Exactlly my worry. This is a bottle necked case. The filler is filling the 50 cal size case body and being compressed even more trying to go out the 45 cal neck under pressure when fired. I was very concerned that that the Dacron was staying intact and slugging up as it was extruding through the funnel of the case neck.

Geez, folks. All we are talking about is 2.5 Darcon for a 450/400 3 inch . It isn't burnt, consumed or melted to your case or barrel. It is just spat out the muzzle. It's a whole lot more flexable that the foam!

As long as you are using a foam or Kapok the filler is the important thing. RL-15 is position sensitive. As long as you keep it against the primer you will be rewarded with some of the most uniform velocities you will ever get out of your double!
I have used Dacron filler with RL-15 in bottle necked cases for 450/400 3 inch, and 475#2 Jeffery. I have only used the filler with RL-15. I've been using it for 7 years now. For me it's easy and it works! Just my opine!
