Can anyone help me with a load that has a similar setup? Thank you in advance.
Go buy a box of the remington factory premier full power loads with the 180gr Scirocco II bullets and see how they shoot for you.
If they do then pick your favorite large magnum power like RL-25 (93-94gr), H-1000 (93-95gr) or Retumbo (99-102.5gr).
Another very good high BC hunting bullett in that range is the Hornady in either Interbond or SST.
Should be great on deer to 1000 and more than adequate on even Elk out to 800yds.
Always safest to start about 1gr below what's recommended and work your way up evaluating for accuracy, speed, and of course pressure signs.
Best to go ahead make sure it's free floated and properly bedded before starting to work up an accuracy load.
