Well I'm glad I viewed this posting, I was in my local gunshop not more than 2hrs ago mentioning to the owner that I've had my first Woodleigh failure, not from breaking up but from non expansion, a perfect 80mtr shoulder hit on a adult Sambar hind out of my 375H&H, (270gn PPSN ) a day and a half later I found the hind some 300mtrs from where I shot it (dense bush) the entry hole was the same size as exit hole, the shoulder blade had a nice .375 hole in it...hhhmmmm....Les
