Lapua 260 brass neck thickness

[djtjr]

Subject says it all need to get a bushing and I forgot to mic my necks before I left my cabin. Anyone know the neck thickness on their lapua 260 brass not 308 necked down or 243 necked up just the 260 from the factory?
Thanks

Sorry guys for clarity I mean neck wall thickness. I will double that number add .264 and subtract .002 to pick my bushing.

Last batch I did for a friend had 15 thousands neck wall thickness and .294" loaded neck with 123 grain Amax's.
On these, they came from the factory with .2905" o/s/necks - a little tight, so I ran them over a K&M expandiron and then through a redding bushing neck die with a .293 bushing. sized necks came out .2925"......just about right.....cases looked great BTW

I'd get a .294 and a .293 bushing for it

mine range from 14.5-15.5 thous. its alot i know, which is why i turned the necks to 14.5 and use a .292 bushing.

Just received a fresh box of 100 in 260

I mic'd 10 and all were 15 thousandths of an inch.

I am going with a .293 bushing for my gun.
