Federal and Nosler make loads for 7mmSTW: http://www.midwayusa.com/ebrowse.exe/browse?TabID=3&Categoryid=7948&categorystring=653***690*** Here's how Gun Tests compares the two you ask about: http://www.gun-tests.com/performance/7mmstwedge.html How Do They Compare? Of course, our primary interest in this space is to match up the two new kids on the block, the 7mm STW and .30-378 Weatherby. Nonetheless, we also wanted to add context to the comparison by adding data for the well-known 7mm Remington Magnum. Many hunters like the 7mm Remington Magnum as a long-range, flat-shooting deer-rifle cartridge. Remington offers a 140-grain load that uses the same bullet as the new 7mm STW, so it seemed natural to run the numbers for it as we gauged the performance of the factory wildcats. Using data from Remington’s 7mm Remington Magnum factory load, we find that the 7mm Remington Magnum has a point-blank range (assuming a 6-inch zone) of 306 yards with a 262-yard zero. The 7mm STW with the same bullet has a point-blank-range of 322 yards with a 275-yard zero. The big .30-378 with Weatherby factory loads uses the Barnes 180-grain X-Bullet. It has a point-blank range of 340 yards and a zero of 290 yards. At the 7mm Remington Magnum’s limit of point-blank-range, the 7mm STW is only about 1.5 inches low while the .30-378 Weatherby is about half that. At 400 yards the 7mm Remington Magnum is 13.21 inches below the line of sight, the 7mm STW is 10.58, and the Weatherby is only 8.04 inches, or about where the 7 Mag. is at 355 yards. At 500 yards the 7mm Remington Magnum is 30.84 inches low, the 7mm STW falls 25.83 inches, and the .30-378 drops 20.41 inches below the line of sight. The 7mm Remington Magnum has 2,240 foot-pounds of energy at 200 yards, 1,878 foot-pounds at 300 yards, 1,564 foot-pounds at 400 yards and 1,292 foot-pounds at 500 yards. In contrast, the 7mm STW has 2,521 foot-pounds of energy at 200 yards, 2,123 foot-pounds at 300 yards, 1,776 foot-pounds at 400 yards, and 1,475 foot-pounds at 500 yards. Both pale in comparison to the .30-378, whose big bullet has 3,709 foot-pounds of energy at 200 yards, which is more than either of the other two started with. At 300 yards it’s carrying 3,266 foot-pounds, which is still more than the 7mm Remington Magnum had at the muzzle. It crosses 400 yards with 2,865 foot-pounds, and at 500 yards the bullet is charged with 2,506 foot-pounds of energy, more than the 7mm Remington Magnum has at 140 yards! Looked at another way, using a 200-yard zero the 7mm Remington Magnum is 6.12 inches low at 300 yards, 18.01 inches low at 400 yards, and 36.84 inches low at 500 yards. With the same 200-yard zero, the 7mm STW is 5.36 inches low at 300 yards, 15.82 inches low at 400 yards, and 32.38 inches low at 500 yards. The .30-378 Weatherby is 4.65 inches low at 300 yards. The 7mm Remington Magnum crosses that line about 285 yards. The Weatherby is 13.56 inches low at 400 yards, a line the 7mm Remington Magnum hits at just past 360 yards, and the Weatherby is 27.33 inches low at 500 yards, which puts it on the same level with the 7mm Remington Magnum, around 450 yards.
