I have one 8# keg of IMR  SR4756 for sale.
Never used this one, so deciding to get it out of the safe to make room for ones I do actively use.

IMR SR 4756 is fine-grained, easy-metering propellant has long been a favorite of upland and waterfowl handloaders. Top velocities with great patterns are legendary. Like 800-X, SR 4756 performs extremely well in the big handgun cartridges. Always a top choice.
