100% agree.Keep the 30-06 and spend the money on a trainer rifle, something that you can send 1000's of rounds down range and learn as much as you can. Put the same scope you'd put on a larger rifle. If you aren't confident past 400 yards, a larger caliber won't get you to 700.
Put money into a trainer rifle. Then start dry fire practicing from realistic positions, like you’d find yourself in while hunting. Followed by shooting from those same positions, using a trainer rifle, to verify accuracy/precision. From my perspective, shooting 20-50 rounds a year, isn’t going to increase your ability with a rifle much at all. However, dry firing and shooting 1,000’s of rounds will teach you a lot about getting in/out of shooting positions, tighten up your wobble zone and will develop marksmanship.
