Re: Suggestions for improving handloads?
Cody, if you believe that every little bit helps, then you may also wish to use a concentricity gauge on your finished loads. Definitely sort brass by wt. Turning necks helps but do it properly. Some say it isn't necessary on "good" brass, like Lapua.
I don't know about the rest of your loading technique but one thing that helped me years ago was a simple tip from a bench shooter in Tucson. When seating the bullet, run it into the die until you feel the first "seat," this is only the initial marriage of the bullet base to the case mouth...bullet is only in neck about 1/16". Back it out, give the brass a 180 turn, run it up the die again but only moving seating the bullet about 1/8 inch at a time. Back out again, rotate brass 1/4 turn, run it up again, back it out, turn in another 180, then seat all the way. This helps with a concentric seat.
You also check you finished loads in a mic right? It is a good idea to make sure all finished rounds are identical from brass base to ogive.
