6.5x55 Lapua neck bushing diameter

[stubblejumper]

A friend just purchased a new Tikka Sporter in 6.5x55, and we are putting together a list of dies and components to order, but in order to choose the proper neck bushings, I need to know the neck diameter of a round assembled with recent Lapua brass. Can anyone help out in this regard?

Wish I could, but my 6.5x55 build is waiting until the new year. I'd love to see what you end up buying.

I can make one for you, don't have to just found one with a 140gr Berger in it measures .291.

Thanks Fasteel, that is .291" from one person, and a PM with .292". A .290" bushing looks to be good for either.

I had this ammo stored in the garage and have measured again and now I get .293 warmer room I guess.

Thanks Fasteel, seeing as how I already have a .288" for my 6.5x47, and a .292" for my 260, it looks as though a .291" is the logical choice.

Are you able to get to the lands and still fit the mag with 140's? I'm thinking of getting a Sporter and would like to know.

Since I don't have dies or brass yet, I have no way of knowing that.

I have some new Lapua 6.5x55 brass and loaded rounds measure .296 at the neck. You can go from there.

Just measured mine. New 6.5 x 55 Lapua brass, 142 HPBT-M Sierra ==.2955

 

[stubblejumper]

Thanks guys, apparently the newer brass is thicker.At least both of the measurements with new brass are close.

Funny I saw this thread JUST as I had finished collet sizing 100 of my 6.5x55 Lapua brass. I checked my freshly sized brass and three of my virgin Lapua brass and I found consistently .291". Just my $0.02 but figured I'd chime in anyways!

Highly unlikely. FS

Is that before a bullet is seated, or with a bullet seated? I need the diameter with a bullet seated.

.296" inserted. Last 4 or 5 rounds I loaded so far (144gr lapua fmjbt and 140gr AMAX)

.296" inserted.

That .005" difference is exactly what I am trying to avoid. I like to use the Redding neck bushing dies in order to avoid overworking the brass, and to be able to adjust the neck tension. I am looking for a difference of .001" to .002".

Ahhhhhhhh. Well I'm pretty new to this, so I think I may be out of my league here... I'm just reading calipers lol.

And I do appreciate you reading those calipers and providing your numbers.

Couldn't with mine. Well actually I could, if I used a 30-06 length magazine.

No problem, just tryin to help!
