Mark, I shoot 1000 yard BR. I have shot rifles in matches with less than 30 rounds on them since build. If you can develop a 3" at 1000 yard load in less than 30 rounds, surely you can get a rifle ready to hunt in less than 50. The ballistics software makes building a dope sheet take 1/3rd of the ammo it used to take.
My long range hunting rifles that I most often use are my 7 Rum and my .338 Lapua. Both had 800 yard dope sheets ready in far less than 50 rounds.

I am sure Nosler did not design this cartridge to plink with.

Jim, it does not take a lot of practice with a particular rig to be proficient at shooting it. I rarely shoot my hunting rifles. I shoot my Sniper rifles regularly as well as B.R. rifles. I hardly ever shoot my hunting rifles. I drug my 7WSM out this year. I ran a dry patch down the barrel. I shot 1 shot at 300 yds. as a fouler. I shot another at the same target about 1 hour later. They were less than 1 1/2 inches apart. Rifle is ready to hunt.
