Bought a new X-Caliper barrel for my 22-250. It's an 8 twist so I plan to load as heavy as I can, so brass life may be an issue.

I'd like to headspace it using new Lapua brass and a couple of layers of scotch tape to get a good tight headspace and try to limit case expansion/growth.

My question is; how tight is tight enough?

Thanks for any advice or experience you can lend.
