Vihtavuori Reloading Data for rifle, handgun and shotgun loads
Ensure a successful and safe reloading result
Vihtavuori offers reloading data for nearly a hundred different handgun and rifle calibers and for shotgun loads, with numerous bullet options for all kinds of shooting disciplines and needs.
Please note that the data we offer on our website, in our newest Reloading Guide and in the Vihtavuori Reload App is all the official and safe load data we have available, and due to our Safety Policy we cannot suggest loads that we haven’t tested and published. Be sure to read all our safety instructions before you begin reloading. New to reloading? See also our How to reload guide!

How to use the reloading data
Our rifle and handgun data listings generally contain maximum charges which are not to be exceeded. In some instances starting loads are also listed. Currently our website contains all of the data we can supply. Be certain you use the correct data and the specific bullet weight shown.
By staying 5 % below the maximum powder charge weight, pressures will be reduced by about 10 % while velocities will be only about 3 % lower than listed.
Caution: When loading handgun cartridges it is vital to maintain the minimum cartridge overall length (C.O.L.) listed in the tables. Shorter overall lengths may double chamber pressures. Longer lengths are permissible so long as the functioning of the handgun will not be impaired.
The data in the loading tables were obtained at an ambient temperature of 68 degrees Fahrenheit and relative humidity of 55 %. The values obtained were under carefully controlled conditions and may vary from those obtained with your firearm, specific component lots, loading dimensions, and loading procedures. The maximum charges must NEVER be exceeded. Start loading with the starting load according to the loading data. If there is no indication of the starting load, use a 15 % lower charge than the listed maximum. When loading cartridges for which the listed charge is 10 grains or less, after firing 10 rounds at the minimum weight (15 % below maximum), increase charge weights by 0.2 grains and fire another 10 rounds. Repeat this procedure, if necessary, until you reach, but do not exceed the maximum listed charge. The same process is followed for heavier charges except that charge weights from 11 to 25 grains use increments of 0.5 grains. For charges over 25 grains increments of 1.0 grains will be correct. If even a single test round shows signs of excessive pressure discontinue the use of the load. Do not fire even a single additional cartridge. Seek qualified help before proceeding! The traditional sign of overpressure is a flattened primer.
When flattened primers start to occur, it is a definite warning that the charge should be reduced, quickly. Brass getting into the ejector and extractor cavities is a worse case. Blown out primers are worse still. If a case ruptures it may be a sign of a defective case or a truly lethal chamber pressure.
In case of overpressure signs it is wiser to back off, to be safe rather than sorry. Why risk potentially fatal injury? Better to stop shooting and immediately discard all such reloads. Read also the Reloading Safety Rules on pages 16 and 17. There are numerous factors which can change the ballistic performance of a load even when the data is followed exactly.
For example: The internal dimensions of a firearm can vary greatly even between two of the same make and model. Pressures can vary to extremes as different firearms are used. Each change in brand and even within different lots of a specific brand component can cause notable ballistic changes. Too, changes in ambient temperature can also cause ballistic altering pressures. Not every bullet of a given diameter and weight will produce alike pressure. Changes in case brand can also effect ballistics.
Pressure
There are numerous other causes of varying pressure levels. Therefore it is essential that the reloader be well versed in the methods of carefully working up a reload powder charge in small increments as outlined in the various reloading handbooks that are available from reliable sources. The data on this website is not intended for use by persons not thoroughly versed in such procedures. These instructions should be supplemented by a good recognized reloading handbook that offers all appropriate information.

At MAXAM we are proud to say that ours are the best smokeless propellants in the market: almost 150 years of experience attest to this. The quality of our powders is mainly due to the rigorous control of the characteristics to which it is subjected in order to achieve the expected speed and pressure.
Our gunpowder has a high stabilized nitrocellulose content that is gelled before being extruded and is given the proper porosity through a specific process. Finally, it is dried and subjected to a surface treatment until it achieves the fluidity required for its dosing.
Our powders range enjoys wide recognition and has been tested in manometric guns according to the rules of the Permanent International Commission (C.I.P.) for testing portable firearms. The exhaustive monitoring and supervision that we apply the entire manufacturing process, especially to achieve the perfect size and porosity, result in optimal pressure with a minimum of waste inside the barrel.
CSB, PSB+ and SSB+
Single base powder transformed into circular or square particles with medium-low gravimetric density. The CSB stands out due to its cleanliness and absence of waste and, together with the PSB, stands out with its great regularity and precision. On the other hand, the SSB + has been designed specifically for steel cartridges - perfect for hunting waterfowl.

They are shaped like small cylinders with a central hollow and have high gravimetric density. In particular, the GDB 111 is the only double-base gunpowder produced by MAXAM Outdoors.
In GDB 111 double- base gunpowder, nitroglycerin is also used as a fixed solvent. Our development and research teams allow us to continue creating new quality gunpowder for use in metal ammunition.

Zach Hinze
Zach, a resident of McCook, Nebraska, started shooting trap and hunting when he was 10. Soon, Zach was shooting skeet and fell in love with the sport. A couple months later, Zach shot USAYESS competition in Grand Island. Quickly he was attending weekly, monthly, and annual shoots, which included Nebraska state, USAYESS, and many more. Zach started attending national shoots in 2018, including Junior Worlds, Junior Olympics Nationals, and USAYESS Nationals.
Through shooting, Zach has met many people in the shooting community. Former lead pilot of the Blue Angel’s John Foley has reached been in contact along with Remington Mcbee and several others.
In addition to shooting, Zach plays plays baseball, basketball, football, and track & field. He volunteers as an alter sever at Mass on Sunday at church and is a member in the Civilian Airpatrol Program. He play trumpet in the Junior High Band and I am an honor roll student at St. Pat’s.
Zach has several friends that are getting into reloading shotshells because of Zach’s reloads. They are impressed by the light recoil and how cheap it is compared to buying new AA shells for practice or matches. All of them are asking their parents for shotshell presses now.

Having passed the corridor to the third compartment, I was completely alone, there were still n minutes before departure and I. Decided to use this useful time for myself: I put my makeup in order in front of the mirror, laid out my things, took out a book on the history of fashion and costumes.
