Howdy.
I have a Parker Hale 1200 in 30-06. Nothing flash just a straight worker.
The best load I have put through it has been Hornady 165grn spbt. 56 grns of win 760 gave me 2760 fps and on a good day, a three shot group at 200m of 16mm center to center. All most forgot. It has a 3-9 bushnell.
It do's not like any projectiles below 150grn.
The biggest thing I have used it on is jerrassic rats.
I am hoping to bag a deer with it soon.
