Will someone do a Quick Load check for me on the following:
.223 Rem. LC 1.75" case CCI 450 IMR 4895, 24.8grs Nosler Varmageddon 55gr Flat Base Hollow Point BC: .218 Sectional Density: .157 14.5" barrel I'm looking for velocity at muzzle, 50yds, 100yds, and 200yds. Might be going on a coyote cleansing, need to know if this load will have enough zip out to 200 yds. Thanks, John |
