Chronograph purchase.

[Triumph045]

I’m thinking seriously about buying a decent chronograph for load development of calibures from .223 R.E.M. upto and including .338LM. I have very little experience or knowledge of chronographs, and would appreciate any thoughts or advice on do’s and don’ts, as well as good makes and those to avoid etc.

Many thanks

Good makes are Labradar, Magneto speed and Oehler 35p, I have all three.

The only two you can use for load development on from start to finish are Labradar and the Oehler. The magneto speed is very good and easy to set up and most importantly accurate but it's proven that if it moves  a fraction it will change your POI. The Magneto speed is very handy for verifying speed,  ES and SD after initial load development, some however will disagree.

The Labradar is very easy to set up, very accurate, but expensive.

The Oehler 35p was the benchmark in chronographs for many years. Very accurate but can be a bit of a nuisance to set up, although I found a very easy method.

That would be the only options I would choose from.
