Hey guys,

I have 300 pieces of 6.5x47 im looking to neck down to 6x47 Lap.

I have measured the neck thickness on them with a Mitutoyo hand mic (The ball and and tapered anvil type) and im getting an average thickness of around .0125" - .0130"

From memory my Lapua 308 brass was around .0145" - .0150"

Can anyone shooting 6.5x47 Lap brass confirm that this is about right for thickness? I am hoping if this is the case that once ive necked down the necks at worst might come in at around .0145" which will finish me off at .272". I will be running a .275" no turn neck reamer. This is a practical rifle gun and we shoot upwards of 200 rounds in a single competition.

Question: Is everyone getting around about the same neck wall thickness out of the box? and for those running a 6x47, what thickness were you measuring after necking down.

Thanks in advance,

I’ve got 0.2695” and 0.013-0.014 neck thickness on 6.5x47 Lapua unfired necked to 6mm brass

I will be surprised if the neck thickness will vary after necking down....keep us posted please.
