Get powder burn rate chart

30 BR cartridge. While still in its development phase, LT-30 was used to win numerous matches, even claiming a world record along the way. With a burn rate similar to 4198, this single-base fine grained powder is at home in many smaller capacity cartridges including the 6.5 Grendel and . 222 Remington.

The time it takes for this powder to burn through varies; powder burn rate refers to the time it takes for the smokeless powder to ignite.

Bullseye has the fastest burn rate of any accepted shotshell powder and, because of this, is the least elastic. It produces propellant gases faster than all other shotshell powders and therefore it runs very high pressures in everything except the lightest of loads.

Winchester 572 is a ball powder strategically designed to optimize a myriad of shotshell and handgun loads. First, 572 has the correct burn rate to create the famous 3-¼-dram equivalent, 1-¼ oz, (1330 FPS) 12-gauge factory Winchester load with any brand case!

In the mid-19th century, measurements were made determining that the burning rate within a grain of black powder (or a tightly packed mass) is about 6 cm/s (0.20 feet/s), while the rate of ignition propagation from grain to grain is around 9 m/s (30 feet/s), over two orders of magnitude faster.

Vihtavuori N170 is the slowest burning rifle powder in the N100 series (not taking 20N29 and 24N41 into account) and in fact one of the slowest canister-grade powders readily available from any manufacturer on the market.

It is likely the lower figure of 190 m/sec is the speed reached in a firearm, which means a 1" long powder charge could completely ignite in as little as 0.13 milliseconds.
