apples and oranges aren't they?

I think if you want to compare big boys, it would be the 7mm STW vs. 300 RUM etc...

or 7mm rem mag vs. 300 win mag.

the .300 win mag is very popular, a classic,

For a beanfield/paper/deer, I would just take a 7mm Rem. Mag., anything larger and I start thinking about elk...so if were talking beanfield/deer, no need for even the 7mm Rem Mag let alone 300WM or 7mm STW.



Not sure how popular the 7mm STW has become? will it last etc...? if you handload who cares, but in comparing the 7mm STW vs. .300 win mag, seems like 2 different style of cartridges.
