I'm looking for a velocity of about 2000-2100 fps which is similar to the Kragicon load -- I'm worried it's too much but I have no data whatsoever for the 8x58mm so I'm figuratively shooting in the dark right now trying to figure out where I should be going with this. Judging by what you shot very well with, it would appear that perhaps I'm too hot with my load, though at 1600 fps I saw keyholing on a few rounds.

Back to the drawing board!
