Magnetospeed info displayed

[zini72]

i own a Magnetospeed V3, it works well and i am overall happy with it.
Is it possible to get it to display ES & SD at the same time?
it is an inconvenience to go back through the menu and switch back & forth.
Thanks,

The answer to your question would be , No . They give the S/D per shot , or group of shots , and then the E/S number follows . It's the way it's made .

Get the XFR app/adapter if they're still available. Works well as I remember.

The SD/ES field is an OR setting. That field can show ES or SD, you can pick it in the settings menu, but there's no way to have both on the same screen.

I pick SD because ES is not that difficult to do in your head.

I have a Magnetospeed and love it. I do not mess with statistics on the unit as I take my data home and input Mv range in EXCEL and do a curve fit with ES and also get SD as I calculate them on my HP calculator.
I use that data to find the best load for lowest ES . This negates fiddling with seating depth as the curve fit function allows a very good curve that I use for lowest ES.
Folks don't realize, that fiddling with seating depth does the same function as my method. Adjusting seating depth is simply changing the case volume. I have experimented with QuuickLoad and found that tweaking load is just as accurate as changing seating depth. I test 6 5shot groups with ~1% steps and this gives the same change in Mv as changing seating depth in 0.005" increments.

The statement that changing the seating depth is just changing the case volume is interesting. I think what you are saying is that you can create the same velocity curve in QL by changing either the case volume or the seating depth. I’ll take your word for it, makes sense to me. I’m not sure this translates to accuracy changes though, and I don’t think QL can predict those. I think there are multiple effects going on that impact the accuracy, and some of them are not controlled by internal ballistics, such as the compressional and shear waves in the rifle as per Chris Long.

I’ve you archive the series and then view the archived series, it shows both Sd and Es on the device screen.
