I've wanted to buy a 7mm more potent than my 7x64. And the 7mm PRC has caught my attention. I'm not a long-range hunter. But efficient cartridges with high BC bullets will give me more room for error in open country. That's at least what I think. Am I right or wrong?
To find out, I'll compare the 7mm PRC against other 7mm cartridges. And I'll compare it based on Killing Power Scores, wind go/no-go charts, and Weapon Employment Zone analysis.
The candiaates are: 7mm-08, 280 Rem, 280 AI, 7mm WSM (Winchester Short Magnum), 7mm PRC, 7mm Rem Mag, 7mm STW (Shooting Time Westerner) and 28 Nosler.
And I'm basing the test on Hornady Precision Hunter Ammunition loaded with ELD-X bullets.
I am not affiliated with Applied Ballistics and have purchased the AB analytics package I use. I do, however recommend this software to anyone hunting in open country. Not just long-range hunters.
