That’s how the two cartridges compare to each other in a nutshell. 46 98 Do you have a rifle chambered in 300 PRC that you’re itching to take on a hunt? As you can see in the photo below, the 300 PRC can use long, sleek bullets without seating them so deep they intrude into the powder column or contacting the rifling upon chambering. 0000062570 00000 n So, they took a necked down .375 Ruger cartridge case and built the cartridge with a very long head height. I’ll also provide some information on how the 300 PRC stacks up next to the .300 Winchester Magnum so you can decide if it fits your needs as a hunter. I used Shooters Calculator to compare trajectories, wind drift, and recoil for the cartridges. While the .300 Win Mag is certainly capable of excellent accuracy in the right hands, the 300 PRC was specifically designed for exceptional accuracy and outstanding performance at long range. Unfortunately, the 300 PRC does have more recoil than the .300 Win Mag though.
This meant a maximum overall length of 3.34″. 0000115340 00000 n Ultimate Reloader LLC is not responsible for errors in load data on this website. Loaded with a high BC 212 grain ELD-X bullet, 300 PRC Precision Hunter ammunition has a flatter trajectory and carries more energy down range than otherwise identical .300 Winchester Magnum ammo. 0000053332 00000 n So, the 300 PRC does have an advantage in this area, but once again, there’s not a gigantic difference between them. Always cross-reference load data with manufacturer's published data.
I chose this press because of the long cartridge length for 300 PRC (3.700″ max COL, and I will go beyond that in testing!). 0000052967 00000 n Maximum pressure for the .300 Win Mag and maximum pressure and cartridge dimensions for the 300 PRC were obtained from SAAMI (p172 for the .300 Win Mag) and here for the 300 PRC.

So, if you’re the type of person who wants to wring out all the performance you can from a certain caliber, by all means get a 300 PRC. Since it’s used by a relatively small segment of the hunting world, not every sporting goods store keeps 300 PRC ammo in stock, but most of the big retailers in the USA usually have a couple of boxes of ammo on hand for the cartridge. Otherwise, i think you’re unnecessarily handicapping yourself and I’m not sure how much of an advantage the 300 PRC will provide you over your 300 Win Mag.

So when I’m loading match ammo, there’s no downtime for charging and seating- a smooth operation! Poll: What Progressive Reloading Press Do You Use Most? As you can see, the two cartridges have virtually the same muzzle velocity, but the 300 PRC shoots a heavier and more aerodynamic bullet. 300 PRC and .300 Win Mag factory loads generally have similar muzzle velocities, but the 300 PRC shoots a heavier bullet with a higher BC. Since gun manufacturers build their rifles to those same specifications, there simply isn’t enough space in a standard length rifle action (or magazine) for those longer bullets. 0000116789 00000 n This data is for Hornady Precision Hunter factory ammo using a 200 yard zero and a 24 inch barrel. 0000002947 00000 n The flatter trajectory and more resistance to wind drift of the 300 Precision Rifle Cartridge can also help with shot placement. The chart below compares how much a 10 mile per hour crosswind impacts those same loads for each cartridge out to 500 yards.
dai meter: 0.308" * 212 e. lgdrx-®item no. But it can be difficult to prime these cases with “light duty” priming tools. Note: while the powder capacity figures listed above do give a good indication of the differences between the two cartridges, exact case capacities vary slightly according to the brand of brass used. 0000075238 00000 n 0000061550 00000 n This is reflected in the prices, availability, and variety of factory ammunition and hunting rifles currently in production for each cartridge. 0000041850 00000 n Material connection (partnerships) information available at http://ultimatereloader.com/about/, Don’t miss out on Ultimate Reloader updates, make. 0000030693 00000 n With careful handloading, it’s possible achieve slightly higher velocities with the cartridge and/or utilize even heavier and more aerodynamic bullets. ]�Π�Й����2��]����z�V�4�S�ϐO3]�t5�5LWsG�;�d�d�d�d�d�d�d�d�d�d�d�d�tmc��l�t��B�]�/S�y���������ǈ�y������3� In fact, that is one of the other selling points of the 300 Precision Rifle Cartridge: it delivers a definite advantage over other .30 caliber cartridges at long range, but without the punishing recoil of higher tier long range cartridges like the .338 Norma or .338 Lapua.

There is some overlap in the common bullet weights they use, but the 300 PRC generally works better with longer and heavier bullets. 0000083379 00000 n trailer <<6F5D165DDAB54D558E0C5F20116A3083>]/Prev 190249>> startxref 0 %%EOF 143 0 obj <>stream The Big Game Hunting Blog is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, Amazon.ca and other Amazon stores worldwide. As previously stated, both cartridges have the same .532″ case head diameter. One thing I’ve noticed about Hornady rifle cases is how tight the primer pockets can be. This results in increased case capacity for the 300 PRC (and the 375 Ruger) cartridge while still working with a standard magnum bolt face. Unlike the .300 Win Mag, there aren’t many options for factory 300 PRC hunting ammo right now.

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. 300 PRC is a precision long-range cartridge and shooting platform. 0000116594 00000 n
The high price of factory ammo and the difficulty involved with obtaining a reliable supply of ammo at times makes it a good choice for handloaders. That translates into a slightly flatter trajectory, a little more resistance to wind drift, and a little more kinetic energy at typical hunting ranges. Testing Hornady 225ELD match, 200 grain Sierras, 215 Berger, 230 A tips. Basically, having more head height means the 300 PRC offers more room outside the case for bullets than the .300 Win Mag.
