Brand new Lapua brass
Brand new RCBS FL die, cleaned
First time using Imperial wax instead of One Shot
All my previous experience has been with Rem brass, lubed via One Shot, using RCBS X sizer die. There was a lot more resistance with the Lapua brass and regular die than what I've experienced with Rem brass, X die, and One Shot.
Die was initially set up per RCBS instructions. Got to sizing and noticed a "ridge" at the neck/shoulder junction. I could see it, and feel it with my fingernail. I took the die apart, cleaned it, lubed up a few cases with One Shot and got the same results. I then starting playing around with different positions of the die, going in an eight more turn, backing it out quarter turn, etc. Still got same results.
This picture is when I had the die backed out a quarter turn from contacting the shellholder. This moved my "ridge" up onto the neck. Looks like material is being shaved off the neck. You can clearly see the distinct line there.
What is specifically causing this? I didn't notice anything out of the ordinary inside the die when I had it apart for cleaning. I also didn't notice a pile of brass shavings.
Is it mostly cosmetic? Would you proceed to load these cases up as is? My intentions are to FL size this new brass, load up and fire, and start neck sizing thereafter. I will get into the nitty gritty load testing once I have fireformed and neck sized brass.
Thanks.
