Works with breaks but as mentioned it will fray the strap if over and break vents
Now you tell me.
Works with breaks but as mentioned it will fray the strap if over and break vents
I've recently begun shooting with a brake on my new to me 7mm rem mag. i was able to throw the magnetospeed on for a couple shots to possibly confirm my suspicion. so far i've been using a crude drop chart built off data on factory ammo boxes and now a few reloads. each time i'm coming up well high (.55 mils @450). precision is good with even the factory loads so far. currently i'm reading 100-200fps higher than where i should be (3339fps with factory barnes lrx 139gr). I've had no other signs of high pressure out of the rifle or cases. bolt lift is fine and the primers are not flattened, unlike my tikka t3 that flows the primers flush with even mild loads.
i've been reluctant to shoot with the muzzlebrake and magentospeed on at the same time due to how fragile the MS3 attachments have been with my other rifles. any reason to worry about the unit itself?
will the MS3 read correctly with a muzzlebrake?
should i just be happy this thing shoots and seems to deal well with the excess pressures?
Yea I found out the hard way.
Loaned it to a buddy that wanted to test some loads i just developed for him for his custom 338 lapua and the break (a fat bastured) was too long to be able to center the end of it in the Valley of the dogleg in the MS so he cheated it forward and burnt the strap in half on my MS.
I had to figure out how to put a new trap on it.
All is well now.
Yes I even replaced it, and when I plug it in the display flashes "Plug in bayonet"Bblackaj,
That's odd,
We have shot several calibers from 6.5 cm al the way up to the 338 lapua (major blow back, even swings the lens cover on my spoting scope from 6-8 feet back) with no issues.
Have you tried taking the battery out for a min and firing it back up then?
If there are concerns with the Magneto Speed and muzzlebrake (and it doesn't sound like there should be), there are other chronograph options:
