Twist - Despite marketers hoping no one will actually do some basic math, you need NEITHER a hotrod cartridge, not a faster twist to properly stabilize the 150gr SMK with it's 1.480" length.
Fired from sedate Creedmoor velocities in a factory twist, you are fully stabilized and getting every drop of potential BC from that bullet.
MV * 720 ÷ twist =RPM. So for the Creedmoor 2400 *720 ÷ 8 = 216,000RPM. Remembering that while velocity decays quite rapidly, rotational decay is extremely slow. This means that as the bullet slows during travel, the RPM relative to it's velocity has increased; meaning more rotational stability. Buy what you want to buy, but don't do it because a schmuck at the ad company said you had to.

Bullets - Again but what you want to buy, but don't think it takes magic. I've been shooting to a mile with 140gr CC's in a couple Creedmoor's, and 175s in a 308 for many years now. As long as you have a scope you can dial, and know your drops; it's not that difficult. Since the military paid Sierra to look into creating the 175 SMK( because apparently simply reading McCoy's book was to difficult) it's been known that as long as you stay with a 9° tail angle and don't get silly with the Center of Gravity/Center of Pressure; any bullet will safely cross the trans-sonic region with the pointy end aimed the correct direction. Many of the various extremely long or low drag bullets on the market have a CG/CP issue. So while they fly like a hot-dam supersonic, they do weird things when crossing. Keep that in mind when choosing your poison.

Cheers
It might be well worth the price of a plane ticket just to watch as you do that at a mile with those guns.
Getting it there is one thing, hitting something is another. lol
