The links 5pins includes take you off of THR, but they are worth the read, and at one point a Cutting Edge employee chimes in.
Note that 5pins was using an older Delta Elite and was having pressure signs early with 10mm loads. Older Deltas had chamber support problems, and it seemed that getting these bullets up over 1100 fps was challenging in a 5" barrel. The gent using a 6" after market barrel had better results out of his Glock, as would be expected. However, it should be noted that the Cutting Edge employee that chimes in claims he was getting 52" of gel penetration with a 1100 fps velocity.
I like the bullet profile and weight of the Cutting Edge. I am mostly interested in a bullet that will put some hurt on a big critter if need be. I'll be sharing my velocity data when I play with these bullets, and I did get some load data from Cutting Edge. I will be happy if I can get them up to 1150 fps out of my Sig P220 10mm.
Sorry, not trying to derail the thread or change the cartridge being discussed.
I realize these bullets are unproven in the real world but I figure they should at least perform as well as a hard cast while having the potential to perform much better if the ballistic gel videos are correct.
So, I've watched all the videos I could find on the Lehigh stuff, and done as much internet reading as I can. I was very interested in these bullets also. I think the assertion that these bullets should perform as well as hard cast is accurate when it comes to penetration. Barrier penetration seems to be where these bullets really shine. I believe that is true for the penetrators and the defenders.
The gel tests are interesting, but I caution folks against putting too much stock in them. A living creature is a mish mash of different density tissues that can really change the way a bullet works. The fancy flutes on the Lehigh bullets are clearly creating some pressure differentials in the gel that is tearing gel blocks in an interesting pattern. However, until they become more wide spread in use, and there are some real world observations made by doctors, and hunters who examine wound characteristics, we will not have conclusive evidence that these bullets perform any differently than a hardcast.
I'm not trying to poo poo these bullets or dissuade anyone from trying them. I have a few boxes of 10mm Penetrators from Underwood I'm going to try. I just want to caution folks on assuming gel tests mean anything truly relevant. Gel represents how a bullet
may act, and it is of course no guarantee. Temporary cavitation and permanent wound channel in gel means little to me, because there isn't hair and bone and guts and all the other crap in a living body in those tests. That's why I like solid flat points. Performance seems less in question.
These Lehigh bullets may be the cat's meow, but until I actually hear from someone who has used them on game, and observed a more than expected wound, I treat them as "likely effective" but not necessary for defense. Despite the fact that I carry whenever I can, I don't really see myself being involved in a situation where I need to shoot through walls, auto glass, or other serious barriers. SD shootings just don't really go down like that.
I choose Federal HST +p ammo for my 9mm and 45 acp defense ammo because it seems an acceptable choice that is unlikely to over penetrate. For my 357s I use Speer 158 grain Gold Dots. For scary critters I want penetration, and tha means the Extreme Penetrators, in something bigger than 9mm, or a hard cast, or a copper solid with a wide meplate designed to penetrate deeply.
That's just my own take on things. I hope folks who ever have to use these get good results, and if evidence shows effectiveness, I will likely change over. Hollow points are good, but can be inconsistent. Solid bullets are bound to be more consistent.
