This guide details a deep cleaning process for bolt-action rifles experiencing accuracy degradation, inspired by Ron Spomer's insights. It covers identifying the problem, understanding the theory behind cleaning for different bullet types, performing a baseline test, executing a thorough cleaning with specific tools like a borescope, and re-testing for improved accuracy. The process emphasizes removing all fouling to restore sub-MOA performance.

This video provides a first look at the Sightmark Presidio scope, highlighting its durability and performance features. The reviewer, Jim Harmer, demonstrates its waterproof capabilities by submerging it and confirms its turret tracking accuracy for long-range shooting. The scope is presented as a budget-friendly option with features typically found in more expensive optics, including an illuminated reticle and a throw lever for quick magnification adjustments.

This video provides an in-depth analysis of ammunition manufacturer claims regarding muzzle velocity and ballistic coefficients. The host, demonstrating high expertise through rigorous testing and data citation, reveals discrepancies between advertised and actual performance for several popular calibers and bullet types. Key takeaways include the importance of real-world velocity data for ballistic calculations and comparisons between calibers like the 6.8 Western and 7mm PRC.
