Lehigh Defense working on tipped ML bullets
 

Lehigh has now added tips to be tested on three new bullets. The .452 265grn Copper CF, the .452 240grn CF, and the .451 230grn Copper CF bullet. For those wondering they are going back to the drawing board on the .40 200grn Copper CF bullet.



Here's two 5 shot 100 yard groups with a T/C Strike and the .451 230grn tipped Lehigh Copper Bullet. The bottom group was the first. I then moved the scope up and shot 5 more. All shots are with 120grns by volume of BH209.



This 10 shot group was at 100 yards with the .452 240grn Lehigh Copper Bullet. And the Knight Ultralite with 120grns of BH209



For some reason I forgot to take a pic of the 265grn Copper bullet.

There's still more testing that needs done. Adding tips will or could not allow the bullet to work as well on game. I'm going to send these out to Ron for his testing as well. I plan on testing the bullets as well to see what kind of velocity it takes to get them to work.

Here are some muzzle velocities with 50grns by volume of BH209.

200grn 1388fps
230grn 1240fps
240grn 1206fps
265grn 1184fps

From what I have read and see with the ones my sister has, those CF's are opened through hydraulic pressure entering a fluidic space correct? Seems that while those tips will drastically improve ballistic coefficient, terminal performance may well be drastically reduced from what everyone has experienced in the past with this bullet line.

There's a hole in the tip to allow fluid. Just the beginning of testing right now. The accuracy seams really good so will see how it goes.

Btw- I sold your sister her ML. I got some bullets I want to send her. Can you PM me her name and address so I can send them to her? Thanks

Yes that hole seems awfully small though. Looks like it will be much too easy to clog with hair and hide before reaching a fluidic region. An idea you may suggest to them is to score the inner side of that tip deeply allowing it to break outwardly away easily on contact with the animal. That would probably entail the use of a special tip on a ram rod like the spin jag for those high dollar pointy bullets by parker.

Wow Grouse you really like to push those bullet hard. That is good accuracy. But don't you think 120 gr of BH209 is a lot more than needed? Have you tried a lighter load?

Those are nice looking bullets and nice shooting!

Are they somewhat soft copper like a Barnes TEZ? I Full Formed (not a true FF as only the rifling is engraved) some 250gr Barnes TEZ yesterday, it worked quite well.


Send me some of the 265gr .452. I'll see how they shoot Full Formed out of my Brux 45 cal SML.

4 shot group of 250gr TEZ at 100yds

That is some amazing groups there. And I am sure if that bullet came out of Leigh it will perform very well on game. But that is really pushing a bullet Grouse. What do you suspect/think the velocity of that round is? That has to be well into center fire type of velocities with (as many tend to forget) a much larger diameter bullet to begin with.

I'd like to see them shot with 100-110gr bh209. 120gr eats up the can of powder to darn fast.

I like those bullets though. Steel tip or aluminum?

Very Interesting

Just laziness on my part. I weighed out all my powder at 120grns by volume for hunting. Plus I was calculating data for Sabotloader to figure out the BC of these bullets.
