ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy (E t) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f) for non-SI units of measure.
The .375 Ruger cartridge has also functioned as the parent case for the 6.5 Precision Rifle Cartridge (6.5 PRC) [17] and 7mm Precision Rifle Cartridge (7mm PRC), [18] which are essentially necked-down shortened versions of the .375 Ruger. American ammunition manufacturer Hornady got the 6.5 PRC SAAMI-standardized in 2018 simultaneously with the ...
The RPR was originally announced in the following calibers and configurations: .308 Win. with 1:10 twist, 20 in (51 cm) barrel, weighing 9.7 lb (4.4 kg) 6.5 Creedmoor with a 1:8 twist, 24 in (61 cm) barrel, weighing 10.6 lb (4.8 kg)
The 6.5mm Creedmoor designated as 6.5 Creedmoor by SAAMI, and as 6,5 Creedmoor by the C.I.P. [ 4 ] is a centerfire rifle cartridge introduced by Hornady in 2007. [ 6 ] It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name.
Depending on their case material and bullet weight, 6.5mm Grendel cartridges weigh 14.7 to 17.8 grams (227 to 275 gr). The case head diameter of the Grendel is the same as that of the 5.6×39mm (.220 Russian), 7.62×39mm and 6.5mm PPC cases. This diameter is larger than the 5.56×45mm NATO, thereby necessitating the use of a non-standard AR-15 bolt
It lacks the power of the bigger .25-06 Remington but provides less noise and less recoil. Performance is very close to the .257 Roberts . Arguably it is a better overall cartridge for hunting than the more popular .30-30 , but in recent years has lost ground to the .257 Roberts and flatter-shooting 6mm cartridges such as the .243 Winchester .
Cartridges firing 6 mm or 6.5 mm (0.24 to 0.26 inch caliber) bullets are popular because low recoil often enables shooters to observe whether they have hit or missed a target to assess whether another shot is required before moving on to the next target. [2] Many competitors also use shooting bags to create a stable platform to rest their rifles.
