Looking at this from a different perspective, that's 4.8 inches per mph of wind. Using RL 17, you can get 2950 fps fairly easily in a standard (non-improved) .284 Win case. They’re both great cartridges, but I’d probably lean towards the .270 Winchester. For all intents and purposes, we can say that the two cartridges have the same ballistics. The Lyman 50th Edition (p197-198, 199-200, 214-216, 219-220,257-259, 260-262, 288-289, 294-295) and Hornady 10th Edition (p351-359, 356-359, 406-411, 412-416, 564-573, 574-585, 637-639, 659-664) reloading manuals were used as references for the history of the cartridges. You can often find used BAR Safaris for $650.00 or less in superb condition. His reloading methods, described in his Gun of the Week feature, have produced amazingly good ammo.
We certainly expect RL 17 to deliver impressive velocities--the question remains, will it match the accuracy and low ES/SD of powders like H4831sc, H1000, and RL 25? High power ace Jim Hardy fields a .284 Shehane in long-range matches.
But my .284, with its high-BC Berger 180s, shot inside both the 6.5 and 300 by at least 3" every time. We can use a simpler method to get fast and accurate wind holds. Charles Ballard has had spectacular success with the .284 Win using a 32" barrel. Whether you want an explosive ballistic-tipped bullet, high sectional density for penetration, or a bonded core for high weight-retention, you will find a 7mm bullet design that does the job exceptionally well. Are you just itching to take a rifle chambered in one of these cartridges on a hunt? The 7mm SAUM is an impressive long-range performer. The 180 VLD doesn't take up too much case volume when loaded to magazine length, either. It is worth remembering that the majority of authorities agree that recoil of over twenty foot pounds will cause most shooters to develop a serous flinch, which is ruinous to bullet placement (the prime component of killing power). The toroidal (donut shaped) bolt lug design ensures that both lugs consis- tently engage the receiver when the bolt is closed. "I will say this about the 7mm SAUM versus the straight 7mm WSM. One of the benefits of working with a local gunsmith was the ability to control and access the project. In 1909 the British Textbook of Small Arms stated that 15 ft. lbs. Unfortunately, the future isn’t looking very bright for that cartridge right now. Q: How does the 7 WSM stack up in your mind? Is it significantly more accurate than the .300 Winchester Magnum?
Thanks. Necking-Up vs. Necking-Down However, other cartridges, like the 6.5 Creedmoor and .308 Winchester (which have overall lengths of 2.825″ and 2.81″ respectively), are about a half inch shorter and will therefore fit into what’s commonly known as a “short-action” rifle. In the shooting sports we call that reaction recoil or "kick." ? This simply isn't true. Good velocity, near 100% fill density with RL 15. Jim reports: Field Test (October 26): "I have been testing RL-17 in my .284 Shehane rifle with a Barnard ejectorless action. I used a Proof Research all-steel 26-inch heavy Palma contour barrel spun at 1:8-inch twist attached to the action with a Savage barrel nut.
Experiment with shooting the VLDs OFF the lands. Even though Ric had great success in the past with a 300 WSM that I had built, the 7mm WSM was the caliber of choice for the Twins.
BOSS tuner, Winchester, Remington, Norma and Lapua brass. In this segment of “Cameras Don't Lie,” competitive shooters Patrick Sweeney and Jim Tarr head to the range to put the vaunted loads on record, and then consider the footage. I prepped and sorted my cases, and have no problems with accuracy using Winchester brass. That's big news for 7mm fans. I haven't done much work with the 175s I have loaded up. In this section we cover both the "normal" 7mm WSM and the 7mm-270/300 WSM variants. This is not a hard and fast rule, but it is a common occurrence with these two particular cartridges. For that reason, the .338 Winchester Magnum is probably the closest comparison to the .325 WSM that’s in common use in North America. I have a bubble-level mounted on the scope rail. About the accuracy--people say say that magnums are not supposed to shoot that well. Meters great. While the 180gr VLDs, typically, work best seated .010" or more into the lands, some shooters have obtained excellent accuracy jumping their bullets .020" or more. This is illustrated in the table below comparing Federal Premium and Hornady factory ammunition loaded with 140gr Trophy Bonded Tip (.430 BC) and 162gr ELD-X (.631 BC) bullets in 7mm WSM and 7mm Rem Mag.
How do the game mix and terrain dictate your selection of a rifle? My 7mm STW is launching the 168's at 3340 out of a 28" barrel. 10:30 a.m., up the mountain I go to my 1000-yard spot. However, H4831sc has a reputation for great accuracy and it can deliver super-low ES and SD in properly prepped brass. The exact size of the rifle action (which includes the locking bolt, firing pin, etc.) The plastic-tipped 162gr A-Max has proven to be very accurate, with an impressive 0.625 BC. I wish I had tried the SAUM before I committed to the 7mm WSM, it would have saved me a bunch of money on gunpowder so far. Among the 7mm short action Magnums, most interest had focused on the 7mm WSM until very recently. But most of those shooters really have a hard time in wind. After firing the cases once, I clean them all up and make one pass on the neck turner just to "clean" the necks to a consistient diameter. This new propellant is nearly ideal for the .284 Win shooting the heavy 7mm bullets. All the metal is Teflon-coated in Mil-Spec OD Green.
