Default Testing the New Lehigh...

Lehigh Dave has made another new offering... a 40 cal 150 grain HP steel/copper plated bullet designed to work as does the brass bullets. His target group were younger adults, children, women, and even some of us guys. His feeling was the 150 grain steel bullet would greatly reduce recoil and cost per bullet.

This morning - I decided I really need to go shoot... We have a couple of football games this afternoon and thought it would be a good get away before the games....

The purpose of my trip was to test the "Recoil Reduction"... I can really tell you it certainly does reduce recoil. I started shooting at 70, 80, 90, 100, and 110 grains of T7-2f. I got to tell you 70 grains provided a recoil which i would compare to a 22 mag/17 HMR. By the time I got to 110 grains it still remaned very mild.... My only problem as I kept thinking in my mind "if it is this soft here - how soft is it at 100" I really do not know why I was thinking 100 because i was shooting 75 and all along I was thinking this could be a very effective bullet at 50 yards and probably to 75 yards for most people, after all a 50 cal round ball is a 177 grains...

My conclusion --- Recoil Reduction - It certainly did....

Here is the target from this morning outing. I was not really going to shoot for accuracy because of the wind conditions this morning. It was blowing hard here in Moscow so I knew it would be worse at the farm. I set up the chrono about 10' off the muzzle and the target 75 yards down range. My portable shooting bench was protected from the wind for the most part as grain silo blocked the wind... but 30 yards down range the bullet was exposed to the full force angled wind blowing up the draw.
I always worry tomuch when shooting through a chrono so i always formulate a few nerves in that + I knew the wind was going to complicate things... But got it done...



Again for me the bullet certainly shows it can be shot accurately....

ENERGY? the big question... I broke out my big Sierra reloading manual flipped to the 30-30 Winchester and decided to check the 150 grain flat nose bullet velocities and energy levels...

At 1900 fps (lowest velocity level in the manual) the bullet is developing 1202 fpe at the muzzle... then
2000fps = 1332
2100fps = 1469
2200fps = 1612
2250fps = 1686
2300fps = 1762

So my conclusion is that this 150 ML bullet with very low recoil will match what we use to achieve from a 30-30... I can not even remember how deer, and mule deer to-boot, that I shot with my grandfathers old 30-30 when I was a kid.
The final question.... which for me remains un-answered at this point... will the bullet perform as designed? Dave has indicated that he may need to score the petals... Guess time will tell.
Wish I could find some peepers to shoot...

Good report. Will be interested to hear what it does when you take some game with it.

Nice report! Accuracy looks good- but like you said, what remains to be seen is performance on game. I was kind of surprised at the velocities you were getting with 110 grains T7 - I would have thought they would be higher for such a light bullet. I'd wager that if you shot the same bullet/powder charge out of a .45 cal rifle, you'd get higher velocities. But it should still get the job done for sure.

Really a good report there Sabotloader.. interesting results. What twist did your rifle have?

Dave it was the Disc Extreme 1/28 twist... Grouse used a 1/30 Knight Disc Elite to do his test, but since 5 of 6 Ml's out there are 50 cal - He wanted to get some shot from a 50 cal...

Thet realy did shoot nice... i wish i could find the time to set up a water to sand test to make sure the petals function correctly.

That velocity is about what I expected... the bullet is to light so T7 gets it out the barrel in a hurry. I was going to shoot 120/130 grain loads but I am sure I would have run up against the 'law of deminshing returns' and remember I am shooting near the 3000 ft level... flat landers get better velocity..

Lehigh has not completed the bullet for sale yet. The bullets that Grouse and I got are the prototype for testing. I believe they have passed the iniatial testing by both of us. The significant test still reamains and that is how they might perform on or I should say 'in' the game animal. I am hoping to run another test in the near future that might help answer that question.

I should also say that 'by' design it is suppose to work, but has not been proven as yet that I know of.

Also, Lane quoted the price that has been suggested to us. Right at $30/100 to your door.
