I'd hate to be any game within cooee, she reach out a long way this one!
Interesting choice of powder, rather fast for such a heavy bullet in a short magnum case?
I started with AR2209 (H4350) & my 308Norma which did not like that powder at all group wise even though I was getting factory velocity of 3000fps+ using 180gn Hornady pills!
Groups just shrunk remarkably when using AR2213SC (H4831), one of our 'Fly' shooters put me onto it when he saw my groups of woe!
Might be worth a try for you mate?
My only issue is my particular barrel fouls terribly, so it a 'more than a few beers' to clean that one!

For me recoil is sharp for the 30 Magnums lying down, they do come back very fast, a bigger slower bullet which even though has more recoil doesn't seem to 'sting' as much!
That group is nothing to be sneezed at for a 10 shot group by the way!
You always have interesting range reports, brilliant work as always.
