One thing to remember is that we use our doubles very differently now when compared to the Bells and Taylors or pre WWII days. Ammo used to come in 5 round packets and I reckon the average pro elephant shooter only fired 100 rounds a year. All factory, no working up loads, no practice, no Big Game Rifle Shoots. I fired 100 rounds from my 470 last week, just working up loads.

So, I think, if you really like your rifle, lower pressure loads are the way to go.
