Mick,
The photos are coming up now.
Yeah, they don't look too good I'll admit but my opinion is that their impact velocity was too low.
I've done a fair amount of shooting with X bullets in various calibers and impact velocity DOES affect their ability to fully expand and also to hold together.
At velocities of around 2000 fps they often show very little expansion like those in your photos.
My experience is that they give their best performance at an impact velocity of between about 2300 to 2800 fps where they will expand nicely to about double the diameter, retain all 4 petals and almost 100% weight.
At impact velocity around 3000 fps they will often break off one or more petals and at velocities above 3000 they often break off all 4 petals and this is the reason that if they do exit it looks like they have not expanded at all as they only leave a small exit hole.
Exit holes IMO are not a reliable way of evaluating bullet expansion or lack of.
The X bullet really needs muzzel velocities of 2600 and upwards to perform properly IMO, and they are capable of killing really well.
Are those 286 grainers in the photo?
