What type of powder is H4350?
extruded propellant
H4350 is an extruded propellant in our Extreme series that has been one of our most popular powders with shooters for decades. During that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to hot and cold temperatures.
What is single based powder?
Single-base smokeless powder is made from nitrocellulose. Double-base smokeless powder is a combination of nitrocellulose and nitroglycerin. The performance difference between single- and double-base powders is not set in stone, and it’s hard to quantify because of other variances in powder makeup.
What is a double-base powder?
Definition of double-base powder
: an explosive powder or propellant that contains nitrocellulose and nitroglycerin as the essential components — compare single-base powder.
Is H4350 powder temp sensitive?
You can see Hodgdon H4350 had the least variance in muzzle velocity, with just 25 fps over the 115° swing in temperature! That is very, very low. Hodgdon Varget was the second least temperature sensitive powder in this test, with 46 fps of variance in muzzle velocity between temperatures of 25° F and 140° F.
What powder is best for 6.5 Creedmoor?
For 6.5 Creedmoor, powders like H-4350 are optimal for mid to heavy bullet weights, and powders like Varget are great when using lighter bullets. RL-15, Norma URP, and Reloder 16 are also used frequently with 6.5 Creedmoor.

What is single-base smokeless powder?
< Back to home. Smokeless propellant powder which has colloided nitrocellulose as its main ingredient, and contains no other major energy-producing component. The nitrogen content of the nitrocellulose is usually between 13.1% and 13.2%.
What is the difference between single-base and double base propellant?
In propellants, there are single- and double-base types. Single-base propellant has its energetic component being only nitrocellulose. To get higher energy content into propellant and therefore more performance, nitroglycerin (NG) is added to the nitrocellulose. Propellant that contains NG is called “double base.”
What type of gunpowder should be used in a cartridge?
Flake Powder
This type of powder has granules that are shaped like tiny discs. They are essentially powder that is extended into a tube shape and cut into tiny sections, almost like cutting a very tiny summer sausage. They are used mostly in handgun and shotgun cartridges.
What is the most temperature stable rifle powder?
The testers measured the velocity of the powders over a wide temperature range, from 25° F to 140° F. Hodgdon H4350 proved to be the most temp stable of the four powders tested.
What powder is equal to Varget?
Best Varget Substitute
The closest equivalent to Varget in the UK is Ramshot TAC. Ramshot covers a range of six rifle and three handgun calibre powders.
What is the least temperature sensitive rifle powder?
IMR 4166 and Varget were the least sensitive powders to temperature-induced bullet velocity changes for 77 grain MatchKing bullets between 34 and 129°F. AR-Comp had the least temperature sensitivity between 68 and 131°F and the smallest standard deviations in velocity.
Does cold affect gunpowder?
Several months of exposure to high temperatures (above 100 degrees F) can substantially shorten the life and the expected performance of propellant. Cold temperatures have little effect on propellant.
What temperature should Gunpowder be stored at?
What is the estimated shelf life of gun powder? The estimated shelf-life of Vihtavuori gun powders is a minimum of 10 years, if stored and sealed in its original containers at a temperature of circa 20°C/ 68°F and a relative humidity of 55-65 %.
