Thread: Issues Seating Cast Bullets

Hi there, for cast bullets you want that oversize as you need the bullet to fill the throat/ball seat or what ever you want to call it.
That is the important part to stop gas getting past the bullet causing gas cutting & a leaded barrel.
The barrel will sort out any sizing needed further down.
The problem you have is like the others have said, you need an M-die or similar to flare the neck & allow easier seating.
I've been making & shooting cast for 35 years so I do have quite a bit of experience with them.
Have won a lot of NZDA shoots using cast 30 cal so they are worth persevering with. Just have to have the patience to work through it with them.
Good luck.
