So I am having an unusual reloading problem that many of you may know the answer for. I had new lapua brass in 6.5cm. Turned the necks about down to about .0132. When i went to reload, Tumbled, annealer, sized in Whidden custom die with .288 bushing. So I went to seat the bullets, I use a hydro arbor and noticed the psi was off the charts. So I checked and almost all the brass I sized the necks were .288 at the very top near the mouth, but in the center of the necks were anywhere from .265 to .270 which explained my extreme seating pressures. This is very strange to me and I have never seen this. Almost like the brass on the necks got “sucked” in from firing, maybe? Has this happened to anybody?
I also noticed it happened to some Hornady brass, so not lapua specific. The only thing I do know is if may be it only happened to my neck turned brass? I had to run all the brass through the expander die and then resize to fix it all. But this will ruin the centricity of my brass, won’t it?
