If I use Sinclair expanding mandrels to size the neck for neck tension, do they need the cases neck insides to be:
Lube inside neck? (graphite or spray – I have both)
Just work better if lubed?
Dry from tumbler is fine?
Dry from tumbler, but brush out the dust and media first?
I’m about to set up a RL550b for 223 semi precision ammo and may migrate to other calibers later. So my plan would be to do one of the following.
[*]1 FLS+decap on single stage Forster with undersized expander ball or no ball, chamfer/deburr, tumble. Then go to the progressive for prime, a no lube expander mandrel, powder, seat.
[*]OR
[*]2 Use 2 passes in progressive press only with outside lubed and inside neck graphited. First toolhead would be decap, FLS, graphite brush, expander. Chamfer/deburr and tumble brass. Prime, Powder and seat with second toolhead.
Or
[*]3 Tumble first. Single pass through progressive with body lubed, but dry inside neck. Decap+FLS with undersized ball/no ball in station 1. PULL CASE OUT, clean primer pocket, trim, chamfer/deburr, replace in station one. Prime. Then advance to station 2 for a dry expander mandrel. Station 3 for powder. Station 4 for seating. Wipe outside lube off by hand..grrrr...
