First, loosen the lug nuts on one wheel and raise the side of the trailer with a jack. Support the trailer with jack stands and then spin the wheel and listen to the trailer bearings. If the wheel spins freely and quietly, proceed with repacking the bearings. If you hear friction or a growling sound, you most likely have a bad bearing or spindle. If this is the case, take the trailer to a service center to get the trailer bearings replaced. Plus check out this super cool High-Visibility Trailer DIY.
After the meat has been in the pack four or five days, break the pack and give a second application of Sugar Cure, using about 2 or 3 lbs per 100 lbs. of meat. Then repack the meat in a different position.
After the meat has been in the sweet pickle brine about 5 days, remove the meat and brine and repack each piece of meat in a different position, again weighting it down, and pour the brine back over it. Overhaul in this manner every ten days during the balance of the curing period
When the position of the pieces is changed during overhauling, the pickle should be stirred up or poured out of the container and poured back. When pickle is left standing undisturbed, it becomes uneven, which causes the density of the curing ingredients in ratio to the water to be much heavier in one place than another. Removing the meat and pouring out the pickle, then repacking the pieces in a different position and pouring the pickle back over them thoroughly remixes the pickle so that cell parts have the same density. This allows the pickle to come in uniform contact with any spots of the meat that may have been pressed too lightly together.
Dies are generally sold in sets of two or three units, depending on the shape of the case. A three-die set is needed for straight cases, while a two-die set is used for bottlenecked cases. The first die of either set performs the sizing and decapping operation, except in some cases in the 3-die set, where decapping may be done by the second die. The middle die in a three-die set is used to expand the case mouth of straight cases (and decap in the case where this is not done by the first die), while in a two-die set the entire neck is expanded as the case is extracted from the first die. The last die in the set seats the bullet and may apply a crimp. Special crimping dies are often used to apply a stronger crimp after the bullet is seated. Progressive presses sometimes use an additional "die" to meter powder into the case (though it is arguably not a real die as it does not shape the case).
Dies for bottleneck cases usually are supplied in sets of at least two dies, though sometimes a third is added for crimping. This is an extra operation and is not needed unless a gun's magazine or action design requires crimped ammunition for safe operation, such as autoloading firearms, where the cycling of the action may push the bullet back in the case, resulting in poor accuracy and increased pressures. Crimping is also sometimes recommended to achieve full velocity for bullets, through increasing pressures so as to make powders burn more efficiently, and for heavy recoiling loads, to prevent bullets from moving under recoil. For FMJ bullets mounted in bottleneck cases, roll crimping is generally not ever used unless a cannelure is present on the bullet, to prevent causing bullet deformation when crimping. Rimless, straight wall cases, on the other hand, require a taper crimp, because they have headspace on the case mouth; roll crimping causes headspacing problems on these cartridges. Rimmed, belted, or bottleneck cartridges, however, generally can safely be roll crimped when needed. Three dies are normally supplied for straight-walled cases, with an optional fourth die for crimping. Crimps for straight wall cases may be taper crimps, suitable for rimless cartridges used in autoloaders, or roll crimps, which are best for rimmed cartridges such as are used in revolvers.
Cases, especially bottleneck cases, will stretch upon firing. How much a case will stretch depends upon load pressure, cartridge design, chamber size, functional cartridge headspace (usually the most important factor), and other variables. Periodically cases need to be trimmed to bring them back to proper specifications. Most reloading manuals list both a trim size and a max length. Long cases can create a safety hazard through improper headspace and possible increased pressure.
Bottleneck rifle cartridges are particularly prone to encounter incipient head separations if they are full-length re-sized and re-trimmed to their maximum permitted case lengths each time they are reloaded. In some such cartridges, such as the .303 British when used in Enfield rifles, as few as 1 or 2 reloadings can be the limit before the head of the cartridge will physically separate from the body of the cartridge when fired. The solution to this problem, of avoiding overstretching of the brass case, and thereby avoiding the excessive thinning of the wall thickness of the brass case due to case stretching, is to use what is called a "headspace gauge". Contrary to its name, it does not actually measure a rifle's headspace. Rather, it measures the distance from the head of the cartridge to the middle of the shoulder of the bottleneck cartridge case. For semi-automatic and automatic rifles, the customary practice is to move the midpoint of this shoulder back by no more than 0.005 inches, for reliable operation, when resizing the case. For bolt-action rifles, with their additional camming action, the customary practice is to move this shoulder back by only 0.001 to 0.002 inches when resizing the case. In contrast to full-length resizing of bottleneck rifle cartridges, which can rapidly thin out the wall thickness of bottleneck rifle cartridges due to case stretching that occurs each time when fired, partial length re-sizing of the bottleneck case pushes shoulders back only a few thousandths of an inch will often permit a case to be safely reloaded 5 times or more, even up to 10 times, or more for very light loads.
Similarly, by using modified case gauges, it is possible to measure precisely the distance from a bullet ogive to the start of rifling in a particular rifle for a given bottleneck cartridge. Maximum accuracy for a rifle is often found to occur for only one particular fixed distance from the start of rifling in a bore to a datum line on a bullet ogive. Measuring the overall cartridge length does not permit setting such fixed distances accurately, as different bullets from different manufacturers will often have a different ogive shape. It is only by measuring from a fixed diameter point on a bullet ogive to the start of a bore's rifling that proper spacing can be determined to maximize accuracy. A modified case gauge can provide the means by which to achieve an improvement in accuracy with precision handloads.
Such head space gauges and modified case gauges can, respectively, permit greatly increasing the number of times a rifle bottleneck case can be reloaded safely, as well as improve greatly the accuracy of such handloads. Unlike the situation with using expensive factory ammunition, handloaded match ammunition can be made that is vastly more accurate, and, through reloading, that can be much more affordable than anything that can be purchased, being customized for a particular rifle.
Case lubrication may also be needed depending on the dies used. Carbide pistol dies do not require case lubricant. For this reason, they are preferred by many, being inherently less messy in operation. In contrast, all dies for bottleneck cartridges, whether made of high-strength steel or carbide, and steel dies for pistols do require the use of a case lubricant to prevent a case become stuck in a die. (In the event that a case does ever become stuck in a die, there are stuck case remover tools that are available to remove a stuck case from the die, albeit at the loss of the particular case that became stuck.) Powder should always be stored in original containers since they are designed to split open at low pressure to prevent a dangerous pressure buildup, and any cabinet they are stored in should similarly prevent pressure buildup by allowing venting and expansion.
When previously fired cases are used, they must be inspected before loading. Cases that are dirty or tarnished are often polished in a tumbler to remove oxidation and allow easier inspection of the case. Cleaning in a tumbler will also clean the interior of cases, which is often considered important for handloading high-precision target rounds. Cracked necks, non-reloadable cases (steel, aluminum, or Berdan primed cases), and signs of head separation are all reasons to reject a case. Cases are measured for length, and any that are over the recommended length is trimmed down to the minimum length. Competition shooters will also sort cases by brand and weight to ensure consistency.
When a cartridge is fired, the internal pressure expands the case to fit the chamber in a process called obturation. To allow ease of chambering the cartridge when it is reloaded, the case is swaged back to size. Competition shooters, using bolt-action rifles that are capable of camming a tight case into place, often resize only the neck of the cartridge, called neck sizing, as opposed to the normal full-length resizing process. Neck sizing is only useful for cartridges to be re-fired in the same firearm, as the brass may be slightly oversized in some dimensions for other chambers, but the precise fit of the case to the chamber will allow greater consistency and therefore greater potential accuracy. Some believe that neck sizing will permit a larger number of reloads with a given case in contrast to full-size resizing, although this is controversial. Semi-automatic rifles and rifles with SAAMI minimum chamber dimensions often require a special small base resizing die, that sizes further down the case than normal dies, and allows for more reliable feeding. 2b1af7f3a8
