronos?

 

[Sniper Uncle]

Has anyone compared it to other chronos?

Yes. My friend Kevin has one, and we put it on the barrel of my 30.06, and ran in in conjunction with my pro-chrono. The numbers were at slight variance, but consistent with one another. I liked it, and would buy one when I can afford to.

^^^^ THIS

I have the V1 and am very happy with it. Very accurate and spot on numbers.

My range time is at more at a premium than even my ammo is. That is why I would want to get accuracy while chrono-ing, because then I can develop an accurate load and know what speed it is at the same time. If the magneto chrono affects point of impact, but is very consistent in that affect, then the group would remain the same size, and POI can be adjusted later.

 

[Sendero_Man]

Here is what 2 rifles did with the Magneto Speed on them...

And the other....

I briefly compared it to my shooting chrony, in short easier setup and use and much more consistent with one range session to the next with no concern for light levels.

Now, where it counts is at the range… accurately tracking with observed drops. I have done this multiple times at my 1000 yard range where I factor in real time velocity data with current environmental data and a known BC. The data I get matches up not only in the average drop required but in back tracking slower and/or faster velocities within that group, it matches the point of impact of those that went high and/or low.

That tells me the magnetospeed is very accurate.

This has also helped me find true bc’s for bullets not yet cataloged by Bryan Litz or measured by manufactures in real time rather than the more common computer projections.

For instance, the last bullet I tested was the 105 grain Hornady BTHP which I knew had a lower bc than their A-max just from launching both at the same velocity and observing a lower impact with the bthp at every distance past 600 yards. Hornady lists the A-max at .5 g1 and the BTHP at .53 g1… Litz reports the A-max at .492g1 and .252 g7… the bc I have found for my velocity on the bthp (2890-2970 at the muzzle) yields a .475 g1 or .240 g7 at my 1000 yard line.

Now I am going to do it again but with the bthp’s pointed on my pointing die to see how that changes things.

Has anyone compared it to other chronos?

I and some other guys on longrangehunting.com have compared it to an oehler 35, and an acoustic chrono. The magneto read about 5-10 fps faster than the Oehler that was set 15 feet from the muzzle. The acoustic was right in front of the Oehler, and read 20-40 fps faster. We tested them using a 223 rem, 6mmbr, 6.5 SS (similar to the 6.5 saum), 6.5 sherman (similar to the 6.5-06 AI), my 284 win, and a 338 rum.
