See title. Specifically for the "high power, bolt-action rifle with a variable-power, magnified optic" mentioned in the 5 guns post , complimenting the other guns mentioned there. If you could only have one, which would it be? I know the answer is always "it depends", but what is your thought process in deciding and what works best for your needs?
.308 win
9mm, 5.56, and .308 are the bullets.
All other ammunition will be generally more expensive, harder to come by, less consistent in quality control, and will have fewer options for factory ammo.
Going beyond the big three is great if you're into handloading, or if you're so rich you need a .338 bonafide sniper rifle. Other than that, use what the whole world uses.
Yeah definitely one of the questions I had was what is the equivalent of a 9mm Glock or .223/5.56 ar15 for this type of rifle. Getting invested in exotic cartridges is not so interesting to me, I'd rather shoot what's common and leave the rest to gawk at in YouTube.
Nothing in the world is as nice to shoot as .338 Lapua.
On the other hand, it costs more than cocaine.
