6 Creedmoor made from Lapua 22-250 brass

[brianc74]

I am wanting some advice and tricks on converting Lapua 22-250 brass to 6 Creedmoor brass. Are there any cons to doing this. This is in a full custom bolt rifle. Built with a tight chamber throated for 105 Berger hybrids.

When forming into 6.5 Creemoor I lost about 0.023-0.026" neck length and the necks were thinner than I wanted (I can't remember the value). However, I would expect more acceptable brass forming into 6mm as I don't think you would lose as much neck length (if that is even much of a concern to you) and the neck walls should be thick enough to still perform a neck turning 'cleanup' operation. I would wait on Lapua 6.5 Creedmoor brass if that is an option for you. I am waiting on a 6 Creed reamer and if I Lapua factory brass (6.5) is still too far out I will neck down some 6.5 Creedmoor cases I converted from .308 Palma brass that I have in the que. That route is more work and definite turning required but you get the small primer pocket without waiting for Lapua to ship the new 6.5 Creedmoor brass.
