Andrew,
Do you know the know the dimensions of your chamber? if so it would be that less 1-3 thou clearance plus what ever tension you like to run.

Hi Andrew
Presume you want the bushing sizes to suit the Lapua cases. I use around 248 or 249 for Lapua cases. Some people use 247 for slightly more neck tension. When the necks thicken up a little you can even get by with a 250 bush. If you are going to use an expander button probably go with the 247 as that will also take some thinner necked cases (eg Remington) down just enough as well.
Regards Malcolm.
