What Is a Powder Burn Rate Chart? 

A powder burn rate chart, as its name suggests, is a graphical representation which provides information about the burning rate of various gunpowder types. The burn rate is a measure of how rapidly a given amount of powder will combust when ignited. It's a pivotal aspect influencing both the pressure and velocity generated by the ammunition.

Importance of powder burn rate

Knowing the burn rate is vital for safety and effectiveness. A powder with a faster burn rate generates higher pressure and velocity, potentially damaging the firearm or causing an explosion. In contrast, a slow-burning powder may not produce sufficient pressure or speed, rendering your firearm ineffective.

How to Fill Out Powder Burn Rate Chart PDF

Filling out the form is straightforward. You simply identify the powder in question and plot it on the chart according to the manufacturer's burning rate:

  1. The form contains various sections named: Vihtavuori, Reload Swiss, Norma, Hodgdon, IMR, Winchester, Rottweil, Accurate, Lovex by Explosia, Vectan, Alliant, Ramshot, and B&P. You will find each of these sections identified by their respective names.
  2. Start with the first section named 'Vihtavuori'. This section helps you compare the burn rates of different powders made by the Vihtavuori company. Review each of the powders listed and mark the column corresponding to the powder you're using or plan to use.
  3. Move to the next section titled 'Reload Swiss'. Similar to the previous section, review each listed powder and mark the respective box for the powder you're using.
  4. Repeat this process for 'Norma', 'Hodgdon', 'IMR', 'Winchester', 'Rottweil', 'Accurate', 'Lovex by Explosia', 'Vectan', 'Alliant', 'Ramshot', and 'B&P' sections respectively.
  5. The form's purpose is to help you visualize burn rates from faster burning ones (top of the list) to slower burning ones (bottom of the list). Make sure to fill in the respective boxes aligning with this concept.
  6. After you've filled all sections with the appropriate markings, review the form before final submission to ensure all data is accurate.
  7. If everything looks correct, submit the form. 

Remember, the form does not dictate which powder to use but simply provides comparative data to help you decide which powder suits your needs best.

Understanding the powder burn rate chart form

While comprehending a powder burn rate chart can seem daunting at first, armed with a little know-how, you will find it pretty straightforward to fill out this form on your own. The chart typically lists the powders in order from fastest to slowest burn rates. The powders at the top have the quickest burn rates while those at the bottom are slower.

Remember, even though certain powders may be adjacent on the chart, it does not necessarily mean they can act as substitutes for each other. Burn rate alone should not be the grounds for powder substitution. Always stick to the manufacturer’s recommendations.
