the 28 nosler is an amazing round and was built with a 26+ barrel in mind to get the most velocity possible with the heaviest bullets possible. With the amount of case capacity it has I don't think you will ever be able to achieve a 100% burn rate of almost any powder in a 20-22 inch barrel without seeing excessive pressures. I can see how a shorter rifle in certain hunting situations would be handy and I'm not a fan of suppressors but see the draw but just think they're ugly and clumsy which is just my personal preference but to each his own. Much better cartridge choices for what you're wanting but again to each his own.
