What is the trim to length that you use for your Tomahawk brass? The new Sierra manual lists 2.840" for the RUM, do I use this same measurement? How far should I let it go before trimming? Most of mine now runs 2.850-2.855" It's been fired four or five times and it looks like it is about time to anneal the necks. Should I trim before or after annealing, or does it matter?
