Re: Bullet for elk ?
Red hunter, I would start with a proven powder that is not temp sensitive such as H4831, or H1000. I then like to determine what a max charge is with a given load by shooting two shot groups. I would then back off about 3 grains under max and keeping everything consistent, try several different seating depths from just into the lands, if you are shooting vld's, and then backing off about .020" per load. Shoot at least 3 shots min. and see what groups the best up to max. I would then repeat that load and load .010" each way for seating depth and try again. When you have determined the best seating depth, change your powder charge by increasing in 1 gr. increments until you reach max and again, choose the best group and load 1/2 gr. each way from there. You can then try another powder starting with your best seating depth.
Everyone has a little different approach, but this works for me. For long range, try to find a combo that has a low e.s. and at distance, a low vertical spread on target. You can play with primers to fine tune a little further at this point if you want....Rich
