This guide details a method for creating a custom bullet seating stem for .223 Remington 75gr Hornady BTHP bullets, addressing issues with inconsistent seating and bullet marking. The process involves using JB KwikWeld epoxy to form a precise mold of the bullet's ogive within a standard seating stem. This technique, demonstrated by a high-level reloading expert, ensures better bullet alignment and more consistent overall length (OAL) in reloaded ammunition.

This video details a comprehensive reloading experiment testing 19 different powders with the 75gr Hornady BTHP bullet in .223 Remington. The instructor aims to find a cost-effective path to replicating Mark 262 clone performance, analyzing group sizes and velocities for each powder charge. Several powders, including Hodgdon H322, Vitavouri N135, and AR Comp, showed promising accuracy, with AR Comp emerging as a potential top contender for further development.

This video details the process of reloading .223 Remington ammunition using 75gr Hornady BTHP bullets with Varget N540 and Alliant Power Pro Varmint powders. The instructor demonstrates seating bullets to a specific overall length, discusses charge weights, and presents ballistic data from test firing at 100 yards. The analysis includes group sizes, velocities, and brass inspection for pressure signs, offering insights into powder and bullet combinations.

This video details the break-in and accuracy testing of an 18-inch White Oak Armament SPR barrel in .223 Wylde. The test highlights the barrel's exceptional accuracy with various bullet weights and powders, particularly the 75gr Hornady BTHP and 69gr Sierra MatchKing. It also covers essential components like the adjustable gas block, suppressor, and optics, providing valuable insights for AR-15 builders seeking precision.
