New for 2018 - introduced for the general public in mid-2018, the
22 Creedmoor was a wildcat caliber, produced by necking down
the *6.5mm Creedmoor to accept the smaller .22 cal. projectile.
From what I have read, the .22 Creedmoor was a wildcat designed
by GAP (Georgia Precision) specifically to shoot long, heavy .22
caliber bullets at high velocity while providing a good barrel life
and flawless feeding from detachable mags.
*The 6.5 Creedmoor was introduced in 2007 by Hornady, based on
the .308 case; In other words, the .22 Creedmoor is very close to a
22/.243 Winchester wildcat, with a little better case design and
Ballistics: a 90 grain projectile in .22" diameter is app. 3,300 feet
per second muzzle velocity using a barrel with a recommended
twist of 1to7 ″, producing app. 2,100 foot pounds of energy.
