Anyone here pushed Woodleigh bullets over the max recommended velocity ?

Shot the 500gr Woodleigh RN at 2300fps out of my lott on a sand mound.I think the recommended vel. is around 2150 fps.It didn't hold together like my A-frames or the 550gr Woodleigh RN.

.

It's strange that when I recovered a 500gr TSX I used for finishing off a buff it was stressed way more than it was when fired on the sand mound and I have fired many 500gr TSX's into a sand mound.Woodleigh 550's are the bullets I chose for setting my sights on my Martini custom lott.Here is a picture of my chosen ammo.[URL= ]550gr Woodleigh RN and FMJ and Norma brass[/URL]They look much prettier than in the picture.
