/\ /\ This /\/\Did you prep the brass? Chamfer ?
We are on the same pageJust shoot the cases in your chamber to fireform if you will. I bet your neck tension will be normal on second loading. Seems Lapua always has very tight necks on first firing. Easy peasy!

This very well may be because the dies is not sizing the neck of the virgin brass because the virgin is already less. One gentleman bumped on this but that would support the fired vs virgin. Fired brass typically has a little powder residue still in the necks for a little lube, virgin and SS tumbles are very grippy.I took some 1x fired and they loaded like butter.
Did you anneal yet ?Here are the measurements…
virgin brass
Neck ID .260
Neck OD.2885
virgin brass FL size
Neck ID .261
Neck OD .2895
2x fired brass
Neck ID .265
Neck OD .2945
2X fired brass FL sized
Neck ID .2615
Neck OD .288
I guess the big question for me is what changed? The first hundred brass that I did I had no neck tension issues. Now all of a sudden I'm having neck tension issues. It's like I set up the dies wrong, or the expander ball inside the dies got worn down which doesn't seem possible.
I was wondering if the brass has lost toughness and become cold worked but 2x doesn't seem like it should already.Did you anneal yet ?
Yeah, I know, .....doesn't seem like it should really require annealing a 2x............unless the loads are towards the hotter side.....more heat.......more brass flow.I was wondering if the brass has lost toughness and become cold worked but 2x doesn't seem like it should already.
