Re: What factors effects accuracy of a load most?
what effects accuracy the most depends on the distance your shooting , factors at 300y and factors at 1200y are very different. If your shooting "close" it would be ideal to use a flat base bullet and not a boat tail. At close range having a "bad" SD/ES isnt really an issue , but the further out you go the more of an issue its going to become. Bullets with high BC's are more desired at long range. So , it depends.
-Bullet choice , probably the number one thing , try shooting some shitty 55gr at 500y with a .223 , then try a 75gr smk or vld , it becomes evident.
- Primer choice , not so important , i think good primers is about consistency , no point in being consistently bad right cheif ?
- Brass choice , pretty important as this will effect allot of things , runout , Case Capacity , stuff like that
- Brass sorting (case capacity) sorting by CC and weight should yield very similar results , if the CC of a round is 1 or 2 grains less then usual , more then likely the case weight itself is off by a similar amount , at least from what i have observed. overall not important , runout is more critcal
- Brass sorting (by weight)
- Bullet seating depths , this is important <span style="font-weight: bold">but</span> i think there is some room for error , like maybeeeeee +/- .002 from whatever might be ideal, maybe less. but you got to find whats ideal first
- Bullet neck tension , i dont think its "important" but if you have low neck tension you might get delayed ignitions , if your using to much your bullet will act like an expander , your runout will probably suffer. .003-.005 is normal i think
- Runout , somewhat important , nothing i'd overlook though , it depends on what your trying to accomplish.
- other?? proper OBT/OCW is very important ,
you didnt mention meplat trimming , i would worry about that over measuring CC in water , what a pain in the ass that would be.
but , having a good barrel scope, shooter , all that stuff is more important , obviously.
