I actually have another 28 nosler barrel for the rifle too at 24" but that's the longest hunting rifle barrel I own. So it's a 3 barrel rifle.That 300 PRC/Win Mag is an interesting idea. Seems like it would be brutal to shoot in a rifle that's going to weigh <6.5-7 lbs. Are you running a suppressor on your rifles? I haven't shot a lightweight rifle with a suppressor, how is the recoil MNTC?
I have an 6.5 SAUM with a 22" barrel and love it. Like you said, probably will never shoot a rifle over 20" anymore. They're the Sh*t!
