Firearm selection depends on game, terrain, restrictions, distance of shot, budget and preference.
30-30 is a nice brush gun, but terrible at distance. I honestly prefer a 35 over the 30-30 in the brush.
30-06 or 7mm can handle most terrains decently but doesn't accel at all.
Then you have severe distance stuff that I honestly think you need more time under your belt before even considering.
I personally hate Remington anything....but that's just me.
