I've had a 358 BLR for quite a while. If you want speed, Ramshot's TAC or XTerminator will give you between 2550-2600 with the 200's in it. I use mostly the 200 Hornady Interlock which last deer I shot with it was with 51.0 of TAC at around 2550 fps. At 200 yards and it went right through, busting out the opposite shoulder. IMR4064 is a great all around accurate powder in it, but it won't give you the velocity with it. In mine, 200's with it are around 2400-2450 fps with a max load. 48.5 grns with the 200 Sierra shoots great but is around 2400 fps. I use it for a woods load in one place I hunt where shots aren't more than about 60-70 yards. With the 225 Sierra and IMR4064, I was getting 2450 and good accuracy.
