I would like to load some cartridges as title.
I am new to reloading, and have so far worked up one gentle but useful load for an old 7.62 target rifle.
Alliant's data for RL17 gives maximum loads for 100gr, 130gr and 150gr bullets as 59, 54 and 51.5gr respectively.
Apart from asking them (which I've done, but no answer yet), is there any safe and reliable way to deduce the maximum load for 140gr from this data?
Interpolation from the 130-150gr data gives 52.7gr, from 100-150gr data (omitting 130gr) gives 53.0gr.
Extrapolation from 100-130 data gives 52.3gr
What can one conclude from that lot?
That the maximum load will not be lower than 52.3gr or higher than 53gr?
That one should wait for Alliant to email back?
