Anyone here have and use the Magnetospeed V3???
I been wanting a good Chrony for checking out how fast my rounds are going as I just started reloading.. Plan is too roll my own Subsonics in 9mm, .45 .300 Blk, and Supers of a few other Calibers like.223 and .308... So, I'm in the market for a Chrony and LT happens to stock the one I'm almost sold on... Things I like about the Magnetospeed 1. It attaches to most gun (The ones I have, it will) and doesn't require being set up a few feet in front of you, kind of a pain at the range. 2. Doesn't depend on just the right light. 3. Seems like if you follow the instructions on putting it on your rifle or pistols, it'll be harder to accidentally shoot... :) Videos of it in use, looks pretty slick... I was hoping some of you actually have one or have a bunch of time on someones.... |
| I have one and like it, but it has its advantages and disadvantages. It is awesome for getting the speed of a load without having to cross the firing line which is very nice if there are multiple people at the range. It also allows you to switch between guns fairly easily. The one downside of it is that you can't do load development or sight in with it attached. The extra weight will change your POI by some amount that is dependent on each gun. So if you are working up a load and you want to get velocities for each powder level, then the old style Chronograph is the better option. If you already have a load and you want to get velocity or if you are shooting factory ammunition and you just need velocity, then the Magnetospeed is so much better. |

I have one too and if come over to the west side you can borrow mine sometime to try it. I have this and a PACT unit. only time I use the PACT anymore is for handguns. if the magneto speed is setup correctly on the barrel or suppressor you will not miss a shot due to lighting like you will with a traditional chrono
I will argue on the load development thought. I develop all my rifle loads with it. yes it will slightly move POI but if all shots are taken the same then it will move POI for all of them equally. |

The only time it's a hassle is for a rifle where your handguard is so close to the muzzle that there is no room to attach it. There's been a few times I've had to remove a handguard to get my velocities. As far as load development....that IS what I use it for...I just don't do my final zero and chrono at the same time. |

I just purchased a V3, and had my first range session yesterday with it. I was on the fence at first about purchasing one, because of people saying it's not good for load development because it hurts accuracy and poi. I saw one on sale during valentines day and got it for 289 bucks.
Had a great session with it on the ar15, and had no issues whatsoever with the V3. It did change poi about 1/2" low and a little left at 100yrds when comparing with it attached and not. Accuracy did not suffer at all, and I actually shot my best groups with it attached. The display was easy to read shot after shot, never missing any of them. I used a 9 volt battery cause that's all I had, and you can check the battery voltage on the unit. After a 3 hour session with it always on, it shows the voltage as 8.3. According to manual the 9v are to have about 18 hours of run time, and the CR123s 50. Here it is attached Attached File |

I have the rail adapter but haven't had any luck with full size or sub compact glocks with it |

OP: Love my v3. Tested it side by side with a labradar on the same rounds. Highest reading deviation was 7fps on a 2750fps rifle round.

Yes, easily. The V3 comes with differing sized spacers to help you the bayonet to the desired distance from the bullet's path. They recommend 1/4" but I use it with no issues at 1/2." |

I also have a V3, but would have a lot of trouble getting a reading, if at all, with that much spacing, even with .30 cal. I generally have to set it up where the alignment rod is 1/4 to half way up into the bore line to make it work. CR123 battery. |

Worth every penny. You can still do load development, just be aware that when you find your load you will need to zero. It will drop your poi a few tenths of a mil depending on what you are hanging it from. But it won't affect your groups adversely. Crazy. I just experienced this this weekend. Groups were great just about .2 mils low from my zero the weekend prior. That being said the V3 is worth every penny in my opinion. |

What about the sport version? any difference in performance? Is the difference in price just bells and whistles, or is it something more? $160 is a lot easier to eat. There is no difference in performance in terms of accuracy. The main difference is that the lower cost of the Sporter gets you a smaller display that requires more scrolling screens to see all your data, where as the V3 allows you to see more data at one time. Also there is a slight difference in how they attach which is apparently why you can't use the picatinny rail adapter for the V3 on the Sporter. |

Also the v3 comes in a hard case and a few more things too. I don't think the phone adapter works with the sportser either but I could be wrong http://www.magnetospeed.com/products/chronographs/#accessories |

Funny you say that, I don't think I've used mine in a year.  I've just got into reloading and I only really wanted it to test Subsonic loads (.300 BLK 220 Gr, 9mm 147 Gr, and .45 230 Gr) for my Cans... After I get a recipe for each down, its not like I'll be using it weekly.. Dang it... . |

Now you guys are making me re-think the expense...

I ordered the rail mount for mine, or would this not work on your rifle? |

I called Magnetospeed before ordering mine from LaRue and the said the rail adapter only works with the V3. So I ordered the V3 so I could use the rail adapter on my PredatAR the OBR I just use the Strap and spacers. |

Good news for anyone trying to do load development/OCW with a V3 and a suppressor mounted on a 7.62 tOBR: using the rail adapter and a YHM riser/extension, I just got the Magnetospeed working without touching the barrel, and a suppressor cover even fits underneath it (which definitely changes POI and seems to affect group size too). The part number is YHM-227A, and it bridges long enough from a long handguard to get the Magnetospeed in front of a TranQuilo. It works for me with sensitivity at 9 directly on the end of the riser, but I can get the sensitivity down to 3 if I clip a rail segment onto the end to get closer to the bore (but no room for suppressor cover). Any length past the handguard can be accommodated as YHM makes rail segments up to like 12" to go on their round handguards, so shorter handguards and longer barrels can be worked with too. Using two pieces like that, the Magnetospeed is the same distance from the bore as if it were mounted directly to the handguard. Otherwise it's 1/2" farther. Midwest Industries makes an intereting looking low profile Tavor riser that would only be 1/4" farther from the bore for shorter setups vs YHM's 1/2", but it's more expensive.
ETA: Since the YHM riser is 1-piece and slides over the rail, it requires a lot of tension on the cross bolt to clamp it securely. As such, it's easy to round the allen sockets in the included button head bolts, and it's intended for semi-permanent installation. I wrecked mine after only about 5 times on and off the rifle and had to Dremel a slot to get it off with a screwdriver. I'd recommend picking up some 10-32x1.25" socket head cap screws as spares so you can get some pliers on them to get them out if the socket strips. |

Interesting... You have any pics of your setup??? 
Here's the setup if you add another rail segment. No cover, unfortunately, but you can extend it out as long as whatever rail you can find, plus you're 1/2" closer to the bore than with just the riser. This works on sensitivity 3, which has no amplification or extra battery drain. I used an extra Larue rail for the tOBR. 
And here's the sexy beast without any of that. The bipod does fit easily on the rail behind the riser.
