Cayugad, IMHO, what I see this bullet and all LH for that matter do is shed their HP peddles shortly after inpack, then they become a wide metplat bullet. they don't over expand from that point on they just penitrate. The wounding ability of a wide metplat is the direct results of tissue spray off the flat nose. 1500 fps is the
ideal maximum for this,
if the speed is higher there is a larger hole but slower killing effect due to the destroyed tissue cells automaticly clotting and slowing the blood flow. Now Grouses initial velocity is much higher than ideal, but it takes energy to blow the nose off these bullets, there is no free lunch, so the energy transfer slows them down.
The reason they are effective isn't because they are holow pointed, it is the become a wide metplat bullet!
I have also killed much game with a conicle and have thrown alot of meat out. it has been my findings that the soft conicle creats tolarge a metplat for its speed and this results in to much damage.
Get a copy of Veral Smiths book for his LBT Mold "Jacketed Performance from Cast Bullets"company and al of this will be explaned in laymans terms.
Some here have stated poor results from a hard cast bullet w/ a wide metplat, it is my opinion that they were driving them to fast and that is why they had poor results. I have had excelent results with Cast and a big metplat but I understand the relaition ship of metplat size and speed to acheive the proper "DV" (Displacment Velocity).
just my 2 cents and change!
I have not shot or bought and have no desire to shot any Lehigh bullets. I am very happy with my LBT LFN hard cast, that I cast myself. that doesn't mean I don't see that they are a good bullet. I new of Lehigh Dave when he first started tinkering with bullets. John Eggleston was one of the first to us a lehigh in 50BMg 1000 yard shooting, i beleive he placed very well with them and many competitive shooters today launch them.
As soon as a expanding bullet mushrooms it is simply a wide metplat bullet! the problem is controlling the metplat size. hence to much metplate for speed, now there is to much tissue damage!
