I have had 4ea 338’s. I mainly shot 250 grain Partitions. Two 700’s and two 70’s. I’ve switched to 300 Weatherby and 200 grain partitions (700 Remington)
I have a couple 45-70’s. One is a very light Marlin, not sure how that compares to yours.
The light 45-70 seems to rap my right hand more than kick my shoulder. My heaviest loads in it are heavy cast and are loaded stout.
I mainly shoot the 45-70 off hand and I’ve shot those 338’s a lot off hand and off the bench. I’m thinking that maybe a dozen shots from the bench with those 338 loads make up a day.
I can’t answer your question directly I guess, but they are both manageable. I’ve taken the 45-70 PD shooting and my buddies didn’t appreciate it all that much. Never thought of taken the 338 shooting PD’s.
