I have reloaded for a number of years, but primarily for shooting whitetail at less than 100 yards. I have always achieved what I consider accurate loads (< 1" @100) with most of my hunting rifles. After watching this site for a period of time, I got a wild hair to try my hand at longer ranges. I don't have the fancy gear when it comes to reloading...just the basic Rock Chucker press and standard RCBS dies. Out of my .308 Remington SPS Varmint my handloads have been less than 1 MOA out to 300 yards. I have not grouped any past there so I am not sure how it performs at longer ranges. Would it serve me well to ditch the standard dies in favor of the more expensive seating dies? I have been reading about runout and have never measured for this in the past since my loads have served me well. Now that we are talking about longer ranges this stuff seems to matter more. Basically, I want to make sure I am doing everything I can to make sure it's shooter error and not the rifle or bullet. Are there any other tips for more accurate loading? I have been using trimmed and sized Lapua brass, CCI BR2 primers, Varget powder and 175gr MatchKing bullets.
