I used the new funnel tonight. RL22 in 30-06, not a great test, because it is a short stick powder, but it didn’t bridge at all. W760 in 243, I was worried about this one because w760 is very fine. Not a single grain missed the case mouth, and none got caught between the insert and the funnel. Last was AA2230 and IMR4895 in 35 Remington. This one was cool because there is no 35cal insert, but the neck is so thin on the 35 Remington, that the 338 adapter fit perfectly. No issues with the stick or ball powder in this one either, no bridging and no spilling.
I will update as I use more different combinations. So far, very happy.
