Dupont IMR4831 Smokeless powder. a little over 3-1/2 lbs (3lb's-9 ounces in the bottle)

Dupont IMR 4831 is a versatile rifle powder used in a wide variety of calibers, including the .270 Winchester, .243 Winchester, .30-06 Springfield, 7mm Remington Magnum, and .300 Winchester Magnum. It is particularly well-suited for heavier bullets in these cartridges, providing excellent accuracy and velocities. 

I am getting out of reloading and used this for my .270Win with 150 gn Nosler Partion bullets.

Excellent accuracy with my Winchester Model 70. Killed a few moose with this load.
