[QUOTE="bigngreen, post: 828056, member: 13632"] I think that maybe putting this bullet into a media that would provide more hydraulic action in the tip may result in something different, pilling this bullet into a board may just turn it into a solid because of tip damage. With the cup and core bullets the bullets can break in half or collapse exposing softer material that will expand but with mono bullets we don't have any back up if that nose does not open which in my mind make the method of how expantion starts much more critical. The impact velocity was calculated with a .306 G7 BC so it could be lower but not below 1800 fps for sure, many long rang bullets will open at that velocity and that is why I'm interested in the CEB, it has many characteristics of a long range bullet but it must open at that 1800 FPS mark or it is really only suitable for standard hunting ranges. I think the 6.5 cal can be a hard size to get what you want, you have a narrow frontal area combined with a long straight bullet, even some of the more frangible bullets in other cals seem to hold together better in the 6.5, I would expect a 338 bullet to initiate expantion easier with the addition of a huge frontal are. When testing bullets it a bad assumption that one cal reacting in one way is an indicator that all of them will react the same, sometimes you need to tweak something because the forces on the bullet has change enough to need a design mod. Hopefully no one takes my post as the bullet is scrap, it just needs to be modified or the test needs modified or maybe we just flat went beyond this particular bullets capability but shooting and reporting then hashing it out is the only means we make gains in knowledge.
