the beam scale seems to be more accurate the more charge wieght im trying to wiegh out cause in my 5.56 its also all over the place fps wise as well . but ill deff give the scale a once over today ty for the tip
i got 10 rounds loaded for today using that digital scale so ill chrono those and see how those do
Don't forget ppv is temp sensitive as cfe223 and leverevolution.
So the fps variation could very well be the temp sensitivity of the powder showing itself.
This is the reason why I'm looking to unload my cfe223, ppv, and probably my leverevolution. I can live with a few fps less and not have to deal with that with ar-comp, h4895, h335,h322,varget,tac,aa2520,benchmark,blc-2.
Ar-comp seems to be the clear winner for any bullet in my ar grendels, except for the light weight pills, those pills I like h335 the most. Anything from 120 and up ar-comp is where it's at in my grendel ar's. My bolt grendel I'm rocking the h4895 the most.
