Having had 9.3x64, 9.3x62, 35 Whelen, 350 Remington Mag, 338 WM, a bunch of 338-06's, and 30-06's.
I have a 375 H&H for the bigger end. Currently have one 338-06, with a suppressed and African style 338-06 in the works. All are Model 70 Classics.
I prefer the 338-06, it is a nice addition to my 270's. Have used one in various guns for close to 20 years. I have used mostly 200-210gr bullets, but have recently started shooting 180-185gr. Plan on taking one to TX in March for some hog hunting.
