I'm sure this is already answered somewhere, but I can't get the search feature to cooperate. I'm getting ready to start my first batch, and I've read that I should start 10% low. Is that 10% lower than the max, or 10% lower than the recommended starting charge? I'm assuming I should start at the recommended starting charge, even with LC .223 brass (thicker, less volume, more pressure), right?
Thanks for putting up with all the questions lately.
