What is the slowest burning powder?

Vihtavuori N170
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.

What is the slowest burning smokeless powder?

AAC-8700 is surely the safest and slowest, while DuPont IMR-7828 produces higher velocities without the loading density problem. We rated these slow-burning powders by their burning time. You can’t actually measure the burning time of a gun powder.

Is H4350 slow burning?

We also now have a situation wherein powders having the “same” numerical designation are available from several different sources. Probably the best example of this is the slow-burning single-based rifle propellant known as 4350….be listed elsewhere as:

Hodgdon H4350 Extreme H4350 EXT
Vihtavuori N170 Viht N170 N170

What powder is like IMR 4350?

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.

Versatility with uniformity and accuracy.

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.
