Fire-forming Brass

There is no right answer for your application, you need to find it your self.

That you don't know a right answer here doesn't mean there isn't one provided otherwise.
Do you need a consensus to see it? Can you find it yourself?

I would like to know the weights of the Winchester and Lapua brass. If the Lapua is significantly heavier, it has less volume, and putting the same weight of powder in both will produce more pressure in the heavier cases. Back in the day when we were shooting military brass a couple of calibers, this was common knowledge, these days, not so much. Do you have any of the Lapua brass left? If you do, trim one and a Winchester case to the same length and weigh them. I would be interested in the difference. Also, you could do a water volume evaluation, just make sure that they are both in the same condition as far as being fired or not.

Brass gone. The load was worked up in the Winchester using a chronny. The same procedure was used in the Lapua brass and turned out to be the same amount of powder. The head expansion on the first firing was greater than expansion on 9th fired winnie. As a side issue to this one I have had Winchester cases separate on second firing in another calibre because the metal used could not be called brass it was such a poor quality and minimum size in a max sized chamber. There is brass and brass then there are sizes and sizes. I have learnt more than a little since I started reloading in the late sixties early seventies when advice and knowledge was short or wrong. My Chronny became my best friend.
