I echo the comments of 500WE. I have been using 23g or 23.5g of H-110/WW296 with 240 grain bullets since the late 70s. I shot R-Int class with this load in a DW44 and a RSB. I shoot it in all of my hunting 44 mags. A terrific load.
I do agree that ammo should not be solar cooked in extreme temp. and sunshine. I live in PA and do not have much of an issue. Most of my hunting is in cold weather.
