Just did up a batch of one hundred .243 Win. for my wife for killing zombie pumpkins this weekend. 75g hollow points that should chrono around 3100 f/s. Should work pretty well on those evil things. I have to say, I love the Giraud Trimmer even more now. Took about 5 minutes to change from 223 to 243 heads and adjust and about 7 minutes to leisurely trim and chamfer all 100 rounds. What a time saver. Now to do up enough .45 to start a small war and we will be ready. Hope to see some of you up in NH this weekend.
