I acquired a rifle in .35 Whelen several years ago with the intent of killing a black bear in Arkansas. Went three times and never saw a bear, so I've quit going...and the landowner has gotten out of the business recently in any event. I'm hanging on to it for hogs. Unfortunately, I've never seen a hog while carrying it (which isn't often at all since I have quite a few other choices that are more versatile for targets of opportunity), so I still haven't killed a thing with it but I have no doubt that my 225-grain Accubonds moving at 2675 will take them down with authority. I'd like to prove that sometime before the great dirt nap.
Reloading the .35 Whelen, it's pretty easy to get good accuracy with low extreme spreads of velocity. Re15 and Varget work very well. I might be inclined to try some Re16 if I ever get my mits on some.
God I am hating caliber threads more and more
