Lapua Brass not growing/needing trim

My 6.5 Creed brass won’t grow to even minimum trim length. That’s with 5 firings or so already. Minimum is 1.910 and I’m stil at 1.905.

This caused me a pretty nasty carbon ring in my opinion with it being short.

IT WONT GROW.

Mine is 6.5cm as well. Mine stretched a little at first. I trimmed to 1.910 and they haven’t grown at all. I thought it might be a good thing as far as brass life but not sure.
 
I’ve only trimmed my 6.5cm Lapua once in 9 firings. Finally starting to feel the primer pockets loosen up but should have another 5 loads in them.

Had to trim Hornady and Norma/Prime brass every 2-3 firings.
 
Drag an expander ball through it using a standard FLS or >=0.003 FLB if you want it to grow so you can get max length. Otherwise, yeah pretty standard. You will see some variations between individual pieces of brass so make sure you keep checking them.
 
Lapua brass won't stretch like Hornady's and other's
Make sure you bump the shoulders back .002-.003 every time or two - ( important )
and check length at first, to get the few odd ones.
I do anneal every time.
I think I've had 15-20 loads on mine and only trimmed once. Good stuff.

Do you neck turn Lapua brass? I just fl resize with redding type s bushing die with .289 bushing.
 
I have in the past. Now with some smiths chambering NT , "no turn" chambers
it's not needed with some of the higher end brass (Lapua, Alpha and maybe a few others )
A FL bushing sizer won't FL size the entire neck. It will leave a very small amount
just above the shoulder neck junction that the bushing will not size. Only a FL non bushing
sizer will size the entire neck and bump the shoulder back all in one stroke.
I've seen some really good shooters not neck turn and get really good results.
If you shoot 600-1000 F-class or Benchrest, then yes, if your an average shooter
then no. If you have never done it and use good brass, then don't unless you
feel it's needed. Cost's a little up front and time to do it right.

Necks not growing is not a bad thing, just don't over trim the first time. For all that say no growth, make sure your sample size is sufficient, some slip through the cracks, even from the same lot. Consistent lengths are key.

You can order a FL sizer from Forster prod. and get it with a .289 neck. ( you can order any size you want )
Helps with any run out you might have. I have them for all my calibers.

@Ranger188 I was looking at Forster dies and they say a measured case - 0.004”. I believe the Redding type S instructions are measured case -0.001”. Do you follow the forster method or redding or one of your own methods? Btw are you the same Ranger188 on the 6.5cm forum
