300 Norma Mag

Going back to sizing dies, my LE Wilson sizer will not allow me to bump the shoulder at all. I use Redding comp shellholders and screw the die in to make contact with the shellholder well before top of stroke to avoid camover. Even with the standard shellholder (+0) I’m not getting any bump, and cannot size brass fired in a different chamber to fit mine at all. I’m going to call them Monday, but what other issues have you guys found?

In my 300 norma improved i had to take a shell holder and grind it off about 8 thousand. I just took a diamond stone to shave off what I needed

I wonder if putting the die body in a 6-jaw chuck to take about 10 thousandths off the bottom would be accurate enough not to affect runout. And I wonder how hard that joker is…

I always did the shell holder if you mess up its cheaper lol

I think Lapua 300 Norma cases is really tough imo. I have to run the ram twice to get the bump on my bullet central sizing die. I found that was working for me.
