Birthday yields Lapua Brass and a question..

[TaterInTheSouth]

With .308, Have You found the need to drop the charge more
Than a grain when work’en back up with Lapua From Winchester?

The wife did good this year, scored a new pair of Danners too.
TIA

Drop a few samples of each on a scale and get an average weight.
If the Lapua is lighter, use your regular charge or work up from there. If it is heavier, drop back and work up.

Thanks Rafael,
Yes, Of this I am aware. Just thought I might shorten my ladder a bit.
My Win brass averages 157.3 grains, The Laupa around 173.5 grain.
I was under the impression it was a given that Lapua had less
case capacity. Just thought dropping a full grain might not
be enough.
Again thanks

I bet someone who knows the volume differential will chime in.
I never played with Win so I am if little help.

Dropping 1 grain is about right. I believe the exact figure is .8 grains.

Thanks everybody.

918v, Thanks my friend, I was second guessing myself.

264win, I think I’ll keep her. Last Christmas I found 16 lbs. of Varget
And 8 cartons of primers under the tree. She is very resourceful.

Thanks again everybody,
Tater

It sounds unscientific but you could load to the same place in the case with the same powder and work from there. Lapua brass is so hard, you can load it hotter ie same charges, than Win. if you wish to. The case is the weak link and now your weak link just got stronger.

glad to hear the 308 Lapua is hard. I have had some 7MM Mauser and 30.06 Lapua that was very soft. One load was all they were good for.
