In my own personal experience, almost any good bolt gun with good factory ammo and good optics will beat 3" or even 1.5" at 100 yards if the shooter is up to it. I quit handloading several years ago because the volume of ammo I shoot is way less than it used to be. Also because modern factory ammo is difficult to beat without considerable effort at the loading press.
Most of my experience has been with Ruger Rifles but Remington should perform at least as well. All my scopes are at least 9x and some are up to 24x. From sandbags, on a stable bench, I have only owned three rifles that wouldn't shoot 1 MOA or better (most better) and they were sold or traded. The poor shooters were a Ruger Mini-14, Remington 742, and a Ruger M77 International (full length stock).
I have had, or seen, consistent sub MOA performance from two Ruger No. 1's, several Ruger M77 sporter weight rifles, two Remington 660's, Remington 700 BDL Varmint, three Ruger M77VT's, Remington 788 and a Browning A-Bolt. I'll even throw in an AR-15!
Your PSS ought to shoot at least 1 MOA if it has good optics, a stable platform to shoot from, Premium factory ammo and a shooter behind it. Post your results here, inquiring minds want to know...
