Metering and Progressive 6.5cm

[Sincerd]

I suppose this could also apply to 308. But it's pretty easy to find out characteristics of powders, but I haven't found a easy way to figure out how well a powdered meters. Specifically on fully Progressive cylinder Style powder drops.

I figure most here probably Trickle, anyone here going full Progressive after load development? What powders are you using? And what have you found success with?

The slower burning the powder the larger and longer and bulkier the rods get and the worse it measures based on volume.
Mitigate volume differences with ball powder but the trade off is you then generally induce temp sensitivity.

Or weigh off press and use a powder drop through die and get the best of both worlds.

Suggest ball powders - TAC for one - to load full progressive on Dillon or similar.
