Is black powder fast or slow burning?
A ‘low’ explosive, black powder deflagrates (burns) at subsonic rates where as high explosives detonate or burn at supersonic speeds. The problem with black powder is that when burnt with only about 40% – 45% converting to gas, the majority is left in the barrel (fouling) while the rest leaves the barrel as smoke.
What powder is closest to imr4350?
Available now as the original IMR 4350, Hodgdon’s H4350 and Accurate Arms’ 4350, the potential for confusion is obvious. Other powders sharing this same situation are 4227, 4198, 4895, and 4831. Each of these powders is available from both the Hodgdon and IMR powder companies.
What type of black powder burns the fastest?
Black powder is produced in several different grades of increasing grain size (coarseness): FFFFg, FFFg FFg, and Fg. Smaller grain size powder is easier to ignite and burns faster. FFFg and FFg are the two most common grades in use today.
What burns faster black powder or smokeless powder?
Smokeless powder is also a low explosive but has a higher flash point and produces greater pressure. If ignited in the open, it will burn much slower than black powder. Putting smokeless powder into a black powder gun risks an explosion in the barrel.
What kind of pistol has the best powder burning rate?

Are burning rates of different powders linear?
It must be clearly understood that burning rates are not linear. There may be several powders which have very nearly the “same” relative quickness listed together, with the next listed powder being significantly different.
Do “fast” and “slower” burning powders really burn faster?
As a result, it is quite possible for a “fast” lot of a “slower” burning powder to appear to be somewhat “faster” than a “slow” lot of what would normally be thought of as a faster burning propellant. This situation, in effect, would cause these two powders to switch positions in the following chart.
Why does the burning rate of a smokeless propellant vary?
It should also be understood that the burning rate of any given powder can vary substantially when different cartridges are being compared. Smokeless propellants are organic compounds, and are subject to lot-to-lot variations that are unavoidable during the manufacturing process.
