Coyote,
I have both and they are two totally different animals. 120's in my 7RM is not an option. Throats way to deep, Besides with the case capacity of the 7 Mag it's better suited for heavier bullets anyway.
Spicing up the thread with the comparison doesn't bother me and adds other things to discuss but I think all of us know that case capacity trumps type of caliber in this case especially, Trouble is I don't think there is any way I can chamger 7 Mag brass in my 280 Ackley.
