That's really too bad given the price you pay for Lapua.
Big reason I set things up to do a light neck turning. No turn doesn't always pan out.
As long as the neck isn't under 12thou thick, it should last just fine. The Lapua alloy is quite resiliant.
Nowadays, LR shooters are annealing at 3 to 5 firings anyways no matter the brass. Seems to help with consistency and stringing. Still not sure if that is worth the extra work.
Good luck with your search. 6XC new lots are supposed to be quite consistent but they will not take the beating Lapua or Win can give you so that is another negative. Not that cheap either.
RWS is supposed to be quite durable too but have not used any.
If you are willing to wildcat, you can size down 243 and trim to length. Then you can neck turn and have a consistent 15 to 16 thou neck. Anneal and you are good to go.
Not anymore work then what you would have with the Swiss and you can get that done without huge costs or headache trying to find brass.
Start with a 7BR FL sizer with no decap rod. Push the shoulder back to the correct headspace. Trim. Then run through 6.5 die, neck turn then 6mm. Fireform and you are done.
