Just my opinion, but you don't need a "magnum" to accomplish your goal with this build. I do have a 22" 28 Nosler running 195 Berger's at 2850fps with h1000.
I also use :
7-08 with 16" barrel
a 7mm Mauser with 20" barrel
and a 280 Rem with 20" barrel
To practice and hunt out to 1000. What I get out of these is less powder, more cost effective practice, cheaper brass, better barrel life, and I only have to dial or hold a couple more mils as the biggest cost.
Everyone will give you a different opinion or suggestion. There are so many options and most are effective. Good luck
