If you want to shoot at range, it takes a lot of practice. getting the drops is pretty easy.. but the wind is a fickle b**ch. You would have to spend some fairly serious cash to send say 1000 rds/year down range in nearly any factory round. Even if its affordable I wouldn't find 50+ rounds a day from a 300wm fun.
If I was going to start again..
Learn to reload, you can get started for maybe $200 or so. It will pay for itself in the first years ammo.
I would troll the gun shops till I found a used varmit gun cheap and then spend $350 to have ITD spin on a new tight twisted tube in 243/260/6.5CM (me I would choose the CM, because the recipe is on the box)
Then I would shoot the crap out of it.
when banging steel at 400, 500 and 600 yds gets boring.. go buy your 300mag you will be ready to make good use of it.
