Videos tagged with Keyholing

This video investigates an accuracy problem with a Browning XBolt 2 in 6.5 PRC, identifying a 1:7 twist rate as a potential cause for keyholing and poor performance with certain ammunition. The investigation involved testing the twist rate, examining the barrel, and consulting with ammunition manufacturers. The conclusion suggests a combination of an overly fast twist rate and ammunition construction issues led to the observed problems.

This video addresses several user-submitted questions regarding firearms. Key topics include the Zerus Arms Waltz 9's ammunition preference (hotter is better), common issues like erratic ejection and failures to return to battery on 2011 platforms, and advice on managing 'Glock knuckle' and improving shooting while moving. The discussion also touches on keyholing with specific ammunition and firearm combinations.

This review of the Browning XBolt 2 highlights its popularity among hunters but reveals significant accuracy issues with several ammunition types. While the rifle's feeding mechanism and build quality are praised, the inconsistent performance, particularly the keyholing observed with Remington ammunition and the potentially problematic 1:7 twist rate for 6.5 PRC, raises concerns. The Athlon Aries HLR 4-20x50 scope is noted for its excellent turrets and clear glass, though it's a second focal plane model.

This evaluation of the Rare Breed FRT-15L3 by Regular Guy Training LLC details a rigorous 6,000+ round test over one month. The assessment highlights the importance of monitoring barrel wear, evidenced by keyholing, and the process of replacing a worn barrel to continue testing. The speaker, a professional firearms instructor, demonstrates high-volume round count testing to provide an experience-based evaluation.

This video demonstrates the dangerous consequences of firing incorrect ammunition in a .308 Winchester rifle. The host, exhibiting high-level expertise, tests .243 Winchester, .260 Remington, and 7mm-08 Remington rounds, highlighting issues like fire-forming brass, extreme inaccuracy, tumbling projectiles, and significantly reduced velocity due to gas blow-by. While technically possible in a dire emergency, the experiment concludes that using the wrong caliber is ineffective and hazardous.

This entry details the extreme wear on a Glock 26 barrel after 121,600 rounds, leading to a completely smooth bore and 'keyholing' projectiles. The content highlights the seller's unique approach to testing firearm part longevity and the visual evidence of extreme rifling depletion. It serves as a case study in the limits of firearm component durability.

This review from GUNBROS details the Daniel Defense H9 as the most disappointing firearm release of 2024. The speaker, exhibiting high authority as an industry professional, highlights widespread reliability issues, including 'keyholing,' that plagued the initial release. Despite Daniel Defense's efforts to address these problems through barrel replacements and repairs, the negative sentiment and lost market hype present a significant challenge for the manufacturer.

This review of the North American Arms Switch Gun, presented by a firearms reviewer, details its operation and loading procedure. The video highlights the firearm's compact, folding design and demonstrates its manual of arms, including cylinder removal for loading. Accuracy testing revealed significant issues with bullet stabilization, leading to keyholing on the target.

This video from Classic Firearms explains the critical relationship between rifle twist rates and ammunition bullet weight for optimal ballistic stabilization and accuracy. The hosts, Matt and Jason, detail how different twist rates (e.g., 1:7, 1:8, 1:9) are designed to stabilize specific bullet weights and lengths. They emphasize that using the wrong ammunition can lead to under or over-stabilization, resulting in poor accuracy, keyholing, or yawing. The discussion covers common calibers like 5.56 NATO and 300 Blackout, providing guidance on selecting appropriate bullet weights for various twist rates to maximize rifle performance.

This follow-up video tests the impact of bore condition on accuracy at 15 yards using a P38 pistol with interchangeable barrels. The experiment compares a pristine barrel to one with significant wear. While close-range differences were minimal in a previous test, this extended distance aims to reveal if bore quality significantly affects bullet stability and terminal impact.

This video from SPN Firearms details an inspection of a Glock 26 barrel with an astonishing 121,600 rounds fired through it. The speaker, an experienced firearm enthusiast, highlights the extreme wear on the barrel, comparing it to a new one and explaining the phenomenon of 'keyholing' caused by rifling degradation. The content serves as a testament to Glock's legendary durability while also demonstrating the practical limits of firearm components under high-volume use.
