I will share a few things that are easy to do but I have found will help get you consistent results. Purchase these items: Imperial dry neck lube with application media and case sizing wax (or other brand as desired; it is just graphite), case tumbler (buy untreated bulk media and treat it yourself to save some money-I use walnut hull), case trimmer, full-length dies, and case prep multi-tool. I recommend a digital scale and trickling powder until it just reads to the 10th gr.
After firing cases clean them in the tumbler for a couple of hours and resize the to .002" headspace. I full length size everything in this way because I get better results but others have great outcomes just neck sizing. I apply the dry neck lube inside the case mouth any time they are resized or a bullet is seated. Apply a thin layer of case wax to the cases with your fingers prior to sizing. Trim the necks to within .002" of the recommended length, if they are too long. Make sure to use a quality case prep tool to assure no brass ridges are left at the neck lip after trimming. A slight ridge will cause the case to misalign in the chamber and result in flyers. Keeping these tolerances close will help prevent the cases from stretching and prolong case life. Cleanse cases in the tumbler for another couple of hours after sizing and trimming. Use a powder that will fill your cases to about 90% to achieve the desired velocity. I don't mind the powder being mildly compressed either. For rifle brass I use the primer seater on my Forster press to assure a uniform seating depth that does not protrude. Applying the dry case mouth lube prior to seating the bullet will help assure the bullet is not scarred and a more consistent seating depth. I recommend working with cases and bullets from the same batch for whatever brand you chose to use and working through sequential firings, i.e. continue through all your new cases until they are all fired then start on the 2nd firing unit all are fired twice. If you start with 100 cases and follow this procedure they should give you at least 600 firings depending on how high your pressure is. When they start failing I discard the entire batch and start on a new one.
You can start weight matching cases and bullets at some point but these few tips should help assure you get consistant accuracy. There is always more you can do but addressing these issues will get you in the ballpark. You will need to experiment with different powders, charges and seating depths but that will take another post. Just seat 0.015" off the lands and that will give you a good starting point. Enjoy
