IMR® 4350

IMR 4350 is a medium- to slow-burn rate propellant and is the number one choice for the new short magnums, both Remington and Winchester versions. For magnums with light- to medium-bullet weights, IMR 4350 is the best choice.

IMR recommends always consulting for the most accurate, up-to-date data.

Available in 1-LB and 8-LB containers.
