Being considerably older ,I would suggest getting rid of the .33. As time goes on recoil and weight will trouble you more.Contrary to many opinions,elk are not hard to kill. I have killed more than a few ranging from a 50 caliber muzzle loader, 4mag,.308, and 30-06..I did have a 77mm Mag for awhile.It didn't kill any faster or any better. I sent it down the road a long time ago.The.270 will do you just fine for all you hunting
