A comment by Grimmy on Friday open gun advice thread
7mm rem mag is a very good, all round choice.
The cartriges tend to be more generally avaialable than other power loads. There is a nice mix of factory loads available in different bullet weights for either long range shoots or closer ranged bush hunting. The trajectory is nice and flat for longer range shoots with lighter weight bullets, and has enough power to punch through any large game with the heavier bullet weights.
The bullet is also not so large that it tears up game unnecessarily.
Remington 700 is the rifle of choice, imho. You can also get multiple stocks for the rifle. A composite for cold/wet weather hunts and wood for good weather/ looks.
The 7mm rem mag works very well for game from the boar/deer range and up through the elk/moose/bear levels.
