But you mean how far back should you be bumping the shoulder ENS? Do you have a bump gauge to measure or are you using a thimble type micrometer tool? .001" to .002" should be fine however it does to a degree depend on how often you check and then bump it back.

if you do mean the shoulders as dave says .002 - .004 but defintly no more than .006 as you can run in to the dangerous area of case head sepperation as dave says get yourself a shoulder gauge

Are you getting a tight bolt when you try and chamber a round?

Hi spud

Nope. Still waiting for FAC so no gun in my hand at moment only brass prep

Have once fired HPS case from firing my gun at euro using them as benchmark accepting that some springbuck of the brass may occur

I thus use them as a chamber benchmark

I now have new lapua brass I need to resize prior to neck turn

I want to do the minimal resize prior to trim and turning them

if its brand new virgin lapua brass simply run it through a full length sizing die then partial neck turn then after the first firing complete the neck turning to disired neck wall thickness and also trim to length after you have resized them in a fl die but before firing

Ok cool thanks will do so

Got the redding FL sizing die to get it to the neck shoulder joint

The bushing die dies not full get there for the neck turning

Seating and neck sizing will be on arbor press with wilson dies

If you neck turn you will probably have to change the neck bushing to suit or you will not get enough neck tension. Also it is probably best not to primer pocket uniform until once fired.
