The 7 prc looks to be phenomenal on the ballistics side, but looking at 600 rd barrel life from what I been told. So yeah I'm not a fan either. The last couple weeks, the 300 prc peaked my interest again especially since most of my shooting with it will be long range target. What would the bullet drop difference be on the 300 prc vs the 300 WM at say 1000
Trajectory is determined by speed and bc, that's it. Bullet weight then dictates energy. The difference between the 2 cartridges, 300 prc v. 300 wm, is minimal. But factory rifles will have different twist rates which is important, 300 prc is 9T and 300 wm is 10T, so the prc can stabilize 220+ gr bullets where as the 300 wm is limited to about ~215 gr.
I need to clear up some b* I see here, the 7 prc is in no way a barrel burner, someone lied about a 600 rd barrel life. 7 prc is nothing more then a 7mag upgraded without a belt, steeper shoulders and long neck, all the bells and whistles of a modern cartridge. And should get average barrel life of ~1200-1500 rds. The 7 prc/7mag 8T is The Perfect hunting round for <1000 yards, it carries just enough energy to 1000 yards, about 1200#'s. Without excessive recoil.
Imo for a cartridge to be a effective LR round it must be able to shoot a .6+ g1 bc bullet over 2900 fps. And for hunting it must have 1200#'s of energy at its max range, my desired max range is 1000 yards.
I would recommend a 7 prc, 28 Nosler or a 300 wsm, and over a 300 prc. 300 wsm resently set the world record 1000 yard 10 shot group. Most hunters wont shoot past 1000 yards on game, making the 300 wsm a better choice, less recoil.
Ballisticly the 300 prc and 28 nos are very close. The 300 prc's 30 cal heavier bullets slightly edge out the 28 nos on energy, with more recoil obviously.
If you're not reloading a 300 wm would have many many more choices of factory ammo. So you have a much better chance of finding a good shooting ammo. Reloading opens up more choices like a 7mag 8T, and the Sherman cartridges.
I would go 300 wsm or 7 prc.
But if your learning to shoot LR, a big mag cartridge is the wrong way to go. You should be learning on a 6mm, like a 6xc or 6cm. Then go to a hunting cartridge.
