I never tried the 200 gr. SST in my 338WM, but I have used the 225 gr. version and have yet to recover one that's stayed together, they do shred, leaving behind bits of the copper jacket as they exit. I've also used the 130 gr. SST's in my 270 and have yet to recover one that hasn't had jacket separation. I'm not concerned because they are accurate and definitely do their job, making a quick and clean kill. Since then, I've switched to Barnes TTSX bullet in both all my rifles, as they seem to be a tad bit more accurate past 100 yds.than the SST's.
