I would not always think so but would like to hear everyone's input. Loading for a 338 EDGE AI 300 SMK's planning on starting at 90.0 gr of H-1000 and working my way up. I know i could shoot groups at 100yd but I would like to see how it groups further out, although it may do well at 100 this does not always mean the same for extended ranges, although I will check out groups at 100 also.
All that a good SD and ES does is tell you that you have a good powder, primer,case and bullet
weight combination. It may be accurate or not but if you have good accuracy to then you have
found the load for long distance.
In the process of working up a load the SDs and ES are what I start with when I get them down
(Preferably below 10 SD) then I start altering seating depth to improve accuracy or change to
another brand/type of bullet of the same weight to find out what the rifle likes.
I found that by using this method it saved me many loads and much time to get to the load that
