ar-15 loads

i loaded 50 rounds for my friend to use in his ar-15 i used lake city brass, hornady40grn v-maxes and h-varget powder and i asked him how many grains of powder he wanted me to put in the book said 25-28 and he said 28(i think this guy has a death wish or something becuse i even told him it was lake city brass and the pressure would be higher but he insisted on 28) well like i said im usin lake city brass so theres no way im gonna put 28 grains in there and cause the gun and possibly my friend blowing up so i put 26 in but i didnt tell him and seated the bullet where my .223 likes them at

i went away from home three nights after i did this (so i can get my diesel degree) but was able to give them to him. im gona go home in november so i can do some hunting so ill try to get ahold of him and see how they worked
