28 nosler vs 30 nosler vs 33 nosler

It features a lead-free 62 grain (4.0 g) projectile with a solid copper core, and is tailored for use in rifles with shorter barrels such as the M4 carbine. My 28" was 2950. Looking for some of the differences between .300 Win Mag and .30-06? and SAAMI ammunition rulings and recommendations. Easier to run the bolt, smaller rifle, and smaller ammo to carry! Eugene Stoner of Armalite (a division of Fairchild Industries) had been advised to produce a scaled-down version of the 7.62mm AR-10 design. 10. [53][54], The U.S. Marines adopted the Mk318 in early 2010 due to delays with the M855A1. The US Army Picatinny Arsenal stated that the new M855A1 offers improved hard target capability, more consistent performance at all distances, enhanced dependability, improved accuracy, reduced muzzle flash, and higher velocity compared to the SS109/M855 round. The lead slug is replaced by a copper alloy slug in a reverse-drawn jacket, with a hardened steel penetrator extending beyond the jacket, reducing lead contamination to the environment. The steel-tip penetrator of the M855A1 is noticeably separated from the jacket of the bullet and can spin, but this is part of the design and does not affect performance. The EPR can penetrate a 3⁄8 in (9.5 mm) thick mild steel barrier from an M4 at 350 m (380 yd) and from an M16 at 400 m (440 yd). 1; 2; First Prev 2 of 2 Go to page. Early development work began in 1957. [72][73] Some commercial rifles marked as ".223 Remington" are in fact suited for 5.56×45mm NATO, such as many commercial AR-15 variants and the Ruger Mini-14 (marked ".223 cal", except the Mini-14 "Target" model, which only fires .223), but the manufacturer should always be consulted to verify that this is acceptable before attempting it, and signs of excessive pressure (such as flattening or gas staining of the primers) should be looked for in the initial testing with 5.56×45mm NATO ammunition. Over 1 billion cartridges had been produced as of 2005[update]. [113] While effectiveness at different ranges is increased, the M855A1 does not increase the effective ranges at which weapons are expected to hit their targets. This failure of 5.56×45mm NATO bullets to yaw can be caused by reduced impact velocities as when fired from short-barreled weapons or when the range to the target increases. Experiments with longer length barrels up to 610 mm (24.0 in) resulted in no improvement or a decrease in muzzle velocities for the SS109/M855 cartridge. Previous experience of a change in standard rifle had proved that changing the distance of fire for the training ranges was more expensive than the design of a new ammunition; this prompted the design of a cartridge nominally capable at 300 meters. Custom Competition bullet at 2,950 fps. However, at impact velocities above roughly 762 m/s (2,500 ft/s), it may yaw and then fragment at the cannelure (the crimping groove around the cylinder of the bullet). The 7.62 NATO has twice the impact energy of the 5.56 NATO, preferable if a target is protected by higher level armor, especially at "medium" range. American Rifle: A Biography, Alexander Rose (2009) p. 375-376. They were originally bought 2-3 years ago for a Rem 700 LR because he didn't know any better. The Enhanced Performance Round was made to nearly match the trajectory of the M855 to aid in training consistency—the SS109/M855 ballistic coefficient (G7 BC) of 0.151 was improved to 0.152 for the M855A1[114]—but the ranges to get desired effects are greatly extended. [59], The exterior dimensions of the 5.56mm NATO and .223 Remington cartridges are identical. I have it’s predecessor (and ballistic twin) which is the 7 STW. [5], In September 1963, the .223 Remington cartridge was officially accepted and named "Cartridge, 5.56mm ball, M193." [79] The ArmaLite AR-15, officially designated Rifle, caliber 5.56 mm, M16, was later adopted by U.S. infantry forces as the standard issue rifle.[10][5]. The bullet uses an open-tip design to inflict damage on soft tissue, and has a brass rear to penetrate hard targets. At 300 yards 300 WM 2526 Ft energy @2447PFS with 190 Gr Accubond.30 Nosler 3193 FT Energy @ 2617 FPS with 210GR Accubond 300 RUM 3015 FP Energy at 2741 FPS with 210 Gr Accubond thats 25% more energy and 10% faster with a .30 Nosler 210 Gr vs. 300 WM190GR. [110] Ballistics for both rounds are similar and don't require weapons to be re-zeroed, but if they are the EPR can be slightly more accurate. It can also occur when the bullets pass through only minimal tissue, such as a limb or the chest of a thin, malnourished individual, as the bullet may exit the body before it has a chance to yaw and fragment. While the M855 had better armor penetrating ability, it is less likely to fragment after hitting a soft target. [11][5], Stoner contacted both Winchester and Remington about increasing the case capacity. [5], The Belgian 62 gr SS109 round was chosen for standardization as the second NATO standard rifle cartridge which led to the October 1980 STANAG 4172. Due to its greater length, the Remington case is about 25 percent more capacious than the Nosler case. Battlefield reports indicated that the M14 was uncontrollable in full-auto and that soldiers could not carry enough ammo to maintain fire superiority over the AK-47. [31], Proponents of the hydrostatic shock theory contend that the shockwave from a high-velocity bullet results in wounding effects beyond the tissue directly crushed and torn by the bullet and fragments. It is purely a big-game hunting cartridge that utilizes .338-inch bullets. The majority of failures were the result of hitting the target in non-vital areas such as extremities. The cartridge and rifle were developed as one unit by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). In this comparison I review ballistics data for the 28 Nosler and the 7mm Rem Magnum. [122] The Army attributes pressure and wear issues with the M855A1 to problems with the primer, which they claim to have addressed with a newly designed primer. The projectile contains approximately 95% Pb, 2% Sb, 3% Cu, and was designed for terminal ballistic instability. Thread starter tonyb; Start date Sep 18, 2017; Prev. It’s one hell of a round. [51][128][129] In July 2010, the Marines purchased 1.8 million M855A1 Enhanced Performance Rounds, in addition to millions of Mk318 rounds in service, as part of its effort to replace its M855 ammo. [125], According to US DoD sources, the Mk 262 round is capable of making kills at 700 meters. It is the exception. Half of small-arms attacks were launched from 300 to 900 meter ranges. [75] A replacement was needed, as a result, the Army was forced to reconsider a 1957 request by General Willard G. Wyman, commander of the U.S. Continental Army Command (CONARC) to develop a .223 caliber (5.56 mm) select-fire rifle weighing 6 lbs (2.7 kg) when loaded with a 20-round magazine. [6], According to STANAG 4172 and the official NATO proofing guidelines the 5.56×45mm NATO case can handle up to 420.0 MPa (60,916 psi) piezo service pressure. 28 Nosler, pushing a Berger 195 EOL at 3140 fps (RE33 powder). Though the M855A1 is more expensive to produce, its performance is considered to compensate. The .33 Nosler, the largest of the group, gives hunters significantly-increased velocities over the .338 Win. This pressure has to be recorded in a NATO-design EPVAT barrel with Kistler 6215 transducer,[21][22] HPI GP6 Transducer[23] or by equipment to C.I.P. There has been much debate of the allegedly poor performance of the bullet on target in regard to stopping power, lethality, and range. The civilian organisations C.I.P. Although all SS109/M855 types must be 62 gr. Firing several thousand rounds with such high chamber pressures can lead to degraded accuracy over time as parts wear out; these effects can be mitigated through a round counter to keep track of part service life. Like its stablemates—the .26, .28, and .30 Noslers—the .33 is based on the .300 Remington Ultra Mag case. [105], The M855A1 Enhanced Performance Round (EPR) was introduced in June 2010. In May of that year, a report was produced stating that five- to seven-man squads armed with AR-15 rifles had higher hit probabilities than 11-man squads armed with M-14 rifles. 33 Nosler New unprimed Brass. Combat operations the past few months have again highlighted terminal performance deficiencies with 5.56x45mm 62 gr. One primary advantage given by the round is its consistent performance against soft targets. how would it compare to the 338 edge. [5], During parallel testing of the T44E4 (future M14) and the AR-15 in 1958, the T44E4 experienced 16 failures per 1,000 rounds fired compared to 6.1 for the AR-15. for hunting deer and elk, but they are few except if you create a new Cartridge like the 26 Nosler. The RUM is a tad faster with the Energy going to the. Eugene Stoner of Armalite was invited to scale down the AR-10 (7.62mm) design. [61], The dimensional specifications of 5.56 NATO and .223 commercial brass cases are identical. It operates with a magnum bolt face. ya know the it shorter and all that i just would like the info for like a 300gr bullet. The required accuracy for Gw Pat 90 ammunition out of factory test barrels is 63 mm (0.72 MOA) for 10 rounds (100% radius measurement method) out to 300 m. The Gw Pat 90 cartridge dimensions are in accordance with the civilian C.I.P. Remington created a larger cartridge called the ".222 Special", which was loaded with DuPont IMR4475 powder. SS109/M855 cartridges fired from barrels under about 254 mm (10.0 in) in length do not have enough muzzle velocity energy to cause extreme damage that occurs only at terminal velocities of over 750 m/s (2,500 ft/s) on impact, reducing the wounding capacity. [18][19], The rifling twist rate for this cartridge is 177.8 mm (1 in 7 in), 6 grooves right hand twist, Ø lands = 5.56 millimetres (0.219 in), Ø grooves = 5.69 millimetres (0.224 in).
