kunas...it is a sweet little cartridge. I happen to have a .30 Herrett barrel that belonged to huntkng. Accuracy is great...usually sub one inch groups at 100yds and ringing a 10" steel plate at 300yds is childs play.
It's a great 150yd deer cartridge when loaded with a 125-130gr bullet. Mine shoots the 130gr Hornady SP very well with RL-7. It's accounted for several deer between 65yds and 110yds, including my biggest buck...a non-typical 13pt.
