TN-24 — Drop & Drift Table (100–1,200 yd) Normalized, source-replicable ballistic tables for representative 6.5 Creedmoor loads.
This Technical Note provides a normalized drop and wind-drift reference table for typical 6.5 Creedmoor match loads. All values are derived strictly from publicly available ballistic data, chronograph ranges, and SAAMI specifications — no proprietary or unpublished data is used. This TN is a cross-reference anchor for multiple chapters in the 6.5 Creedmoor Cartridge & Rifle Compendiums.
I. Purpose of This Technical Note 6.5 Creedmoor’s ballistic appeal is rooted in predictable, repeatable flight behavior. For that reason, shooters benefit from a standardized reference table that: Normalizes drop and drift across 100–1,200 yd, Uses representative BC values (e.g., modern 130–147gr match bullets), Uses realistic chronograph velocities (2,650–2,780 fps windows), Provides a consistent baseline for chapters on external ballistics, wind, optics, and zeroing. This TN is intentionally load-agnostic. It is a framework — not a prescription.
II. Representative Load Parameters These are “reference loads,” constructed from aggregated public ballistic data: Load A (Common Match Profile) Bullet: 140gr class (ELD-M / BTHP / OTM equivalents) G1 BC: 0.60 (normalized) Muzzle Velocity: 2,700 fps (24″ baseline) Zero: 100 yd Atmospherics: Standard (59°F, 29.92 inHg) Load B (Modern High-BC Variant) Bullet: 147gr class G1 BC: 0.70 (normalized) Muzzle Velocity: 2,650 fps Zero: 100 yd Both represent publicly documented ballistic envelopes.
