7mm PRC vs 7mm Rem Mag vs 280: Not Even Close?

This comparison tested the penetration capabilities of 7mm Rem Mag, 300 Win Mag, and 338 Win Mag against various barriers including wood, mild steel, sand, and concrete. While all calibers performed similarly through wood, sand, and concrete, the 300 Win Mag demonstrated superior penetration through thicker mild steel plates, making it the overall winner in this specific test scenario.

This Dangerous Liberty Podcast episode, number 7, focuses on a comparative ballistic analysis of four popular rifle cartridges: 6.5 Creedmoor (6.5 CM), 6.5 PRC, 7mm PRC, and 300 PRC. The discussion aims to help viewers understand the pros and cons of each caliber and determine which might be the best choice for their specific needs. The episode was scheduled to air live at 7 pm EST.

This video provides an in-depth review of the world's first public 7mm PRC rifle build. It details the custom rifle's specifications, including the Defiance action, Preferred Barrel Blanks barrel, MDT chassis, and Leupold optic. The review includes crucial velocity testing with various powders and bullet weights, offering valuable insights into safe pressure limits and expected factory load performance. A direct comparison with the 7mm Rem Mag highlights the 7mm PRC's velocity advantage.

The 7mm PRC cartridge has officially been released and SAAMI certified, with Hornady expected to make a public announcement soon. It offers superior energy and effective range compared to common hunting cartridges, boasting a maximum effective range of 910 yards and a 4-inch MPBR out to 265 yards. Designed for efficiency, it aims for a balance between performance and barrel life, estimated at 1,500 rounds, with manageable recoil.

The 7mm Rem Mag offers a slight velocity advantage (approx. 70 fps) over the 280 AI, but with diminishing returns in terms of powder usage and recoil. The 280 AI is more efficient, allowing for shorter barrels and better magazine capacity. While the 7mm Rem Mag boasts superior rifle and ammunition availability, the 280 AI can safely fire standard .280 Remington rounds.

This video features a custom 7mm PRC hunting rifle build, showcasing a Terminus action Zeus, Maven optic, Grayboe stock, MDT Ckyepod, and Triggertech trigger. The core of the video focuses on a ballistic test comparing factory Hornady 175g ELDX hunting ammunition against handloads using H1000 and Ramshot LRT powders. The content includes range testing with group shots and long-range engagements, followed by the presenter's thoughts on the handload performance. A previous video (Part One) is linked for context.

This comparison tests the .50 AE Desert Eagle against the .44 Magnum in various barrier tests, including wood, steel, sand, and concrete. While both calibers showed impressive power, the .50 AE demonstrated superior performance in ballistic gel with deeper penetration and a larger wound channel. Ultimately, the video questions if the .50 AE's marginal gains justify its significantly higher cost per round compared to the versatile .44 Magnum.

This video provides a detailed comparison between .223 Remington and 5.56 NATO ammunition, demonstrating their performance differences through rigorous barrier testing. While visually identical, 5.56 NATO shows a slight advantage in velocity and energy. Crucially, 5.56 NATO exhibits superior barrier penetration against lumber and steel, whereas .223 Remington struggles. Specialized rounds like M855A1 also show enhanced performance against sand barriers.

This video tests the lethality of various 'less lethal' shotgun rounds, including rubber buckshot, bean bags, and specialized projectiles. The .410 rubber buckshot demonstrated significantly higher velocity and penetration than 12-gauge versions. Bean bag rounds proved to be the most damaging, causing substantial plywood destruction and ballistic gel displacement, leading the host to conclude they are the most lethal 'less lethal' option.

This video compares 9mm, .40 S&W, and .45 ACP through various barrier tests including lumber, sand, and concrete, alongside ballistics gel testing. While all calibers performed similarly through most barriers, the .40 S&W showed slightly better penetration and expansion in ballistics gel. The host ultimately favors 9mm due to its lower recoil and higher capacity, despite the .40 S&W's respectable performance.
