Ive nearly amassed all the components necessary for the trip to my gunsmith to have my 1-8 twist 243 put together. Trying to be prepared, I want to order at least 200 pieces of brass. I've worked with lapua before and it's damn fine but I ain't scared of sorting winchester flavor and save some coin. Thoughts?
