Both the 6.5 Creedmoor and .260 Remington can shoot a gamut of .264 bullets, but once a VLD bullet get much heavier than 142 grains, the slower twist rate of many .260 Rem. Both these bullets have the same 6.5 mm diameter in the round, which typically accommodate with the .308 Winchester rifles.The firearm community believes in the quality of both of these bullets. When Remington in 1997 legitimized the wildcat 6.5-308 (.308 Winchester necked down to hold a .264 bullet) competition shooters had been succeeding with it for many years, pushing the best 140-grain competition bullets of the day. The 6mm Creedmoor uses a 30 degree shoulder angle, its max case length is 1.92" and the COL is 2.8" The SAAMI MAP is 62,000 psi. Hunters were fairly quick to recognize the accuracy benefits of this spin, but militaries were less eager to exchange their fast-loading smooth bores for the slower, tighter fit of bullets rammed into rifled barrels. The.260 Remington and 6.5 Creedmoor are very similar rounds. With this in mind, rifling twist was set at 1:8″. Federal has a 142-grain Sierra MatchKing Boat-Tail Hollow Point, B.C. Mag. This cartridge is new to the shooting world, but it has been winning target competitions and bringing down animals at a high rate since its inception.The 6mm Creedmoor is nearly identical to the 6.5 CM which we have reviewed and compared to the .243 Win in a previous article. Remington’s parent case is actually .308 Winchester and its closely related .260 Remington is also based on a 308 cartridge. That wasn’t exactly playing to its strengths. Interestingly, twist rates were never standardized. Necking down of the 6.5 CM allowed the base to be fitted with a .243 cal bullet and allo… This is why bird shot scatters ever farther as it progresses downrange. By the 1930s, folks had pretty much figured out that .257 to .338 bullets launched at 2,300 fps or faster were effective for most big game hunting. rifles makes stabilization problematic. But, that advantage won’t show itself until well past sane hunting ranges. If one is looking for velocity, the 6-284 has more capacity, and will yield a bit more velocity. did not. Factory ammunition was tailored for the best long range precision, too. Many high velocity varmint cartridges were set up with 1:12 to 1:14 twist rates to balance 40- to 55-grain .224 bullets. The rifle will be off to the gunsmith again shortly and it'll be 260AI this time. Never mind that thousands of hunters regularly bring home the venison with .243 bullets as light as 70-grains. Ammo makers loaded bullets that stabilized in all these, so .260 Rem. and 7mm-08 Rem. Load either case with a decent hunting bullet—one that will hold together at close distances, yet expand at lower velocities—and you’ve got a setup that will put meat in your freezer for a lifetime. My Rifle Kit. Over the past decade the 6.5 Creedmoor has become among the most popular long range shooting cartridges available.

(Ron Spomer/) Meanwhile, there sat the .260 Rem. By the way, many bullets spin at the rate of 300,000 rpms. Weights were balanced to bores and the game expected to be hunted with such bore sizes. Hornady has ammo with 129-grain SST bullets rated .485 B.C. and in the same general category as the 6mm Lapua, .243 Winchester and 6mm Remington. values and downrange performance—to be seated properly, whereas the .260 Remington case would require the bullet seated so deep in the case that the case mouth would be aligned with the ogive, and not the shank of the bullet. Overall, the Remington Model 700 Magpul Enhanced is a feature-packed rifle whose stock seeks to wring out every little bit of the barrel’s accuracy potential without dinging the wallet too harshly. The reason for this is that seasoned hunters have expertise in reloading. If you’re not intending to hire it to win any PRC competitions, you could find yourself with a delightfully efficient and effective deer/pronghorn/sheep and even elk rifle capable of performing as well as or slightly better than the .270 Winchester to 300, 400, even 600 yards. Regardless the fine points, the practical matter for hunters is that twist rates are more often too slow than too fast. The 6mm Creedmoor Remington 700 was able to reach out 800 to 1,100 yards with ease and given my level of expertise is just as capable as the custom built precision rifles. They chambered it accordingly with the rather low B.C. 6.5 CM is 200 FPS slower when matching powder to powder. Anything chambered .260 Rem. The ability to pinpoint target distance suddenly made long range shooting more than a guessing game. Berger offers three loads with sleek bullets from 120- to 140-grains, the latter boasting a G1 B.C. While the .260 Remington and 6.5 Creedmoor use similar amounts of powder (with the .260 Rem sometimes using a tiny bit more than the Creedmoor), many 6.5 Swede loads (especially in North America) use somewhat less powder.

Hornady gave it to them with its “ground up” 6.5 Creedmoor, the first 6.5 round specifically engineered to optimize long range shooting success with relatively long, high B.C. Recently, the 6mm Creedmoor cartridge which propels lighter thinner 6mm/.243 caliber bullets at higher velocities is becoming an attractive alternative. The 6.5x55 Swede has been making meat since the late 19th century and continues to do so each season, with no end in sight, and while it is extremely popular in Europe, the following here in the States is fervent, if small.

Most 30-calibers from .30/30 through the magnums twist 1:10, but a few rifle brands have produced 1:12. The recoil energy and recoil velocity figures are taken from various sources including the recoil nomograph in the Handloader's Digest 8th Edition, various online recoil calculators, the Remington Shoot! That’s usually enough to stabilize 175-grain spire points and even some 180-grain. and 6.5-284. While the .260 Rem and similar cartridges like the 6.5-284 Norma, 6.5x47 Lapua, 6.5 Grendel and Hornady’s new 6.5 Creedmore have come to dominate long-range competitive shooting, with hunters it’s been a different story. Meanwhile, there sat the .260 Rem. After a brief fling with uber-magnums like the .50 BMG and .338 Lapua Magnum, recreational long rangers started looking for similar reach with dissimilar recoil. bullets and still maintain the maximum overall length suitable for use in a short-action magazine. Englishman Alfred Greenhill developed a mathematical formula for determining twist rates for lead bullets in 1879 and it still works pretty well today, although variations like bullet material, hollow points, etc., alter things a bit. From left to right: 6.5 PRC, 6.5 Creedmoor, .260 Remington, 6.5-284 Norma, 6.5 Remington Magnum, .264 Winchester Magnum A partial solution does exist. Rifles were sculpted to maximize long-range precision. @2019 - The Sports National. 260 Remington and 6.5 Creedmoor are two common cartridges used for rifles.. With a 140-grain bullet, the Creedmoor gives a muzzle velocity of 2710 fps or so, depending on barrel length, so it’s right on par with the .260 Remington regarding trajectory, when comparing the same bullet weight. The original 6mm Rems are somewhat rare, but the 6mm Creedmoor seems to have a lot going for it, including a surprisingly accurate Ruger predator. The upshot was that during the 20th century, manufacturers established rifling twist rates by cartridge based on typical bullets then in vogue. The 260 Rem. Manufacturers could have kept the .260 Rem. In the hunting fields, a competent rifleman will be able to take either cartridge and get the job done. The advent of elongated bullets in the first half of the 19th century changed rifling significantly because the long bullets required more spin to stabilize. ... .260 Rem is a necked down .308 Win and is harder to find ammo for Get the .243 Win and WIN ... get the 6mm cm since you got 6.5.
