Am in the middle of reloading some 6BR. Shot 200 pc's brand new Lapua brass for barrel break-in and brass prep for load development. Brand new die with 0.266" bushing. Ran them all through once before shooting any of them just to get the necks right, so in total, only 200 pieces through this die.
Today I sized the first batch of 50 and took them to the expander mandrel and noticed zero effort getting them into the necks....there's always been a bit of resistance with the Dasher necks.
Thought this odd, started measuring....I'm getting 0.242" after sizing and mandrel "work". The mandrel is 0.242"....so I guess that's why! So I only have 0.001" neck tension?
Brass is 0.013" thick. After sizing, neck is 0.268".
0.268-(0.013*2) = 0.242" ✓
Well that seems low, so to double check the bushing, I tried taking the die apart. It's STUCK so bad it's damn near breaking my bench vise and the wrenches are tearing the shit out of the die. Nothing budges even a little bit! I've tried holding and turning it every which way to no avail.
What am I doing wrong?
I guess I could leave it as is, but I'll never be able to change bushings or clean it out. Help?!
