300 prc & 375 Ruger

Is the 300 prc really just a necked down 375 ruger? I hear on a lot of pages that the prc is 'based on' the ruger but I would guess that means they are close. However I suspect if it were the same just necked down, I would have read somewhere that was the case. Anyone know the diff? Only some of my reloading books have the 375 ruger, and none have the 300 prc.


375 Ruger is a very interesting case that has become the parent of many other cartridges. I shoot it in a Rem 700 custom 7mm Long Range Magnum (Gunwerks' wildcat design).
Modifying the case is fairly simple - you just have to be patient and reform the cases s-l-o-w-l-y.
While many comment, "why do something the 7mm Rem Mag does well," it'll send a 185gr projectile at 3000 FPS, ~300 FPS faster than the 7 Rem, using 20 grains less powder than the 7mm RUM and 2-3x the barrel life of a 7RUM.
