.308 redding neck bushings

[n2extrm]

Having a problem picking out neck bushings for my .308.Ok I have read the info about measuring the loaded case and subtract .001-.003" to allow for the brass to spring back. Then I went to Redding and see the list of bushings for a .308 and they are way bigger then what I came up with here. The cases are Black Hills fired 2x and full size reloaded with a Dillon press. Sierra 168 Match kings, and I come up at .332 to .333 inches. They say range is .335 to .343. So I loaded a couple of LC cases and well still a little off, .336". So I would need a .330" for the Black Hills stuff and .334 for the LC. Does this sound right? What is "better" a little tight or loose?

My buddy uses a .336 for Lapua brass with good results. I don't know if loose or tight is better.

I use a .336 bushing for my,.308 win special match) chamber.
ID of chamber is .338, and neck tension,difference between resized brass with no bullet and seated bullet) is 0.0015 which gives me .3375. I dont turn neck because I have not found any accuracy improvements in the barrel.

IMO a .335 is too tight and makes seating difficult, And with a .337 I can spin the bullet off almost by hand.

I use this resizing for 175 mk and 155 scenars into lapua brass.

I don't know if loose or tight is better? That is a loaded question with many possible opinions. There are many books on accuracy reloading you could look up and form your opinion.

That's what I am afraid of too much tension. I think I will order a .336 and a .338 and see how they feel.

I use a 335 with Lapua brass and 168/175 SMKs and 178 AMax. Works great!
