Anybody worked up .243 loads using speer 100g soft point boat tails with either N160 or Accurate 4350, if so what works best and at what weight of powder?
I've looked at both of powder manufacturers data and they both differ from my mates quickload programme with the programme saying the weights in the manufacturers data are over the maximum, so obvioulsy, who's data do you trust?
The other question i have is around C.O.L,(2,650") according to the powder manufacturers data, what is the acceptable tollerance from the C.O.L in the loading data? by this i mean how far can i incrementally reduce the C.O.L to try and improve the grouping?
please feel free to explain at my level, i am a relative novice at reloading.
