800y had a 56 in the first string and 59 in the second I used 42grs of 2209 and some 140gr Sierra match kings seated to just touch the rifling
was nice conditions today light winds in the first string and pretty still in the second string
Next week I will try some Berger 140gr VLD's at 900y

Good stuff mate , looks like u had fun . That's what's it's all about . 😎
Got any photos ?

a bold move starting at 800. good on you.
the lapua 136 scenar l also looks like it could be worth trying.
a bit lower in bc, but by all reports extremely accurate.
enjoy shooting a lovely calibre.
keep safe,
bruce.
