Caldwell Ballistic Chronograph ~ $75 and has a good app for the iphone/ipad
Magnetospeed Sporter ~ $180
Magnetospeed V3 ~ $380
Labradar ~ $550
Lots of options across a wide range ...
I used a Shooting Chrony for many years before buying a Magnetospeed. I also have a Caldwell for use with handguns; it's easy to set up and works well enough for the task.
Like murf, I too have used a Shooting Chrony (F-1) for twenty-some years. My wife bought it for me for Christmas one year. I don't know what she paid, probably well less than a hundred bucks back then, but I've used it for measuring the speed of everything from pellets out of my pellet rifle at 500fps, to bullets out of my 22-250 rifle at 3700fps.
It kind of depends on your situation though BigDog 1955. I do most of my shooting off our rear deck, or down at the county gravel pit. I can reset my chronograph, or do whatever needs to be done to it by simply walking over to it. But if you're doing most of your shooting at a regular shooting range where walking downrange occasionally is not only forbidden, it could be deadly, you're going to need something with remote controls, and maybe even a remote readout.
But as far as needing a chronograph that automatically does averages and standard deviations, I can do averages with a notebook, pencil and pocket calculator. And standard deviations can wait until I sit down at this computer and plug the velocities into Excel.
Whatever you get, be careful. Chronographs don't stand up well to direct hits. I've been lucky - the worst thing I've ever done to mine was forget to turn it off, so the 9V battery was dead when I got down to the county gravel pit. Now I carry a spare taped inside my F-1.
I am not aware of any light-triggered chronograph that has a provision for external calibration, so the number displayed will be "close" to the true velocity, but is unlikely to be the true velocity. The readings can also be affected by temperature and the freshness of the battery.
A chronograph is a useful tool for determining whether your rounds are "in the ballpark" as well as whether their velocities are consistent from round to round, but if you are expecting it to consistently show 1,250 fps each time because that's what's written on the side of the box, you will be disappointed.
If I were doing it over I'd buy this. Everything I read says it is better, at about the same cost.
I'm very happy with mine. I've tested 750 fps pistol rounds, several kinds of 22 rimfire, and some hot magnum centerfire loads. Seemed to produce believable, repeatable results with all.
The prochrony is mostly used for tuning my bows now, those shoot in the high 190s to low 300s.
If you got shot three times, you’d be cranky too
Anyone use the Magnetospeed -Sporter ? V3 may be out of my price range!! Thinking about the Chrony F1 and it looks like a hassle for me and SD wind, I have a hard time keeping my spoting scope up right on a tripod, also want to use it on my air rifles indoors.?? I haven't thought about the pistol use with the Magnetospeed - Sporter, Guess the auto's are not going to work Now I'm back to the F1??
The best part is not having to use sky screens and it doesn't care if the day is sunny or overcast. To me that's worth the price of admission.
This is where I purchased:
If you have the pic rail adapter and your pistol has a lower rail then you can make a mag speed work with it, tho i THINK it has to be the V3. They work fine on revolvers also, used mine on my ruger SBH in .44
if you're concerned about accuracy, read brian litz' test results
my experience is that i'd miss a large percentage of shots (20%?) with both CED and chrony, due to light changes or misc stupid stuff.
for the first few years i had the magnetospeed, i only missed one round, and it was when i blew the endcap off my suppressor. last year i missed a few more due to battery being too low. doh!
lots of people seem to keep a chrono a long time, even 20 years, if i considered the cost of the rounds i didn't get a reading on, the extra $300 cost of the magnetospeed would actually save me a lot of money, not to mention frustration.
Taliv, if cost were not a factor, would you switch to a Labradar? I'm happy with my Magnetospeed, but it would be nice to have something that works with both rifles and pistols and that doesn't have to be set up "down range" of the firing position. Just curious ...
i like simple and reliable
i like small and light weight, easy to keep in range bag
and i like that the battery lasts years
the potential POI shift or change to group size from affect on barrel harmonics hasn't been very noticable to me, but i'll concede the point theoretically
I never chrono pistols
