A mate and I have been throwing around ideas for .257" projectiles.
I was thinking 17HMR brass but to expand the brass may be more that I want to go to, so what about 17WSM brass?
I am comfortable with annealing and drawing it down, we have the lead wire making sorted, trimming, I have made the machines, the derimming of this brass .....I have not.
Has anybody done it? How thick was the brass? Drawings?
