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; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
In 1925, Winchester introduced the .270 Winchester, previously known as the .270 WCF, based on the 30-03 Springfield case necked down to .277" (6.8 mm). Although the .270 Winchester was not an instant success, within a few decades it became one of the most popular big game hunting cartridges for mid sized game worldwide, because of its relatively mild recoil and flat trajectory within ...
In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
These bullets include most Barnes' bullets over 110 gr (7.1 g) and any conventional spitzer bullet of over 115 gr (7.5 g). Hornady's 117 gr (7.6 g) round nose bullet is made for such firearms which have the slower spin rate. Norma loads this bullet in the Weatherby's H257117RN ammunition for owner of such rifles who require a heavier bullet.
Due to the necessity of seating heavier longer bullets more deeply into the powder column due to the short design and maximum overall length of the .325 WSM cartridge, velocity drops off as bullet weight increases. This is particularly evident with mono-metal bullets such as Nosler's E-Tip bullets, and the Barnes X bullets.
A full power load with fast powder can push a 165-grain (10.7 g) Barnes bullet to a muzzle velocity of 2,520 ft/s (770 m/s). Another favourite pick for such an exercise would be the 180-grain (12 g) Nosler Accubond or the 200-grain (13 g) Nosler Ballistic tip traveling at 2,200–2,350 ft/s (670–720 m/s).
Monolithic bullets have been used for hunting big game in the USA for decades. The first popular all-copper bullet was the Barnes X bullet in 1986. [7] Since then, most bullet companies have a monolithic bullet on the market, including Nosler E-tips, Hornady GMX, Barnes TTSX, LRX, VOR-TX, Federal Trophy Copper, Winchester Powercore 95/5, Hammer bullets, Cutting Edge Bullets, Lehigh Defense, G9 ...
