I purchased three unopened lbs. of Hodgdon "Benchmark" powder this morning from a serious bench shooter who doesn't care for it in his heavy barreled .308 target rifle. All of my books are quite old so I looked on line to see what I could find out. It shows pretty high velocity in some of the smaller calibers. Do any of you have practical experience with this powder in the .223 and .22-250?
