I had an issue while working up a load that I've never come across and thought I'd ask for some help.
I am using new Hornady brass and Barnes 168 TTSX bullets for my 300 WSM
I am full length resizing with a lee die.
I am using imperial wax
I resized the brass, measured length was right and chamfered in and out.
I then primed, charged and started seating the bullets with a lee die.
The goal was 2.860" and I getting the die set walking in the COAL when I got to 2.870".
The next little twist the bullet went to 2.850 so I used my bullet hammer and backed the bullet out a hair then backed off the die and repeated.
I got to about 2.870" and then the next adjustment it jumped to 2.850"
I tried a different case and bullet and the same issued happened.
I then examined both bullets and I could move them up and down in the expansion ring/cannelure on the bullet.
The lip of the brass was in the cannelure.
I pulled the bullets, emptied the brass of gunpowder and de-primed all my brass.
I figured that I must have done the resizing wrong.
I pulled the die apart and cleaned it.
I reset the sizing die with a 1/4 twist past it touching the ram, locked it down and double checked that it camed over a little.
Okay I thought that should fix it and resized all the brass.
This time before I primed the brass I took two brass randomly and tried seating again and the same problem happened.
They can be slid back and forth in the cannelure.
I am not sure what I'm doing wrong what do you suggest I do?
Cheers,
B
