Sight in your rifle during a heat wave, fill your tag when it’s subzero. Another new Enduron Technology extruded powder, IMR 4451™, gives top performance in the venerable .30-06, .270 Winchester and .300 Winchester Short Magnum, to name just a few. This propellant is ideally suited for numerous mid-range burn speed cartridges. It’s a new habit that will become as second nature as opening day.

I didn't think anything would outshine my ol faithful 4831 in my old 284 Win I built back in 63, but by cracky, this stuff does. Loaded w/ 54 grains pushing a speer 130 b.t. out of a 26" tube, it snorts & very good groups too. (Posted on 2/17/2017)
