This New Barrel Made Factory Ammo 36% More Accurate | Proof PXT vs Proof Traditional

Can a barrel really make your rifle 20–50% more accurate without changing ammo, optics, action, or shooter? That's exactly what we're testing today! I put the brand-new Proof Research PXT (Proof Exponential Twist) barrel head-to-head against a traditional Proof carbon-fiber barrel using the same rifle platform, same shooter, and eight different factory 6.5 Creedmoor loads ranging from 120gr to 156gr bullets. No handloads. No cherry-picked groups. Just real-world shooting and data. We tested: Hornady 140 ELD-M Hornady 120 ELD-M Winchester 129 Power Point S&B 156 Grain Remington Core-Lokt 140 Norma Whitetail 140 Federal Fusion 140 Hornady Precision Hunter 143 ELD-X Along the way we tracked: Group size, Velocity, Extreme Spread (ES), Standard Deviation (SD) The results honestly surprised me! The PXT consistently produced tighter groups. If you're a hunter, precision rifle shooter, handloader, or just someone wondering whether the latest barrel technology is hype or reality, this test is worth watching. 00:00 The Accuracy Claim Sounds Impossible 00:48 What Is Proof's New PXT Barrel Technology? 02:49 Test Rifle Setup & Equipment Overview 06:18 Accuracy Test Begins: Hornady 140 ELD-M 09:16 Hornady 120 ELD-M Results 11:50 Winchester 129gr Power Point 14:10 S&B 156 Grain Testing 16:34 Remington Core-Lokt Performance 19:39 Norma Whitetail Results 22:27 Federal Fusion 140 Results 24:35 Hornady Precision Hunter 143 ELD-X Results 27:41 Final Data Breakdown & Accuracy Comparison 34:18 What About Long Range, Barrel Life & Semi-Autos? 36:13 Final Thoughts on the PXT
