as said have fun start pouring some and get a hang of the techniques that work for you and then throw any that are NOT perfect back into the pot set your standards high and you will always have accurate bullets. Some guys use not perfect ones in handgun as practice round. ME I like to have only 1 load and not have to worry about what box I grab. But yeah at 25 yards unless the bases are really bad (The base steers the bullet) most of them will shoot 3-4 inches, Me im such a lousy shot I need al the help I can get. And shoot only bullets that are as good as can cast which is about plus / minus .5% variance in weight.
