Thread: Magnetodspeed "sporter" suppressor mod

Well after getting completely different velocity readings with the same load a couple days apart using my mates Caldwell chrono I decided to mod my magnetospeed sporter so I can use it with a suppressor.
I've found the magnetospeed to be very consistent across different lighting (cloudy vs clear and sunny).
I also figured no point in having it sitting in the draw and using something I don't trust,
I was going to sell and upgrade to the v3 magnetospeed but I would've probably lost a fair whack of $$$ plus had to outlay on the v3.
First up apologies I didn't take any before pics.
But basically followed a video tutorial on YouTube which I'll link in this thread too.
After scribing a line .6" around the top of the base I then used a cut off wheel on my dremel to trim the base down so the whole unit will sit closer to the muzzle line when strapped to the suppressor.
I also cut a piece of bike tube to go between the base and the suppressor as even cut down with the smaller rubber shim they come with I think the muzzle line would still be too high from the magneto ramp.
Anyway here are some pics hope it all makes sense.

Here's the link

I might have to do that with the extra blade I think I still have lying around.

I have always found the magnetospeed to be pretty consistent, hopefully I can use it again now

Not very surprising since the magnetospeed doesn't use light to get it's readings.

I have a v3 but used my old Prochrono yesterday at the range. It was a cloudy day so I didn't put the overhead screens on, most of the readings seemed bang on except for one when the sun came out, 9147fps for a 308 seemed a little bit off...

Yeah, it's a good bit of kit, without the hassle of having to recheck alignment so much between shots.

Not alignment but I used to check the strap tightness on mine for the first 3 or 4 shots. This after having mine come loose after maybe 10 shots. At least it drooped down and wasn't at risk of a hit.

aha...all is clear as mud now thankyou...

If you're not keen on altering the bayonet, adding a couple of neodymium magnets seems to increase the magnetic fields enough that it picks up the projectile passing through. Tried it yesterday and it worked fine for the first 6 or 7 shots until the bayonet moved too far forward under recoil. Repositioned it and nipped the strap up tighter and it was registering fine again.
