I'm 78 and I cannot hunt like a youngster. Hiking the mountains is out. I dumped my last magnum some three years ago. I still have some twenty or so rifles. Most all have a standard '06 or .30-30 case head, except the five center fire .22s and a .357 short rifle.
About thirty years ago, I purchased a matched pair of Browning, small ring Mauser actions, with pencil barrels in .243 and .308. Both are superbly accurate and the .308 is amazingly so. My big gun is a 9.3x 62. Truth be told the ..243 and .308 with modern bullets would do everything I will ever do from here on.
My Kawasaki Mule lets me hunt. I can get to or close to food plots, water holes, or game trails. Texas lets me hunt from the vehicle, but I often build brush hides to watch from. The Warn, cable, ropes, and pulleys help retrieve stuff without a great deal of effort. If I bite off more than I can chew, sons-in-law come in handy. Can't find one of them, go to town and look. There is usually someone that will assist for a little fresh meat.
I don't need stainless. If it is wet, I will wait for another day. Other than operating equipment at harvest time if needed, I don't have a job. Getting old is no fun, but it has a few advantages.
Besides that, I let most of the Bucks walk. I'm waiting for muy grande, or a fat barren doe. The does eat better and we do have too many.
Best,
Jack
