The real number is .75 mils, but, hey, what's .05? While there are rounds for both cartridges that better than others, the 7mm Mag rounds, in general, had better velocities, BCs, and trajectories with it most pronounced as the rounds moved downrange. As you’d expect from the fact that the two cartridges are very similar in overall size, the ballistics of the 7mm Rem Mag and .300 Win Mag are pretty similar. Give a Gift   The next option is the .300 Norma Mag., which offers even better performance than the .300 Win. The story of a confederate sniper’s revenge and an exclusive look at his rifle. In order to obtain that performance from a .30 caliber, I would need to jump into the .300 Win. and 7mm-08 Rem. One of the main benefits of the 7mm is the wide variety of heavy bullets with high BCs and low form factors, both desirable for efficient trajectories. Nosler and Hornady load both 7mm Remington Magnum and .280 Ackley ammunition; looking at their data you’ll see a difference of 90 to 100 fps between the two, with the belted 7mm Magnum giving the higher velocities (with a 162-grain Hornady ELD-X, the 7mm Mag. There were also several shooters using the 7mm SAUM, also known as the 7mm Remington Short Action Ultra Mag, including one in the top 10 and another in the top 25.

Great care has been given by Hornady engineers to develop superior, match­-accurate hunting loads that allow the ELD­-X ® bullet to achieve its maximum ballistic potential. .652, zeroed at 230 yards. It says that at around the halfway point of 250 yards the bullet will have slowed by 500fps. 375 RUM. For some, this has been asked and answered already. 378 WBY Magnum.

However, for a heavier-hitting bullet to fill the hunting role, most shooters jump right into the .30 caliber offerings, which have ideal characteristics except one: stout recoil. It is all because of high ballistic coefficients and velocities on the 6.5mm bullet from the SAUM cartridge. 7mm STW. Hot on the heels of the .300 WSM, Remington countered with the .300 Remington Short Action Ultra Magnum—or RSAUM for short—based on a shortened version of their 1999 .300 Remington Ultra Magnum cartridge.

It was designed specifically for the Remington Model Seven Magnum rifle, and intended primarily for long-range hunting use. Since the 6.5-284 Norma is nominally a short-action round (COAL 3.228,) let’s revisit the ballistic chart I used in a previous blog comparing the 308 Win. With a 7mm SAUM you can come very close to matching the 7mm Rem Mag with bullets in the 140-160 weight range. By Chuck Hawks. 7mm Reloading Components.

If you compare the ballistics on these two calibers it will show you the faster 140 grain 6.5mm will outperform the slower heavier 7mm bullet. 7mm RUM. For example: 800 yard target = 8, and a full value wind of 8 mph means I need a wind hold of .8 mils. SAUM shows that 56.0 grains of IMR 4350 powder will drive their 140 grain bullets to a MV of 2943 fps, and 60.0 grains of IMR 4350 is good for a MV of 3146 … IMO- If your shooting past 1000 yards the 7mm is a better choice.

The 7mm shoots .284-inch diameter bullets through bores .28-inch across, but only two use this Imperial measuring system in their titles: .280 Remington and .284 Winchester, both excellent but under-rated “standard” velocity cartridges. I've got a Remington model seven 6.5 saum with a 26" bartlein 3b fluted in the works. Safari. To save space, the following abbreviations are used in the table below: Wb = Weight of bullet (in grains); MV = Muzzle Velocity (in feet per ... 7mm SAUM (150 .456 +2.5" +2.3" 3"@150 305 . Both of those calibers have significantly higher recoil, and the gains are only .1 mil less for the same 10 mph full value wind. Running some numbers, I can identify that if I take my range to the target in hundreds of yards and use a wind speed constant of 8 mph (full value), my mil holds line up pretty well with the range in hundreds of yards. This is compared to a 7mm SAUM which does about 2800 – 2900 fps with a 180 grain bullet. The wide field of view and clean, crisp dot makes it easy for users to find and track the dot in both target and competitive shooting applications. Norma brass is amongst the best avail- able and is incredibly consistent with zero cull rates. However, to achieve its small velocity advantage, the larger 7mm WSM had to burn 7-10% more powder than the 7mm SAUM. Average FPS: 3044. I debated on trying to fit a 7mm saum into the 3.850" mag box with 162gr bullets. My first 7mm SAUM rifle is a Rem M700 built by Greg Tannel in a McMillan A5 stock with a 1:9″ twist, 28″ Krieger barrel.

I elected to use Alpha Industries' Type 4 magazine designed for the .300 WSM-sized case. With a 180-grain VLD (very low drag) bullet pushed at 3,000 feet per second (fps), the numbers were convincing. I chose to run Berger 180-grain VLDs as the do-it-all competition/hunting bullet. Trajectory Table Shows 7mm-08 Defeats 308. It … Recoil: 2.07. As with most of the 7mm heavies, the 7 SAUM is very efficient in the wind. A Remington 700 footprint is the foundation for this engi- neering marvel.

So far, I'm very pleased with the 7 SAUM's performance. These claims are valid if the short magnum cartridges are fired in 24 inch barrels, the same length as the barrels of most 7mm Rem. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. This bullet at 500 yards still has speed and stopping power traveling some 2143fps and carrying either 1427lbs energy (140gr) or 1603lbs energy (150gr). However, to achieve its small velocity advantage, the larger 7mm WSM had to burn 7-10% more powder than the 7mm SAUM. My 7mm SAUM is chamber in a 700 Remington rifle with a 24 inch barrel. One of the benefits of working with a local gunsmith was the ability to control and access the project. On an 18-inch wide target at 1,000 yards, I have to call the wind within 1½ to 1¾ mph of its actual velocity to get a hit if I'm aiming at the center of the target. This hasty wind hold method works well out to about 1,400 yards with my 7 SAUM, and the 8 mph constant will put my wind holds consistently .1 mil under the actual values, which is close enough for me. and exactly the same claim is made for the 7mm WSM. Once we start looking at the wind from this point of view, it can give us an immediate indication of how accurate we need to make our wind calls for a given target size. *Casing image above is an artist rendering and not a real photo of 7mm … Red vs. Green Lasers: Visibility in Bright Light, Pulsar Thermion XG50 Thermal Riflescope - First Look, Pairing Barrel Twist Rates with Bullets for .223 and 5.56 NATO, First Look: Springfield Armory Model 2020 Waypoint Bolt-Action Rifle, The Story of Civil War Sniper Jack Hinson and His Rifle, Guns & Ammo TV: Hornady Critical Defense Rifle Ammo, Guns & Ammo TV: 6.5 Creedmoor vs. .375 H&H, U.S. Military Adopts Hornady's New Cartridge: 6mm ARC, Guns & Ammo TV: Cameras Don't Lie: 9mm vs .45 ACP, Trijicon's New Specialized Reflex Optics (SRO), Cameras Don't Lie: Subsonic 9mm vs. .300 Blackout.
