I forgot to mention i also tested the 250grn Lehigh at 200yards. I used 130grns of BH209 and a Knight Disc Elite 50cal. The picture above was a mirror image of the results at 200yds. At some point/range the Lehigh will work like a conventional mushrooming bullet. Those petals require i believe 1000fps and liquid to shear and come off. I'm very happy out to 200yards to say the least with both 50 and 45cal Muzzlleloaders.
I plan this weekend to do the same test's with the 200grn Lehigh. I dont expect any issues because the 200grn bullet will be even traveling faster then the 250grn.
Here's a picture of the bullet after the petals have seperated.
