However, just to give you an idea of the benefits of the 300 PRC over the .300 Win Mag at long range, consider this: the .300 Win Mag has 20″ (~8%) more bullet drop at 1,000 yards and 96″ (12%) more bullet drop at 1,500 yards with a 200 yard zero. One will be 1:9.5 twist (the custom 300 PRC used in this article), and the other will be 1:8.5 twist, as a part of … However, unlike the .375 H&H (and cartridges like the 7mm Rem Mag and .300 Win Mag descended from it) the .375 Ruger is a beltless cartridge, so the actual body of the .375 Ruger case is larger in diameter than the .375 H&H. This data is for Hornady Precision Hunter factory ammo using a 200 yard zero and a 24 inch barrel. Whichever group gives the best results is the optimal charge weight for your rifle. If you really enjoy shooting at longer range, then the inherent accuracy of the cartridge and the fact that it’s designed to use very heavy, high BC bullets are both compelling arguments in favor of the 300 PRC. Let’s get to it! That’s like hitting two birds with one stone! I’ll cover that next! If you would like to develop loads for multiple projectiles, you will need to purchase multiple load packs. Of the two cartridges though, the .300 Win Mag is still by far the most popular with hunters. In fact, the .300 Winchester Magnum is probably the better all around choice for most hunters. However, the actual body diameter of the 300 PRC is the same diameter as the belt on the .300 Win Mag. Hence starting on the low side and working up to the calculated/interpolated max charge. Buy a nice 300 Precision Rifle Cartridge hunting rifle here. Existing cartridges like the .300 Win Mag were certainly capable of excellent long range performance, but there wasn’t a .30 caliber cartridge purpose built for that task.

So clearly we will be running the -.010” load with the lower ES even though the -.015” load shot slightly tighter.

That translates into a slightly flatter trajectory, a little more resistance to wind drift, and a little more kinetic energy at typical hunting ranges.
