long cast bullet in short neck

[Catch]

I am shooting cast in a Browning B78, and wondering how the longer bullets are affected in accuracy when the bullet is seated below the neck in the 30 06 cartridge. Does it make any difference if there is a gas check or not if it is a light load?

First, most cast bullet loads will not be below the neck in a .30-06. What bullet are you having trouble with?

Second, seating below the neck is not an issue in most cases. But, do not use the old Lyman slip on gas checks. Use a crimp on type that will stay attached when fired. I have a couple of bullets in the shorter neck .308 where the gas check is seated below the neck. They are very accurate.

Last, plain base bullets do just fine lubed at lower velocities. Gas check bullets without the gas check sometimes do ok and sometimes do not. Depends on the bullet and how well they are cast.
