RE: 358
My load for a 220 grain bullet in the .358 Win. is 48 grains of Win 748. This produces a velocity of 2330 fps.
My load for 200 grain bullets is 53.7 grains of 748. This gives me between 2450 and 2535 fps depending upon powder batch.
My .358 is a BLR as well.
My bullets are ones I swage myself, and there is no commercial equivalent.
