Re: 7mm Mag or 7 RUM for OCT 12 Guns, 2 Choices
I know that you've said either 7 Rem or 7 RUM... but there are much better choices in readilly available chamberings. I think of how you want barrel life and performance. you can get great performance out of both the rounds you mentioned, but you can get the same performance or better, with better barrel life.
I am mainly thinking of the 7 RUM... the STW and Dakota are in the same preformance range. The STW is right on the heels of the RUM and burns less powder, with good brass choices.
As far as the 7 Rem goes... Im a guy thats not to sure how it got the recognition that it did. It performs great, but needs alot of barrel and excess powder to do so. It is the most readilly available 7 out there though, period.
The 7WSM, 7 SAUM, 280 AI or .284 win are much more well thought out cases for that bullet.
All that being said, I think that if you want to run a 195 Berger you will need at least a WSM/Rem mag case, but are looking more at the STW/RUM/Dakota class.
Im interested to see if you can run the 195's at RUM speeds in a 1-7 and not torque the jackets off.
