I'm very happy with a 1/2 min. rifle. Once I get to that 1/2 area, I'm done playing with the load and get to shooting distance. I only get so much time to reload and to shoot and I'm not chasing a load and wasting components.
This ^ is the standard and process you want to aspire to.I want a forgiving load that holds together hot/cold, warm weather/cold weather, etc. etc..Most all my finish work with a load is done at 200 yards. With my LR hunters andPRS/competition rifles at this distance I'm looking for 3-5 shot groups minimum of .75" (.36MOA), with SD's in the <10 range. I will stay on top of my rifles to make sure this level of performance is maintained. It also checks "my" level as well. Might sound like overkill to some but going on 12+ years with this standard, for me, the end justifies the means. IMO.
.25 MOA gets me out to the neccessary F.P.E. accuracy for both my cartridges, .308 WIN & 300 WM. 900yds & 1472 yds. respectfully I can live with.I have a Tikka T3X Veil in 6.5 PRC, I am loading 143 ELD-X not because I particularly care for them but that's what shoots so far. I am using RL26, Nosler blem brass and Fed 210M primers. If I have not had much coffee, it shoots .5 to .6 at 100. My intent is to use it for whitetail to 800 yards. My longest shot so far is 519 yards with a 257 weatherby. Is there any point looking for another 1/4" of accuracy since I will be shooting off a bipod in field conditions?
