Thread: Pressure / barrel speeds?

I broke my digi scales so I'm back on my RCBS 10:10, and after I am doing tinkering with my NEA-15 (14.5") I'm going to get another Hornady digi (might be burning a hole in my pocket from the reloaded ammo costs)

Was using hornady digis, mate compared the digi load to the beams, digi was plys or minus .5 of a grain so they are now retired

Its a pro chrony, are they known for fluctuations?

yes, I bet you can't get the same average on two different days. Or even the same day if its sunny then clouds over or vice versa.

Basicy if the screens are not 4 foot apart take it with a grain of salt.
I use mine comparatively.
Shoot a known load then test load.
add or subtract speed error of known load off or on test load.

How do you know speed then?
validate at range.

Yeah really good point, i took the average from the new speeds on sunday and dropped shooter down to match. Was a tad high at 400 yards so may have to put it back to what I had. Was bang on before.
