Best overall rifle for guys over 70

[mt terry d]

I’m good out to 500+. This season my shot was 335. No suppressor or break

I’m 70
I’ve been pretty successful through the years but never so consistently deadly (and at much longer ranges) since I switched from 300WM & 7mmWbyMag to 223 & 77TMK
This year elk at 260,310 & 510
Mulie buck at 440
Old dogs actually can learn new tricks
