I’m not sure if this is an Ultimate Ammunition product, a Cadex product, or a co-branded venture, but I am sure it’s pretty darn cool. For those who take their extreme long range (ELR) shooting extremely seriously, precise muzzle velocities matter a whole heck of a lot.
Gunpowder and primers are temperature-sensitive, with changes in temperature causing small changes in burn rate. A 40-degree cartridge won’t fire the bullet at the same speed as a 108-degree cartridge will.
