Check the BC of the 225gr Accubond vs the Partition. Accubonds are bit cheaper but I doubt they'll perform any better on game and they won't work in some short actions without deep seating and eating up powder space. I have used the 358 in a BLR quite a bit. To me it is a very well balanced package. Light, short and easy to carry. Packs well in a scabbard. Not a lot of recoil and a mild report. It can be as accurate as any cartridge based on the 308 case and performs well out of short barrels. I think the 225's are the ticket in the 358 although not needed for whitetails. The round is devastating on deer even with 200gr bullets although i see no advantage to using them. I don't feel that "premium" bullets are needed either although I use Partitions when traveling far and writing a big check to hunt. I'm sure the Sierra's would work well. I can hold on hair past 300 yds and still have over 2000 ft/lbs of energy for you numbers guys and still have enough velocity for reliable expansion. My longest shot has been right at 200 yds which went completely through a bull elk and my closest was 20 yds which penetrated over 3 ft of bull moose. Steaks from both are delicious btw. You don't really have to worry about bullets blowing up at essentially muzzle velocity with the 358. I have not been "range limited" by the cartridge, only by opportunity. Relatively cheap to reload for, doesn't use a lot of powder. What's not to like? I don't believe the 338 Federal will do anything better in the real world. It's only real advantage is factory ammo which I don't care about anyway. I wonder how many factory loads will be available in 20 yrs. The fact is over 30 caliber rifles just don't sell that well in this country. If I didn't already have a 358 the 338 would be a good choice. More bolt rifle choices, at least for now.
