Had a guy send me some of the Lehigh bullets in 9mm for testing... while i understand the idea behind the design... same as a WFN design hardcast. I was not impressed with the sample i had for testing.
Being a solid copper bullet, pressure was more than a lead cup/core or cast bullet which limited velocity.
The sample i had was also all over in diameter which ruined accuracy and ES in velocities.
This may have contributed to the tumbling in penetration test media, although (possibly same undersize problem) read of others test that resulted in tumbling also.
Would like to test another sample.....
Have not tested cast bullets in AR (gas gun) platform yet. Have heard others having gas cutting problems with plain base bullets or checked bullets with check narrower than gas port....
I machined a 215 WFN mold for 45 SUPER that works extremely well , need to see if i can make it work in 450.
With a .38 meplat it produces a 1"+ "hole" through deer at 1400 fps.
I have a 240 gr 45 cal mold i machined with slightly smaller meplat that would work well also if cast will work in gas gun....
