Having shot tons of 140gr eld match bullets, I'd pick the 139 scenar over it. The 140 is pretty thin skinned and comes apart pretty easily. I know guys use the 147 with good success, but they use the same jacket thickness as the 140. Will they kill? Absolutely, but you are going to have a lot of lead fragments in the meat. The choice is yours. A 143 ELDX will hold together better than either of the ELDM pills you mention.
What constitutes "tons". How many game animals were in that mix? Impact velocities? I've killed a few deer with the lighter weight variety and they held together better than I expected.
Thousands upon thousands. The bullet has a very thin skin. I would not trust it on game I wanted to eat. Unless you like the taste of lead. Here's some that had issues:
They are an awesome target bullet. That is what they were designed for. You do take your chances with them though. I guess you've been warned. Just because a bullet punches paper and rings steel, doesn't mean it's going to be a top choice for a deer bullet. It will kill a deer no problem, but why put up with the mess of lead fragments in something you are going to eat. Or do you not eat what you shoot?
