I thought the Dillon powder funnel would flair the case end a bit? I manually measured and loaded the 50 test rounds. Next I’ll load them on the press and see if it makes a difference.
Dillon rifle powder funnels do not flair.
With the exception of the 30 Carbine powder funnel which by the way can be used with 30 blackout if you wish to flair case neck this way.
I had one and sold it. I like the M Die better. Just my personal preference.
Use M dies for bulk 5.56, 300 blackout, and M1 Garand ammo.
There are all kinds of similar solutions from different manufacturers. I just prefer the M Die.
