I just read a thread about the hornady mix up. I might as well tell everybody mine. It's been awhile since I made up a few rounds for my 22-250 so I grabed my speer book # 12 turned to the info, pg 152, for my 22-250 and there it was tim to length 1.920 WRONG!! it should be trim to 1.902 and max case length should be 1.912 not 1.930 as stated in # 12, on page 154 it states that the max loads for a 52gr & 55gr bullets using IMR 3031 is 36gr. In the IMR handloader's guide that I have it states 35gr for 52 gr bullet and 34gr for the 55gr bullet. Know wonder I had primers popping out!!!!!
