to chronny or not to chronny

[Jennb]

I can short distance at home so I use a magneto speed to get the best ES/SD and then I load that and fine tune with seating depth at the range with no less than 300 yards.

How would this work with a muzzle break?

Its not going to be a problem having a muzzle break on your rifle and using a Magneto speed
or any other chrongraph for that matter....I use mine in that config on some rifles.
You will wonder how you did so well without it....or or not.
I test every load I use in Competition at some point ...be it after im done with load development or in the beginning....

High ES will, most of the time, alert you that something's not right in your loading process. Very low ES will often coincide with excellent accuracy, but sometimes the load with a bit higher ES shoots the best. But most guys I know that shoot past 200 yards want ES below 15 fps for five shots. You can get a Magnetospeed Sporter for under $160.00. NOTE: Since the Magnetospeed hangs on the barrel, you may have to re-tune your load for best accuracy after the chronograph is removed.
