270 and 30-06 carry enough power out to 700 yards, 7mm pulls a bit further, and 300 win mag pulls a bit further still. Meantime, lets enjoy our deeper dive into flat shooting hunting cartridges (hand carried and shoulder fired. 500-yard drop: 45 inches (based on a 100-yard zero). So what makes this round a real standout? Mag. plays a major roll in trajectory, but is second in significance to muzzle velocity. The 7mm Rem. Accordingly, the Weatherby .338-378 can launch any given projectiles weight out the muzzle faster than any other .33-caliber cartridge. Nosler Trophy Grade with a 150-grain Nosler AccuBond Long Range at 3300 fps. It gives you an MPBR of 336 yards. Take a look at the MPBR column and note how close they all are. | Weatherbys To be fair to the 30-378, itmurders everything else for flatness way out there, staying feet above most other cartridges and carrying enough energy to take a deer at just over 1000 yards. The .22 Winchester Magnum Rimfire, commonly known as the "Twenty-Two Win Mag," was hatched back in 1959. A 100-grain .243 bullet with a G1 ballistic coefficient around .400 at a muzzle velocity of 2,960 carries just over 800 foot-pounds of energy at 500 yards. Any cartridge that drops less than 40 inches at 500 yards or close to 200 inches at 1000 yards should be considered a flat shooting cartridge. A flat shooting cartridge matters. For good reason. With the highest BC bullets, the 26 Nosler remains supersonic beyond 1,750 yards. He just never made it official. While the .338-378 round will still be capable of supersonic velocity at 1,500 yards, it will have 831 foot-pounds of retained energy at the same distance. 2023 Outdoor Sportsman Group. gundata.org has done all this for you already. The new .300 Precision Rifle Cartridge (PRC) use as a parent case a .375 Ruger, which Hornady ballisticians necked-down to .30 caliber and moved back the shoulder to make a cartridge with very long head height. If you like the idea of a six-five for going long, but hate the Creed and want something a bit different, the 6.5-284 Norma is the way to go. Utilizing the heavier, slender and more aerodynamic bullets than the .223 Rem, the Valkyrie best performs outside 500 yards. Drops just 11.6 inches. As a numeric designation, the ballistic coefficient (BC) is usually described as a number between one and zero. A 100 yard miscalculation short or long will vary your hit by a vertical of 2.3-2.9 feet, enough to completely miss or wound the deer. And if you want an affordable hunting or target rifle the Creedmoor is a good option. This cartridge existed in a cloak of obscurity for a long time; only recently have hunters began to see the potential it offers. Hornadys 147-grain 6.5 Creedmoor Match load shoots flatter that their .308 168-grain Match load and carries more energy at long range. Most common calibers are just fine for regular range shots under 300 yards.

With the ability to handle more aerodynamic bullets than the .270 Winchester or the .270 WSM, the 6.8 Western and its 1-in-8 twist rate allows this cartridge to outperform both at distance. As you can see, one of our gold standard flat-shooting cartridges (.270 Winchester) does not compare favorably with either of the Noslers or the Weatherby Magnum. The Complete Guide to AR-15 Cartridges - Shooting Illustrated By the way, while the 6.5-300 has been on the market just five years, Roy was shooting it in the mid-20th century. Comparing the two of the same caliber but different shapes projectiles, one heavier and a long-for-caliber bullet with a boat tail at the end will have a better ballistic coefficient. In brief, the ballistic coefficient is a mathematical representation of how streamlined a bullet is, i.e., projectile's ability to resist air drag. As the old system for measuring BC, the G1 model is based on a short, flat-bottomed bullet, while the G7 model is based around longer, boat-tailed bullets. So, if you want to go long, there are some clear choices here. My take away on all this number crunching? It will push a 55-grain E-Tip bullet to 3,300 fps, which is more than sufficient for deer hunting. Like the 6.5 Creedmoor, the .280 Ackley Improved can remain supersonic out to 1,400 yards. 7.62x54 ammo might be cheaper . The reason why 6.5mm cartridges are exploding in popularity is because they are ultra-efficient. 264 Winmag However, the lead that the 25-06 has is pretty small. Ive included different bullet weights/BCs for most rounds to illustrate how BC changes drop at longer ranges. I also want to give credit to a couple of long-range AR cartridges that deserve honorable mention. Moreover, a manufacturer advertises at 400 yards their 6.5mm projectiles maintain the same velocity as the .260 Remington generates at the muzzle. 1.Humans are more important than Hardware. These different models rate the aerodynamic qualities of a bullet from which the drag and BC can be measured. Introduced by Remington in 1962 along with their Model 700 bolt-action rifle, Remingtons Seven-Mag was the beginning of the end of Winchesters .264. What Is The Flattest Shooting Rifle Caliber | RiflesInTheUK.com Generating muzzle energy of 400 ft-lbs, this innovative rimfire round easily outperforms all previous rimfire varmint cartridges and duplicate the centerfire velocities and energy in a more affordable rimfire package. The BC calculations are made in relation to the particular standard projectile shapes by measuring how efficiently they overcome air resistance in flight and how well retain velocity and energy as they travel downrange. projectile that you might crown that one King, especially since that 100-grain sounds a bit more reasonable for deer-sized game. We are not going to include here the esoteric military sniping rounds engineered for 1,000 yards, 2,000 yards, even 3,000 yards. With a muzzle velocity of 2,860 fps the .300 PRC 212-grain ELD-X load generates 3,850 foot-pounds of energy at the muzzle and carries over 2,200 foot-pounds of punch at 500 yards.
