First up thanks to Mrs Flyblown for putting the bullets together on the computer and Flyblown for the idea of cross sectioning the ELD X bullets. What strikes me is that the jacket walls look quite thick, when you compare these to a A Max jacket it is quite noticeable the difference in thickness. I also cut a 162 gr A Max and a 150 gr 7 mm ELD X but I don't think the pictures came out that well. When I compare the ELD X and A Max 162 gr 7 mm bullets there is a big difference, We all know that the A Max worked well especially as the distance increased so I can't understand why the ELD X would be opening up to quickly.
On most of the cross sectioned bullets it was very noticeable that they lacked the interlock ring or it was very small , you can clearly see it on the 6.5 bullet and it was visible on the 7 mm 150 gr bullet but not so on the others.
I think the initial question was that the bullet was over expanding but looking at the bullets they do sport substantial jackets so it shouldn't be an issue.
The 6.5 bullet does have a thinner jacket on the ogive, weather this is a problem at the velocity they are mostly used at I don't think so, we certainly haven't had a problem with them in a 6.5 X 55 and 260 at 2750 fps.
As @Flyblown stated a lot of problem comes more from bullet placement rather than the bullet its self.
It will be interesting to hear other people's thoughts.
