[QUOTE="Trnelson, post: 1808652, member: 42308"] ^^^ THIS EXACTLY!!!! The correlation between H1000 and Retumbo in a ‘6.5/06’ is NON-linear!! Simple equations of proportionality (XX/H1000 = XX/Retumbo) don’t extrapolate to safe loads. A 30/06 family parent case necked down to 6.5 is over bore, in that, velocity gained per grain of powder, does not track in a linear fashion, especially with 140 and heavier bullets paired with powders slower than H4831sc [/QUOTE]
