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.

I'd like to see some QL data for 7 rem mag using H1000, Fed 215 match primer, 160 nosler Partition, 24.3 barrel. I want the QL software but it's not yet compatible with a Mac and that's all I have access to. I believe the published info elsewhere is really quite low and nowhere near the real potential of this cartridge.
