Lapua 6br brass

What is the difference between the brass in the cardboard box and the brass now available in the blue box?

In a nutshell it has a slightly thinner neck

old cardboard brass had 13to13.5 walls new has 12 to12.5 walls personally i think new brass weights out better than old my 2 cents worth thanks alan.

So the new brass will work fine in a .272 no-turn chamber?

 

[dreever]

Yes it will work fine in your .272 chamber.

Very informative Fred. Nice work.

Thanks for the replys. I'll stop looking for the older brass now and just go with the blue box.

i have some old cardboard box and some new blue box and other than having to use a different neck size bushing they both do well. some seem to think the new is no good, am i missing something?
