Lovely piece there Ovenpaa.
Kuduae as always a trove of knowledge & saved the day!
Might be better to go for a lighter constructed projectile if you want to shoot lighter game.
I wouldn't use the heavier weight 6.5mm projectiles on small stuff, they're built very well & just pass straight thru. My father in-law has an old 6.5x55, we reloaded the military/target loads with 120gn's & even those just zinged through kangaroos!
