We just received a box of 90gr Absolute Hammers and I promised to wait till Xmas for a few reloading goodies that my wife/hunting partner knows I was wanting.
(270 and 280 resize dies) for necking down LC '06 brass.
Both the two rifles we have are fast twist
Tikka is a 1"-10" and I believe the Browning is a 10.5"
I think you may find H4350 or my personal favorite for many '06 based cartridges, H4831sc
I'm running 115 gr. Partitions in both guns currently.
Tikka's sweet spot on the high node is 53.7 gr. and the Browning is 53.15 gr.
Theses are above book loads for a cup-core heavier bullet.
I have ever tried H1000 Or Retumbo in an '06 based case.
Will you be using standard primers or magnum primers ?
