Thank you Sir! I recently found a great deal (though not inexpensive!) on a Fierce Edge in 7RM. I sold my '06 and 338 in order to get it! ha However, the rifle is made in "Utah", God's Country, My Part of the Harvest Field! I've had a couple CA Mesa's too, also made in Utah. But I like this Fierce better. So far, I have had to "up my Handloader Game" with better Dies, Brass, etc. ha Right now I'm using RS Grand with the 175 NPT. Its an 8.5" twist.
