Enjoyed reading this thread. It is tough deciding on which caliber to use.
I like 7mms and owned a great deal more than the 30s. Been shooting two 7mm/375 Rugers with 180s lately and believe it is one of the best 7mms I have ever owned. I have owned three 7 Rums, two 7 stws, and a slew of 7 rem mags not to mention the usual smaller ones like the 280 rem, 284 win, 7-08, 7 x 57 mauser. 7mms will recoil less than a comparable 30 cal.
After reading Skyking's thread on the 7 WSM with 180 Bergers I am very impressed.
7WSM 180 Berger takes down two Grizzlies!
However I still take my 300 Rum on my elk hunts
. It has killed quite a few elk with authority. I believe I will always have a 300 Rum in my collection.
You need to get one of each! <grin>
