6.5 Creedmoor - 140gr Nosler RDF with H4350
This video details a systematic approach to optimizing accuracy for the 140gr Nosler RDF bullet in 6.5 Creedmoor, emphasizing the critical role of overall cartridge length (COL) testing. The instructor, despite past accuracy issues with Nosler bullets, demonstrates a method inspired by Berger's recommendations, testing multiple COLs in 0.040-inch increments to find the rifle's sweet spot. The process involves careful bullet seating, precise measurement to the ogive, and shooting groups at 100 yards to evaluate performance.
