Have all ways used the proper head space gauge when rebarreling a rifle however this time I want to try the 'empty case w/ and w/o tape" method.

The rifle is question is a Savage Axis in .223 and the new barrel is a .450 Bushmaster from Rhineland Arms.

Plans are to sacrifice a new cartridge (do not plan to reload) by pulling the bullet and making the primer inert before depriming. Going to use one of the kinetic pullers as not to damage the case mouth.

I was thinking about inverting the bullet and press fit it back into the case as it is a flat base bullet. Thoughts are by doing so, this would alleviate any possible neck crushing that can occur while mounting the barrel.

Thoughts anyone?
