Please check our FAQs first in case of questions.

  • Why do you discontinue the old site xxl-reloading.com?
    Our old site xxl-reloading.com was built on a technology that does not allow us to add new features. The old system makes it also very difficult for us to add new calibers, bullets, and powders - it just can't deal with the amount of data. We have received many suggestions over the last years on how to improve our site and what features to add. Unfortunately, this is impossible with the old system. Hence, we decided to launch a new website under xxlreloading.com (very similar, we know). We will continue to run the old website for a while to fulfill the access licenses that have already been purchased. New access licenses will be sold here.

  • What is "Filling Percentage", "Fill Rate" or "Load Density"?
    The Filling Percentage is the effective or usable combustion chamber volume occupied by the charge. This is also also named "Load Ratio" or "Fill Rate" and can be found in good reloading manuals. The Effective Combustion Chamber Volume is further explained here. The volume occupied by the charge is equal to the powder bulk density multiplied by the weight of the charge. The powder bulk density can be found in our powder/propellant database. Fill Rate = volume occupied / usable combustion camber volume Volume Occupied = charge x bulk density of powder Usable combustion camber volume = total case volume - volume occupied by seated bullet Important notice: Reloaders commonly try to operate with fill rates between 80% and 100%. Loads below 80% can be dangerous as they can produce very unsteady results. Loads above 100% are "press loads". They can also produce unsteady results and often dangerous pressures.
  • Powder criteria to be listed in load tables
    Powders listed for a specific caliber and bullet combination need to deliver loads that meet the following criteria: Achieve Fill Rate > 80% and < 100% while not exceeding allowed pressure (loads below 80% or above 100% are typically considered unsafe) Pressure for loads < 90% of Max. Standardized Pressure (more details and instructions) Propellant Combustion for rifle loads > 90% (lower values typically lead to unsteady results and strong muzzle flash) Propellant Combustion for pistol/revolver loads > 80% (lower values typically lead to unsteady results and stronger muzzle flash) For subsonic loads other / in addition: Muzzle velocity for barrel length below speed of sound Fill Rate > 50% Propellant Combustion > 75%
  • Can I deviate from the load data?
    Our load data (maximum load) contains at least a 10% safety buffer in regards to the maximum allowed pressure for a specific caliber . Hence, our listed maximum loads might be lower than loads proposed by powder or bullet manufacturers who do not include such a safety buffer. Experienced reloaders can exceed the maximum loads at own risk but should watch out for signs indicating that the ammunition is experiencing over pressure: Difficult extraction: If the cartridge is difficult to extract from the chamber, it could be an indication of over pressure. This happens because the brass casing expands more than it should due to excessive pressure. Case head expansion: The base of the cartridge case will start to expand if the pressure inside the case is too high. Primer flattening: The primer on the back of the cartridge will start to flatten if the pressure inside the case is too high. Bulging or cracking of the case: The cartridge case may bulge or crack if the pressure inside the case is too high. This is a serious issue that can cause the firearm to malfunction or even explode. Hard recoil: If the recoil of the firearm is significantly harder than usual, it could be an indication of over pressure. Else the following applies: The charge (weight of the load) is the key driver for the maximum pressure achieved by a reloaded cartridge. However, there more factors and specifically those that influence the free combustion chamber volume. The general rule is: The lower the free combustion chamber volume, the higher the achieved pressure for an identical load, hence cases with a lower volume generate higher pressure. Hence, cartridges with lower overall length (OAL) in the same caliber and with the same bullet also create higher pressure because the bullet seating depth is higher and the free combustion chamber volume is lower. We provide for each load the underlying cartridge specifications: Bullet Length, Case Length, Cartridge Length / OAL, Seated Depth, Case Capacity. Reloaders might deviate at on own risk from our load data if their cartridge specifications deviate: Bullet Length: with all other specifications being equal, greater bullet length allows for less powder Case Length (l3): with all other specifications being equal, greater case length allows for more powder Cartridge Length / OAL: with all other specifications being equal, greater OAL allows for more powder Seated Depth: with all other specifications being equal, greater seated depth allows for less powder Case Capacity: with all other specifications being equal, greater case capacity allows for more powder
  • What is "propellant combustion" or "powder burnt" or "z"?
    Propellant combustion is the solid-to-gas conversion of the powder. The metric "z" defines the percentage of the burnt propellant when the projectile leaves the muzzle. When optimizing a cartridge load through appropriate selection of components, combustion preferably ends before the projectile passes the muzzle. Achieving more than 95% of burnt propellant is considered to be a fair load. This improves energy utilization, ensures consistent results and somewhat influences the generation and appearance of muzzle flash.
  • The cartridge does not fit into my gun - is your C.O.L. data correct?
    We sometimes get notified that cartridges with an overall length (O.A.L or C.O.L. or L6) as specified on our pages do not fit into a particular magazine or gun. Please be aware of the following: Two institutions define cartridge specifications – the C.I.P. and SAAMI (see more here). They also define the maximum overall length of a cartridge in their technical data sheets. We respect these specifications and calculate our loads with an overall cartridge length which is always 1.5% lower than the maximum allowed length. Please contact the gun manufacturer if – based on these specifications – a cartridge does not fit into a chamber or magazine. In this case, the gun specifications are below the defined cartridge standards. You can deviate from our load data in such a rare case but please respect the following instructions.
  • Why do our loads differ from other sources?
    We sometimes get asked why out loads differ from other sources. Often it is then the case, that different components are compared. Please make sure you compare apples with apples. If loads still deviate, it mostly can be attributed to the following reasons: Safety Buffer Our load data (maximum load) contains at least a 10% safety buffer in regards to the maximum allowed pressure for a specific caliber. Hence, our listed maximum loads might be lower than loads proposed by powder or bullet manufacturers who do not include such a safety buffer. Cartridge Dimensions The charge (weight of the load) is the key driver for the maximum pressure achieved by a reloaded cartridge. However, there are more factors specifically those that influence the free combustion chamber volume. The general rule is: The lower the free combustion chamber volume, the higher the achieved pressure for an identical load, hence cases with a lower volume generate higher pressure. Hence, cartridges with a lower overall length (OAL) in the same caliber and with the same bullet also create higher pressure because the bullet seating depth is higher and the free combustion chamber volume is lower. We provide for each load the underlying cartridge specifications: Bullet Length, Case Length, Cartridge Length / OAL, Seated Depth, Case Capacity. Reloaders might deviate at on own risk from our load data if their cartridge specifications deviate: Bullet Length: with all other specifications being equal, greater bullet length allows for less powder Case Length (l3): with all other specifications being equal, greater case length allows for more powder Cartridge Length / OAL: with all other specifications being equal, greater OAL allows for more powder Seated Depth: with all other specifications being equal, greater seated depth allows for less powder Case Capacity: with all other specifications being equal, greater case capacity allows for more powder Suboptimal / Incorrect Manufacturer Data The load data of the powder and bullet manufacturers sometimes simply contains errors or is based on suboptimal inputs (i.e. too little powder leading to a too low fill rate, too much powder, physically not fitting into the case mentioned). We usually inform them and started to document them in our forum for transparency. Errors in our Data We can not exclude to make mistakes. For example, we sometimes get incorrect bullet measures from manufacturers. With that, our load data can be incorrect because the calculated seating depth and free case volume are incorrect. Please contact us if you believe our load data is incorrect and let us know which source you exactly compare with which of our data.
  • What is v or V(0)?
    v or V(0) is the bullet / projectile velocity when the bullet base passes the barrel muzzle - assuming the stated barrel length. In our load tables, V(0) is calculated with a standard barrel length of 23.6'' (60cm) for rifles and with 7.09'' (18 cm) for pistols/revolver.
  • What is the Effective Combustion Chamber Volume?
    The Effective Combustion Chamber Volume is calculated by subtracting the volume of the portion of the bullet extending into the case from the Maximum Case Capacity. The standard Maximum Case Capacity can be found in our cartridge database and is also provided by the safety standard. Image: Effective Combustion Chamber Volume indicated in red. Important notice: The actual case volume can deviate significantly from the standard value. We recommend you measure your cartridges before loading. This is how you can measure the case volume: After obtaining the weight of a dry empty case (with used primer in place), fill the case with water. Eliminate any air bubbles and bring water even to end of case neck. Reweigh water-filled case. Subtract dry case weight from water-filled case weight. This gives case capacity in grains of water, which is the standard unit of measure and listed in our database. The volume of the portion of the bullet extending into the case needs to be calculated based on the bullet type, specifically the base type of the bullet. With flat-base bullets, calculation of the area occupied by the bullet requires only bullet diameter and seating depth. With boattail or hollow-base bullets, base design needs to be considered.
  • Which saftety standards define the maximum allowed pressure and standard cartridge dimensions?
    There are two safety standards for (civil) ammunition established all over the world, which every handloader should know: In the USA, the SAAMI (Sporting Arms and Ammunition Manufacturers Institute, Inc., 555 Danbury Road, Wilton, Connecticut 06897) publishes and sponsors standards approved by the ANSI (American National Standards Institute) as voluntary industry performance standards for the use by commercial manufacturers. The C.I.P. (Commission Internationale Permanente Pour lEpreuve des Armes à Feu portatives, 45, Rue Fond-des-Tawes, 4000 Liège, Belgium) sets the standards for civil ammunition and weapons for European member countries. These standards are mandatory in countries having ratified the CIP Standard. By working together, the CIP and SAAMI are working towards the development of international standards. Maximum standardized pressures are listed in our cartridge database. Notice: We recommend to stay 10-15% below the maximum standardized pressure with any load to buffer for any variations. Only very experienced handloaders should exceed these thresholds at own risk.

  • Impact of barrel length on muzzle velocity?
    It has often been debated how barrel length impacts projectile velocity at the muzzle. The general principle is clear: the longer the barrel, the higher the velocity and the kinetic energy. The pressure created by the powder explosion accelerates the projectile in the barrel. The longer the barrel, the more time and distance is available to accelerate the projectile and, hence, the muzzle velocity is higher with increasing barrel length. While the general principle is clear, we took a more scientific approach to determine this relationship in greater detail: We simulated the muzzle velocity for changing barrel length for two calibers (.308 Winchester and .300 Winchester Magnum) and the 50 most common propellants respectively. We then put the muzzle velocity (Vo) at 600mm / 23.6 barrel length to 100% and indexed the other numbers accordingly to this reference. Finally, we aggregated the values for all propellants for each caliber by taking the average. The results are as follows: If you shorten the barrel length of a .308 Win from 600mm / 23.6 to 300mm / 11.8, your muzzle velocity reduces by 25% to 75%. If you shorten the barrel length of a .300 Win Mag. from 600mm / 23.6 to 300mm / 11.8, your muzzle velocity reduces by 32% to 68%. The results are different because the must suitable powders for a .308 Win are faster burning than the most common powders for a .300 Win Mag. Hence, the accelerate the projectile faster. With the increasing use of silencers, barrel lengths vary significantly more. Our load data therefore indicates the relevant ballistic information for different barrel lengths.
