It has a jacket and core that are designed to expand even at velocities as low 800 fps. Hornady. The object behind the roll crimp is to firmly grip the bullet, in order to provide better ignition and reduce the possibility of the bullets being “pulled” under recoil. The factory outlet hours are Monday – Friday 9:30 a.m. to 12:00 p.m. and 1:00 p.m. to 4:30 p.m. CST. Think of a reloading manual as a report. Maybe, but perhaps not. For reasons of safety. No more than necessary to remove all signs of any belling and to lay the case mouth flat against the bullet. Taper crimping, on the other hand, merely removes the case mouth flaring left by the belling/expanding operation. Despite its nomenclature, the .221 Fireball requires .224” diameter bullets. You should stick with the data in your handgun manual while loading your pistols and use your rifle manual when loading the rifles. For the hunter, this means more energy, flatter trajectory and less wind drift. Now, take into consideration variations in components. Switching them around randomly can lead to some serious pressure problems. Reducing the case length slightly, the loading was changed to a 150 grain bullet at 2700 fps. It’s not unusual for two barrels of the same manufacturer, using the same loads, to vary 100 fps or more. Cooler temperatures can lower velocities and warmer temperatures can increase them. This is often a good way to introduce a new shooter to the game. .30-06 (Winchester Rifle Data) 17.30-06 (WWI and WWII American Bolt Actions) 10.30-06 Ackley Improved: 22.30-06 Ackley Improved (P.O. Case life will vary from one firing to a point where you realize they are never going to expire. While a modern Colt SAA or replica may be made of better steel than their ancestors, they are not nearly as strong as a Ruger Blackhawk or Freedom Arms revolver, despite their physical resemblance. #7430 .264” 130 gr. Refer to the powder burning rate charts and the reloading data table for a This may be as simple as changing bullet weights or altering your load to your hunting situation. Not as a general rule. We have always maintained that there is no such thing as a “universal” bullet, one equally well suited to all tasks. There’s a lot of variables at work here, so the fact that your velocities are different is hardly surprising. Using the lightest bullet at the minimum velocity will normally give the least recoil of any combination. Fireforming was accomplished without mishap. No. powderi / velocity g 2400 2500 2600 2700 2800 2900 h4895 32.0 33.6 35.1 36.7 When stored in such an environment, cartridges kept in sealed containers will last the best part of a lifetime. Think about the sharply pointed Spitzer nose of one cartridge in a tubular magazine, resting in contact with the primer of the cartridge in front of it in the magazine. As a general rule, roll crimps are recommended for most revolvers, rifles using tubular magazines and situations that call for an extremely high bulletpull. Interested parties should not rely solely on this information and should directly contact a ballistic technician should they find the information presented here to be unclear. Penetrating ability, expansion characteristics and even profile must be considered when designing a hunting bullet. Think about the .218 Bee, the .219 Zipper, the .220 Swift and the .225 Winchester cartridges. Whatever you do, keep your wife’s rolling pin off the reloading bench, and don’t alter that powder! Since this is highly polished, it requires no lube and will eliminate one step in your reloading. The .357 is at its best with slow-burning pistol powders such as H110 and WW 296. The Colt (and SAA replicas) have relatively small cylinders, compared to the Ruger and Freedom Arms revolvers. 111 0 obj <>/Filter/FlateDecode/ID[<39778EC5EF074A3F7D7085F610E6DE5D><33023F31EB583A45AD3EBCA00191F82D>]/Index[91 36]/Info 90 0 R/Length 99/Prev 225368/Root 92 0 R/Size 127/Type/XRef/W[1 2 1]>>stream Different nose profiles may require some adjustment to their over-all-length (OAL) for proper feeding and functioning. NOTHING stops this bullet. In loading for the 6.5x55mm, bear in mind that the older military rifles were designed for pressures in the 45,000 psi range. In short, anything you can do to make cases more uniform, right from their first firing is an advantage. Its longer sight radius makes it easier to achieve and maintain proper sight alignment. A quick trip to a competent pistolsmith will put matters straight. This constant working of the brass will harden it to the point that it develops splits in this area. Free floating a barrel is simply an attempt to eliminate a potential source Load your Garand with only those medium-burning powders that are compatible with its gas system. Vihtavuori offers new load data in the following calibers: 30-06 Spring. First, clean each chamber thoroughly. ), a different lot of, well… you get the idea. When using military cases, always check the capacity against the last lot of commercial brass you were using to avoid any potential problems, and adjust the load accordingly. It delivers a velocity range that makes all sorts of sense for hunting common animals at … Norma Loading Data .30-06 Springfield. A longer, heavier bullet in any diameter needs a faster twist to be properly stabilized. While care has been taken in its preparation, no responsibility is accepted for the completeness or accuracy of the information presented here. Two factors limit OAL–magazine length and throat length. Not without reducing your load by 5%. Almost instantly, the case relaxes its grip on the chamber walls as the pressure starts to drop, allowing the case to be extracted. This is probably the single most common cause for case loss. I have stumbled upon it twice, once each for .223 Remington and 8x57 Mauser and downloaded the .pdf. © 2020 Sierra Bullets With their terrific camming power, a cartridge can be easily forced into the chamber even if it is a bit snug. It just isn’t a suitable choice. If the bullet has arrived on target accurately, its job is done at that point. h�bbd``b`��@�q�`kš@��H�%�X�@�= D\)y No. Even coarse grain stick powders can be thrown close enough to produce excellent accuracy. %%EOF This is exactly why we produce such an extensive line of bullets in each bore size. Reaming the inside is a procedure done when necking a larger caliber down to a smaller one. As the ranges increase, so does the advantage of the higher ballistic coefficient. For more information please call 800-223-8799 or email us at sierra@sierrabullets.com. When it comes to the release of new projectiles, reloading data can be difficult to find. By using the lightest bullet weights shown, or by using the load showing the minimum listed velocity. JSP point makes good defense against a bear. � Rš$8�A��@�+$Q$���^��``����8�3@� ^�C Sierra Gamechanger Load Data. Good on ya on2it good to see some awesome resources popping up maybe this could be stickied to the top of the page for everyone to refer to without having to do a site search for it. Copper showing in small smudge points indicate contact. (888) 223-3006 In some instances, primers can be a good indication of pressure. As a result, when the same load was fired during the summer with much higher temperatures, the powder was easier to ignite, causing pressures to climb too high. Using a slow-burning powder such as 4831, even if the load develops relatively mild chamber pressure, will still give excessively high port pressures. Yes, you usually get better accuracy when you barely touch the rifling, but not always. Diam inch mm. of IMR4350, Winchester or Remington Brass, Winchester LR or Remington 9-1/2 LR Primer . Not unless you are working at maximum loads for your rifle. High pressure will set the cartridge back into the bolt face, causing the brass to flow into the ejector hole and leaving a shiny spot on the case head. Hunting bullets must perform in a certain manner after impact. The name doesn’t have to relate to bullet diameter at all, since .224” diameter bullets are correct for all of these cartridges. Pistol and rifle primers have different cup hardness and are made to operate at different pressure levels. No. Because when you broke the powder up, you exposed parts of the kernels without a deterrent coating and changed its geometry. If the cartridge were lubricated, the case wouldn’t be able to grip the chamber walls, allowing it to slam back sharply against the bolt face. Next, assemble a dummy round with the chosen bullet to the exact OAL you tested in the magazine. For example, you want to use Win 231 in your 7mm Remington Magnum, because you have several pounds on hand for your .45 ACP? Your cases may vary within the same brand as to both volume and strength. For one reason, the metal used in the old guns isn’t up to the standards of that used in modern firearms. Since the remaining velocity at 100 yards will be well above this, expansion will be reliable at any practical handgun range. 126 0 obj <>stream Polishing the feed ramp and adjusting the magazine lips may solve the problem. Another cause could be trying to seat the bullet and crimp in the same stage. It uses .363” diameter bullets, while the more widely known 9mm Luger uses .355” diameter bullets. You may not be belling the case mouth quite enough to get the bullet started smoothly. The following data was developed in a Hall actioned rifle that has a number of barrels chambered for different cartridges, ranging from the 22-243 Improved, 308 Winchester, 30 Special and the 30-06 Springfield. Moving the case to the crimp station, run the press up to the top of its stroke. Open the bolt and carefully eject the dummy round. They are another cause of hard extraction. If we were to mount two Smith & Wesson .38 Special revolvers, a six inch and a two inch, in a machine rest, both would very likely display about the same level of accuracy. If we’re talking about a really drastic change in seating depth, then the load should be backed down, and worked up again with the new seating depth. BTW I have noticed that the Sierra load manual states H4831SC as accuracy load for the 30-06 and 150/155gr bullet.
