Daryl, I thought the same thing that the Hornady 200 gr spire point would work very well at 358 velocity. No big need for a premium bullet. I have to admit that I will test the Barnes TSX as well since it has been so accurate in other calibers.
Reba, I intend to use a 1.5 - 5X scope as well.
I would get a BLR in .358 rather sooner than later. The lack of real world data for:
.358 Win with 200gr. TSX /225gr. TSX from the 20" BLR barrel
keeps me, yet.
I recognize, one does not need TSX at those speeds.
Still, Iwould be very interested in your loads and the speeds you are getting.
Please keep us posted.
Good Luck
