Forster Bench rest and eldm issues

[flyfisher117]

Anyone ever had an issue like this with a Forster Bench rest seating die and Hornady ELDm?

This is my first time using a Forster die, not sure if I set it up wrong but I set it up per the instructions.

I've gotten some very slight dumpling on harder to seat bullets. Nothing like that. Looks like excessive seating force. I have to ask, what is the perceived gain from the excessive deburring? If you're making a sharp point at the case mouth it can be catching on the bullet and creating more seating force than necessary.

It’s virgin brass. I have done nothing to it except run a sizing button through the case mouth and just given it a very light inside the case mouth chamfer to make sure there’s no sharp edges.

Ok. Must just be the picture then...

Does the seating force feel excessive? Maybe some lube such as graphite in the neck for virgin brass.

You need a VLD seating stem

Nothing out of the ordinary but the die does feel different with the case aligning feature it has.

They only sell one seating stem from what I can find.

Chuck a bullet in a drill and hone you seating stem with valve grinding compound.
