Nice rifle and a great classic cartridge!

I have a BRNO ZKK 602 in .458 WM and a Ruger Magnum Rifle in .416 Rigby with 1.5-5 Leupold. They are both very good shooters.

I have found the best way for shooting large calibers is from the sitting position with a set of shooting sticks. I'm able to almost achieve benchrest-sized groups.

Enjoy your new rifle!
