Load data 7mm/300 Wby

[Chief]

I have read from this forum several members have owned and maybe still own and shoot 7mm/300 Wby's. Looking for additional load data for this chambering. My current load is Wby brass, Fed 210M primer, 73.5 grs IMR 7828, Sierra 168 gr MK. The gun is a Rem mag action with a 30" Shillen barrel and a Vais muzzle brake set in a McMillan MBR stock. It has a leupold 6.5-20x50 long range mil dot scope in Burris Signature Zee rings on a Baer tapered base. My goal is to shoot light gun 1000 yard benchrest and long range deer hunting. Thanks in advance for any help.
