REPLY: My group size says it all. Remington’s quality issues are a thing of the past. Don’t you fix the problems in your world? This group is done with the STOCK rifle. Remington 700 heavy barrel, stainless, 7mm Rem Mag, Leupold VX3i 8.5-25 x 50 LRP, Nightforce Direct Mount, Hornady ELD-match...
My 300 RUM is a 26” with 3,200 FPS at muzzle according to Mr. Chrony. I’ve nicknamed it The Tenderizer. A shorter barrel might have issues with burning all the powder before bullet reaches muzzle especially since case is so large holding a good amount of powder. I use 81 grains of IMR4350.
