just a quick question, i have got a booklet called "the complete reloading manual for the .270 winchester" to cut a long story short it has most powder and bullet manufactures recommended data in it.
now the question is, take for instance 130 grn bullet\reloader22.
nosler state their max load is 58grns RL22 giving approx 3100ft\s.
sierra states a max load of 58.2grns giving approx 3100ft\s.
but alliant say 60grns as a max load.
and hornaday quote 61.3grns as a max load giving approx 3100ft\s.
i know you always develop a load by starting low and building up, but why should there be such differences surely a 130gn bullet by any make should be the same.
