Magneto Speed Alternate Mounting Options effectiveness.

[dave300]

So, I have a question that I hope anyone whom has "used" a adaptation of the Magneto Speed can speak to.

At the 2015 or 2016 SHOT show (cant remember) I spoke to the MS folks about the shift/harmonics that the MS causes, and why not build an mounting/adjustment rod as suggested in this and other threads?

Instantly and with authority, I was told that the shift/POI is partially caused by the muzzle blast conflicting with the actual bayonet and that the alternate mounting option I was suggesting will still have the same issue with a shift/POI as if the device was attached to barrel. More so with smaller profile barrels.

Can anyone who has "used" one of these devices, home made or otherwise speak to the above?

I sure would like to get my MS back in action if the shift does not actual take place, as it is quit a lengthy drive to shoot for me, and then follow up with a second trip to shoot without my MS attached to zero and confirm drops.

I think I will cross post this to gather as much info as I can.

Thanks

I've actually shot groups at 500 with one hanging off barrels and when removed, the POI change was miniscule. I also have one barrel where the MS literally acts as a tuner when attached to a suppressor, it flat out shoots, pull it and now the gun is run of the mill. I even pulled the can and installed a brake, now good, then just replaced the suppressor with a lighter Tbac ultra and bingo.
I do understand the one application of the side mount used in the king of the 2 mile shoot, but for the most part laugh at the trends used today. I feel most just want to spend money to be cool, honestly.
Now I do need to ask, why do you need 2 trips to confirm drops, would it not be possible to pull it and try the same day? That is what I do, but I am an expert in time management.
I guess it is apparent I do not own a side mount.
Edit: On the time management thing, somedays I even carry some allen wrenches in case I need to rezero a scope.

If you want the truth from me, I don't use the Magneto. The reason for this is that, without actually using one, I feel that adding anything to the muzzle of my rifle will change point of aim but more importantly, the tune. Stay with me here. The Beggs tuners weigh 4 ounces. You can go into and out of tune with a turn of only 40-50 degrees on the Beggs which amounts to moving the 4 ounces a matter of almost no part of an inch or about one twelfth of one eighteenth of an inch. So now you tune your rifle to the velocity as read by the Magneto and then wonder why your groups are so bad with the chronograph off the rifle. I shoot short range BR and can't afford the weight of the Magneto on my rifle during a match and so I would tune with that weight and then shoot a match without it? I can see the Magneto being used to establish velocity but you almost have to disregard group size when compared to on and of the rifle. I understand the ease of use for the Magneto as compared to the setup and take down time for a chronograph or a Labradar. But the use for one ends there, for me. Opinions will vary and I'm open to criticism, as usual, except from Al.

I also used to utilize this product and can tell you that every rifle it was mounted to did experience a shift in POI. The strange part was that it was not consistent and printed in a different spot on target. My belief was that was due to the barrel harmonics not being the same from rifle to rifle, which is why I sold that and upgraded to a Labradar which has zero effect on POI.

Myself and a number of friends have both the labradar and a magneto speed, the MS gets 95% of usage from all of us, maybe more. My magneto's home is in the backseat of my pickup, the LR adorns the top of my safe.

The magneto is not meant to be mounted to the rifle and left there and definitely not meant to be installed while trying load development. My Magneto is one of the most valuable tools in my range bag. The process is simple. Develop your load using whatever method you like. Once you are satisfied with results on paper and down range and properly zeroed install the magneto, fire 5-10 rounds to determine a good average and write that number down. Remove the magneto and put it back where you got it from. That way there are no POI changes or harmonic issues affecting your load. I can guarantee you that you are not shooting a match or going hunting with the magneto attached to your barrel so why would you try to develop a load with one attached? There is entirely too much importance placed on numbers in this day and age. Your targets tell you everything you need to know.

I don't have time and funds to waste components just to verify muzzle velocity, which is all you can really do with the MS. I prefer to print them on target to verify my load and desired neck tension, while having the MV confirmed at the same time. I was taking twice the time and ammo to do the same thing utilizing the MS. If you and your number of friends are so fond of the MS why don't you sell your safe ornaments?

If I needed the coin I would. I did not say the magneto was a better product, just ease of use, or perceived ease of use. Most of us shoot suppressed and LR placement gets to be a pain, dropped shots and lost data a bigger pain.
My Labradar serves me fine in certain applications, no reason to sell it. Just not the preferred tool.

Great question. I actually developed a MS mount that attaches to the front bag clamping bar of a shooting rest. I made a few samples and scrapped them, as the way the trig works out, it wasn't going to work - at least it wasn't going to be very forgiving. Plus, I KNOW people would shoot their bayonets and I don't want the liability of impacts that close to the shooter.

My next idea was one that clamps to the stock. If what you were told is true (and it makes sense to me that it would be), then I'll scrap the whole project.

Interested to hear on-point responses.

2 companies make this type of item. David Tubb made his own for KO2M; not sure if he sells his.

I am with Milo on this. Shoot your loads, then chrono for speed. I will sometimes save 1 round from each group and shoot a ladder for speed and nodes. I may shoot a few at the beginning of the day and at the end if I have a new barrel to see if it sped up. Some of us don't have the luxury of shooting at static know distances and need verified speeds. With what I have seen of the Lab Radar in the field, I will be sticking with my trusty Magnetospeed.

For what it's worth, my rifles always shoot a little high with the MS attached. It predictable and I can hit at almost any distance, minus 2/10ths.

I suppose it depends more on your shooting discipline, when shooting f-class at LR distance I believe 2/10 of a mil is roughly 7" (if my math is correct) which is way more of a spread than I would like to see, I suppose if it were a steel target where hitting either the top or bottom edge is mission accomplished that would suffice.

Sounds like magnetospeed is sore about their product market getting whacked with a wrecking ball labradar not too long after they came out probably not even making enough to pay for r&d. I know everybody bought one when they came out and i dont personally know of a single buyer or user of one since the labradar safe ornament came out. Its pretty much useless to me once i witnessed the tune change. Dont really need a chrono very much but when i do i dont want to waste components and time just to get a speed when in the end thats all it does

 

[Milo 2.0]

Wow, so the general consensus of labradar owners is that 10 bullets, some powder and primers are TOO much to waste, but shelling out the extra 270 bucks for one is the way to go, got it.

 

[Eric Leonard]

I used to be bad and let a chronograph talk me into using a load that is not as accurate just because it was faster ,,now I work up a load and get it shooting like I want and then just check the speed with my magnetospeed,,

 

[STOMP442]

What difference does it make if you shoot 10 rounds over the Magneto or 10 rounds through the lab radar? At the end of the day you still need an accurate average velocity to make any sort of accurate range prediction. The nice thing about the Magneto is you can easily carry it with you. No need for extra cases, tripods or screens. Also, when using a public range like I do there is no accidentally picking up a neighboring shooter's bullets across your Magneto.

I can’t handle the truth.

 

[6ShotsOr5?]

I haven’t used an LR myself except when a friend that has one used it alongside while I shot over the MS. The readings were within about 10 fps, with a very consistent spread and the LR always higher. Both seem like good products to me, but my bayo has a little groove on the top now so I don’t shoot it so often any more, think I’ll stick with it.

See the extra bonus you get with LR and it didnt even cost you any extra powder

Are you here to brag about you accuracy or help the OP? Go shoot a steel match with no wind flags and sighters and come back hear bragging...

I am pretty sure MagnetoSpeed has sold a ton of product and likely doesn't care about Lab Radar. I rarely see a Lab Radar, but see MS everywhere. Lab Radar has had lots of bugs, lots of failures and was 2 years late to market. I was on the pre-order" that never happened. I also don't think 10 rounds of ammo is wasting components.

 

[Bbear]

Well, since the OP's original question had to do with the various adaptive mounting systems out to allow one to NOT mount the MS directly to the barrel, I thought I would actually attempt to direct the OP to a source. If the OP, or anyone else, does Facebook, there is a MagnetoSpeed user's group there. The main entries on that page have to do with various home-made mounting systems. Some are even for sale.
MS owners using these adaptations show no change in POI by using them.
And no, I don't have one nor use one.
