Well I got to shoot about 1/3 a pound today , and I like the stuff . The "mag" part of the name is right , this stuff has some kick to it , I didnt care for 100 grains with it out of a 22" barelled savage , strong recoil . The amazing thing is at 90 grains its not bad. As for the claim of "clean burning" well,,,,,,,,,,,,,,,,,,, its better than 777 but it is not clean . It leaves a whiteish waxy residue , cleans very easy , 1 alcahol patch and 1 dry gets it sqeeky clean .I got some good accuracy out of it , 1 inch groups at 50 yards , and realy didnt have time for 100 , no scope either and 100 kills me with open sights .
