Reduced case capacity by 4gr but load densitys are still the close to the same. That doesn't seem to valid when a 300 Norma has an h20 cap. Of 103 gr and pushes a 230berger around 2950fps with ~85 gr of h-1000 and a 30-375 has an h20 cap of 99 gr and pushes the same bullet around 2900-2925fps with ~81-83 gr of h-1000. Wouldnt load density be near identical? And wouldnt a rifle and cartridge case at an inclined angle not have a more consistent ignition than when shooting prone and the case is on its side with powder settling towards the bottom against the case body with air space up top along the case body? Then again it seems irrelevant when you are running at load densitys over 95% which I believe both of these cases can achieve with ideal powders. My numbers may be slightly off with the 30-375 ruger as I've never loaded for one but they are close. I do know when I was shooting my buddy's 300 Norma last week in the Texas Hill Country at angles there was no lack of accuracy out to 1200 yards even though these were not Rocky Mountain angles I don't think it would be a huge difference. Reloaders have Peterson, lapua, Norma, and Bertram brass for the 300 Norma. They will most likely only have Hornady brass for the 300 PRC. Hornady does manufacture affordable accurate factory ammo. It would be a slight step above the 300 Win in factory offerings but overtaking the 300 win to make any real ballistic difference would have to be ~900yards and further. At that point a high degree of accuracy is needed to harvest game. Accuracy that is usually only achieved by hand loading which Hornady brass has not been ideal for in the past. But who knows if Hornady markets the 300 PRC like they did the 6.5 creedmoor it may sell more than the 300 win mag or 300 Norma ever did. Regardless if it really is a huge advancement of what's already available or not.
